The open source high-end Memory Player

December 2007

Music delivery is perfected. cMP (cics Memory Player) delivers memory playback (without RAMDisk or other utilities) thereby eliminating disk interference during playback.

In creating cMP, its critical objective was the implementation of fundamental designs that:

  1. Remove disk traffic interference during playback without having the inconvenience of manually loading files into a virtual RAM drive, etc..
  2. Ensure time critical sample delivery to the external DAC. Streaming of samples from precision upsampled (to 24/96) sound buffers to the soundcard must be fast, lean and mean! There's no room for any bottlenecks or overheads here, otherwise we risk increasing jitter and compromise Bit Transparency.
  3. Provide better power supply and remove the need for a ferrite core on the mouse connection.
  4. Provide flexibility to choose any player (Foobar2000, Winamp etc.).
  5. Further minimize the Windows footprint to that more optimal than XP's Embedded SP2 operating system as used in large scale commercial applications. This provides the foundation for the 2nd design goal.
  6. Offer a CD/DVD-ROM drive without impacting sound quality.
  7. Offer proper remote usability as locating that mouse cursor from a distance is cumbersome.
  8. Contain costs but also allow for a complete elegant one box solution.

Such designs in theory should render a stunning sonic experience. Its implementation however was a massive challenge. Did this theory meet the sonic expectations? Yes as evidenced in cMP's bit perfect performance and ultra low jitter.

How does it sound? The most descriptive word that comes to mind is emotional. cMP's sonic purity is truly profound. It grips those musical lines across any genre with remarkable precision. Soundstage improves, there's better layering and even more ambient information. Bass is tighter, with natural vocals & instruments.

FEEDBACK

Pre-release testing by music lovers located all over the world yielded further insight and perfection of cMP.

  • A music lover based in the US with limited or no computer training:

    This has been a great way to learn about computers in addition to making something very useful for enjoying music.

    Compared to my ###### (read expensive high-end traditional CD transport), even with some tweaking and learning left to do, this sounds much better. Dynamic, yet relaxed (effortless?).

    I started listening last night at 7:00 and had to force myself to go to bed at twelve. Amazing spaciousness. It is truly getting close to GREAT analog and is much better than average analog already. It is simply amazing.

    I found your instructions easy to follow ONCE I understood what I was being told to do. To repeat, I have never done anything like this before, so your instructions were clear without resorting to "hand holding". I think the process was easier than you warned. I kept saying to myself, "that wasn't so bad!"

    After cMP:

    My only audio friends are very analogue-centric. Sometime in January I am going to have them over to audition the cMP. I think they are going to be amazed. Of course, I am confident that JULI@ is going to be the icing on the cake. If this takes the whole thing another step closer I think they will be grateful that one can enjoy listening to CD's as much as LP's. Of course, in many ways your approach does things even LP's cannot do. It is becoming a toss-up, but the best kind; one can enjoy either one equally well!

  • A music lover based in Europe with more than 2000 CDs:

    the quality of sound reproduction is quite amazing. My motivation for building was that I am not wealthy and could never dream of, let alone buy, a high-end CD player. Even this project was considerably more than I could properly afford and I began it with some trepidation. But it's been well worth it.

    After cMP:

    I spent several hours last night testing the latest cMP. I did several A/B runs with cMP on the one hand and Foobar launched via old batch files and reading direct from disk on the other. There is no doubt in my mind that the sound using cMP is a significant improvement even with my modest setup.

    The quality is quite stunning, significantly better than previous. (My partner agrees with this - she's no audio junkie but she is an informed music lover.)

  • A music lover based in Australia:

    I have been wanting to relay to you my own experience with your methods and give you some feedback . So far, I have found your approach produces very good results so I must convey to you my thanks and appreciation. At some point soon I will formalise my thoughts and send them to you or post them. I believe what you have done has become an excellent resource/asset to people interested in PC Audio.


FEATURES

  1. Disk traffic interference during playback is eliminated. Advanced RAM playback is based on available physical RAM (as reported by Task Manager or Process Explorer). This means up to 4GB (XP's limit) can be used allowing for 24/192 RAM playback. Recommendation is to use 1GB RAM (which yields available physical RAM of ~830MB - enough for any CD at 16/44.1). cMP achieves memory playback via the system cache and not through a simulated virtual drive. This approach removes Windows disk I/O overheads (irrespective of whether disk is physical or virtual) hence, it's more optimal.

  2. Extensive Windows & Player (Foobar2000 or other) optimizations yielding much lower jitter and bit perfect delivery. System level optimizations are done at runtime (which cannot be achieved using .bat files and utilities like Process Explorer). cMP is designed to work with 32 CPU cores!

  3. Open architecture. cMP allows for any player to be used: Foobar2000, XXHighEnd, Winamp etc. (player just needs to handle .cue files like foobar2000 otherwise play entire .wav). Any ripper software can be used (as long as it conforms to .cue single file standard like those created by EAC). Additional flexibility is provided, for example use cMP to drive your HTPC playing any movie from any genre (a .cue file for each .iso file is needed).

  4. All .cue files are processed by cMP which means the player focuses only on playing the CD. In Foobar2000, the album list control component is not needed. In techno speak this is called separation of concerns.

  5. Power delivery to the mobo is improved by further reducing interference. The need for a ferrite core is removed.

  6. Full function remote control using a wireless mouse is achieved. Your entire library can be navigated: play any CD, eject it, jump to any track or change volume. This is achieved using just ONE mouse button: the Wheel! Use the mouse as a normal one (left-click) or hold it in your hand (like a remote control) and wheel away using your thumb. Of course other buttons are used for more convenience. There's no need to find that tiny mouse cursor and left click! (You can still do this if needed).

  7. Your entire library that you so diligently ripped is fully compatible with cMP. No proprietary / lock-in stuff here which forces you to re-rip. Just point cMP to your music folders containing .cue and .wav files (or flac or other). cMP supports any content file as long as cue files are defined for them. For flac content files, the known EAC bug of adding an additional .flac suffix to the content file's name must be removed (otherwise your cue's content file directive will not be found).

  8. CD/DVD-ROM drive is implemented without compromising playback quality. For the purist, this can be unplugged without opening computer or rebooting.

Bottom line: cMP is a (one box) highly advanced memory player that's easy to setup and use. cMP's core strength lies in newly developed operating system software components (built in c/c++) that uses XP SP 2 as a foundation. Windows Explorer is done away with while cMP takes over and more. Bit perfect delivery is achieved yielding an ultra high resolution of more than 23.5 bits (a limitation in measuring instruments prevents measuring cMP's perfect resolution). DAC's have yet to achieve this resolution (as a minimum of 141db SNR is needed)! For cMP's bit perfect measurements, see (Bit Perfect Measurement & Analysis ).


GETTING STARTED

Visit cicsMemoryPlayer.com where you'll find detailed easy to follow instructions and much more.

Ensuring clean AC power delivery to equipment is very important. For DAC, pre-amp and amplifiers, use a dedicated AC circuit. For source equipment, use another AC circuit as this is where cMP's main PSU should be powered from. Use another less important AC circuit for powering cMP's 2nd dirty power inlet. Use of quality power cords and line conditioners is recommended.


Special thanks to those that provided such brilliant feedback and suggestions during pre-release testing. cMP's software is at version 1.0b as more feedback is desired. Your input, insights, criticisms, experiences and suggestions all help.

Thank you.

 I measured it to confirm I wasn't going over the current limits of the LT3080 I wanted to try a few weeks back.

As far as hearing a difference, I have here three HDD's (500Mb WD, 640Mb Samsung, 1Tb WD) and will be swapping among them to see if I can hear any differences between them... I also want to try home-made SATA data cables (Ala Peter Daniel... anyone got a source for SATA cables with snap-on ends? I know they are available... but I can't find them!), additional bypass caps at the HDD, screen, and USB connectors, and I now have copies of both XP SP1 & SP2 and need to setup a dual-boot setup so I can compare them.

So many things to try, so little time!

LOL.

Makes a lot more sense now, we were talking about two different cases... I figured it was something like that or variations across different production runs.

On my dirty supplies, I have one raw DC supply that feeds about 18v into an LT3080 that is set to provide 12v for the monitor and that also feeds another LT3080 set to 5v for the USB header for the touchscreen and remote mouse receiver.

Then I have another raw DC supply that feeds about 10v into an LT3080 set to 5v for the HDD.

I did find that component quality was audible on these supplies in my setup... Jensen 4-pole and Black Gates were better than Elna Silmec-II which were better than Panasonic FM/FCs. This still surprises me!

Next thing to try here are additional filtering caps at the screen and HDD power inputs... I guess I'll try it at the USB header too, but don't expect there's as much potential there.

Greg in Mississppi

P.S. In my setup, it made a difference to reduce spurious vibration in the case. I:

1. Removed all un-needed circuit boards and parts (such as the drop-down door in the front)

2. Applied Dynamat Xtreme to damp the case's panels.

3. Used damping rings off of Herbie's Audio Lab's original tube dampers on the motherboard mounting studs.

4. Set the case on Herbie's Iso-Cups on a low stand with a damped glass shelf.

5. Added more damping on the case top with Herbie's Supersonic Stabilizers.

6. Mounted the HDD to a small square of bamboo which rests on Herbie's Tenderfeet with a poor-man's VPI brick (old transformer core covered with heavy heatshrink) adding more mass on top of it.

7. Decoupled the dirty supplies on Herbie's Tenderfeet.


Everything matters!

 Rick I was a late comer to the 2.5" hd's. I used 3 3.5" disks and because of the electrical reasons mentioned above by Mihaylov the 2.5" disks put a lower strain on any power supply and yes I heard more purity with 2.5" disks. Just think about the ssd's... they are a further reduced load on the power supply and they definitely sound different (but not necessarily better). They are too 'upper bass' shy sonically in my system. The 2.5" disks are just right for my system balance.

 Hi Guys,

I'm about to switch to core-i3 and I'm curious which mobo would be better. I have a regular ATX case. GA-H55M-USB3 (ATX) seems to have better filtering, but I'm not 100% sure. I'd appreciate your help...

 dear forum experts,

there has only in fragments been information/ discussion on cMP2 with latest hardware available on the current market...or so it seems.

if one where to build a cMP2 system from scratch nowadays, I could wonder where (if any) advantages are by using win7 with which motherboard and which processor.....and what about using SSD for at least the systemsoftware ?

if I have understood microsoft correctly, win7 does not feature a "minlogon" possibility, but can be ordered in different embedded versions.
have anyone tried these tailored win7 OS ?

could we start a little tread on these issues ??

kind regards

 dear mihaylov,

thanks for all your outstanding contribution on this forum !

you have been keen on promoting the i3-530 CPU and the H55-3USB board several times, and made us understand that your experience is it´s superiority against previous XP based setups.
could you clarify if the XP version was completed with minlogon and all the recommended mods ?

is your current setup (win7 I guess) in any way software modified ?
how much does win7 allow to reduce and/or slim-down ?

windows does an embedded win7 version for industry applications....has that crossed your mind ?

we are eager to get some more information from you pioneers :-)

kind regards

 if one is powering the HDDs from the same supply as the computer I can easily see the advantage that would arise from the one requiring the least power BUT if the HDD has its own supply I cannot imagine it could possibly make a difference.

I used to use the originally recommended 2.5" HDD's (were they SAMSUNG? can't remember, when I changed to the WESTERN Caviar Black I heard no difference whatsoever, but that is simply my experience.

Maybe I am lucky but the WESTERN drive makes a little noise when starting but after that is silent. It is placed on a sorbothane pad within my think walled wooden box. Even if it did make noise it would not be heard from the listening sofa.

Just my experience.

Wish I was brave enough to try an SSD for software but I have read too many stories of difficulty with XP and SSD so I will wait.

 Hi Mihaylov,
thanks for all your help.
Have you tried using 256mb of RAM? Did you see any difference in sound quality and/or power consumption? Why have recommended RAM changed from 256mb to 1gig?

I'm curious because I'm currently using a Peaktech linear psu (3A/15V) powering the P4 and the P24 (combined with a picoPSU).
Do you think 3A would be enough to power such a system?
From your power consumption details, 3A looks really borderline...

Thanks

Etienne

 I think 256 MB too little. A minimum 512. I use that memory which remained with me from last upgrades of a desktop (1 GB). Unfortunately I did not try 512 MB (it is not easy to buy such memory).
"Do you think 3A would be enough to power such a system?" -
Yes I think that psu 3A/12V is quite enough: power consumption of my cMP2 (P4 and P24) now is 20W. So the margin of power will be 36W-20W=16W. It is quite good.

 Your post covers much of the optimizations. That will make it much easier for novices like myself. Your willingness to share is most appreciated!

My first build will be with the 32nm tech'. So I don't have the experience of building and optimizing a machine for CMP2 at all.

Can you share any differences in implementing minlogon with the new platform that vary from the old platform procedures?

Thanks for your time and consideration

Julien

 Hi Julien! There are no differences in implementing minlogon with the new platform. I use procedure described here http://www.audioasylum.com/forums/pcaudio/messages/4/40869.html.
Pay attention that there is no section PnP/PCI Configuration in BIOS settings of system board Gigabyte GA-H55M-UD2H and consequently there is no possibility to instal PCI Latency Timer (CLK) - [128] (as on an old platform). So it is necessary to install program PCI LatencyTool, to start it and to install value New Latency for an audiocard: 128 (as is shown in a figure):



All the others optimisations remained practically without changes (except those moments about which I wrote earlier).

Good luck!
Serge.

 I have Gigabyte GA-H55M-UD2H rev. 1.3.
From your screen shot I can see that you are using BIOS vers. F11.
The F11 version (20/08/2010) I D/L from Gigabyte site is slightly different for my revision motherboard.
It has no Spread Spectrum option, no Advanced Chipset Features, no Boot-Up Num Lock.
I hope such options will be implemented soon.

There used to be a hidden menu in the bios, was there?!

ADDENDUM: although I cannot try it right now, the hidden menu is Ctrl + F1
I answered it myself! :-)

 I have replaced picoPSU with the linear PSU as I wanted. But the new system board is not started without delay of signal Power OK (grey wire) (with Pico PSU is OK!). Therefore it was necessary to use a delay circuit.

 I have recently switched to the "new" standard platform:
Gigabyte GA-H55M-UD2H (rev 1.3) + Intel Core i3 32nm + 1GB Kingston DDR3 Value RAM.

Previously, I had AHCI implemented and, going from XP to cMP shell, cMP was taking a while (roughly a minute) to read my 2000 CDs library from HD. On my new platform with IDE selected for SATA Mode in BIOS, such reading takes a lot longer. I therefore would like to switch from IDE to AHCI mode.

I have updated INTEL SATA driver to "sata_irst_32" in XP. After switching to AHCI Mode in bios, however, I still get a BSOD.
Is this happening because I have minlogon?!
If yes, what is the right procedure (reverse and son on)?

Thanks

 I have recently switched to the "new" standard platform:
Gigabyte GA-H55M-UD2H (rev 1.3) + Intel Core i3 32nm + 1GB Kingston DDR3 Value RAM.

I run in a few problems with PCI Latency Tool.

I installed v2.7 and perhaps this was my 1st problem.
I followed Mihaylov's indications from his recent post - http://www.audioasylum.com/forums/pcaudio/messages/7/79286.html - which however are slightly different from cics's post at http://www.audioasylum.com/forums/pcaudio/messages/7/74331.html.

I managed to see my sound card and change (apparently) its latency. However, I never managed to have Latency Tool running under Services. Also, although the new value seemed to "stick" at each restart, my ASIO input latency stayed at 98 all the time.

What is the right installation procedure with BIOS F11?
Which PCI Latency Tool version to install?
As I now have minlogon installed, do I have to reverse it as described in http://www.audioasylum.com/forums/pcaudio/messages/7/74834.html ?

Thank you

 After reversing minlogon, I managed to install PCI Latency Tool 3.1 and I have it appearing in Services. I followed cics' instruction in http://www.audioasylum.com/forums/pcaudio/messages/7/74331.html.

However, with my LynxTWO-B card ASIO input latencies are NOT affected by latency changes at all, as reported by cPlay Diagnostics.
For a 32 sample buffer, I always get 98. Therefore, I have no chance to match ASIO input and output.
Is there anyone who has matched latencies with a LynxTWO-B card on this platform? Or on any other platform for this matter.

Thanks

 Hi Bibo01,

I am in the process of making a cmp2 box with the new hardware.

My old box is what I am typing on, so I am going by memory a bit, but I do remember that I DID have matching latencies on the old box.

I thought I could use my old hdd with all the cmp2 changes, and while I CAN on the new hardware, I will be starting over and probably finish later this week.

I'll let you know what my latencies are when I am done.

Switch from IDE to AHCI with new platform - Recommended!, posted on October 25, 2010 at 08:48:41

 After reversing minlogon, I managed to switch from IDE to AHCI mode on the new Gigabyte GA-H55M-UD2H platform. It was not as simple as I thought, but it is worth it because it makes access to a large Music Library (all its CUE files) a lot faster. On my 2000 CDs library it takes about a minute in AHCI mode, compared to over 5 min in IDE mode.

This is how to make the switch --

After looking on many forums and many BSOD, I found the solution at this link: http://www.neowin.net/forum/topic/457699-enable-ahci-on-intel-chipsets/page15588980114.

There is an AHCI WINDOWS XP PATCH to download. It is a few years old, but with a few changes it works.

Together with an old version of Intel Matrix Storage Manager, in Prepare directory there is a little "INSTALL.CMD" program with the following string:

rundll32.exe setupapi.dll,InstallHinfSection DefaultInstall 132 %~dp0imsm_pre.inf

It refers to "imsm_pre.inf" which one has to "mod" with the right Southbridge code. The new Intel H55 is not part of its list, but from the up-to-date driver I discovered that it is "3B22"

1) Make sure AHCI is not enabled in your BIOS.
2) Open \\PREPARE\IMSM_PRE.inf in Notepad.
3) Replace any instance of XXXX with "3B22".
4) Save the file and close Notepad.
5) Run INSTALL.CMD in PREPARE directory.
6) Exit Windows and reboot.
7) Enable AHCI in your BIOS and save.
8) Start Windows XP, The Found New Hardware wizard will start automatically.

 Thanks for trying.

Actually, I discovered that the large difference between IDE and AHCI depends on the bios setting Integrated Peripherals/SATA Port0-3 Native Mode which it must be "Enabled".

 I have 286 albums with flac tracks on the 2.5" hdd (Hitachi 5K500.B) and scan time of music library during cMP start up is 25 sec. in IDE mode and AHCI mode with "Integrated Peripherals/SATA Port0-3 Native Mode" Enabled and Disabled - equally! The setting "Integrated Peripherals/SATA Port0-3 Native Mode" into "Enabled" in IDE mode lead to next:



...and into "Disabled":



...and "Enabled" or "Disabled" SATA Port0-3 Native Mode in AHCI mode lead to next:



From system board's manual:



About AHCI advantages (translation from russian):
"AHCI mode provides the greatest gain (some times) in cases when some applications simultaneously work with a hard disk. Increase by that more than is more distance between areas with which applications simultaneously work. By operation mainly one application with a hard disk the effect from operation NCQ will be minimum." (http://acerfans.ru/faq/358-tekhnologija-ncq.-stoit-li-vkljuchat-ahci.html)

Thus it is recommended to leave following settings:

 Firstly, let me say that in terms of speed I have to revise my initial position. The scan time of my 2000 CDs music library during cMP start up is ~60 sec. in IDE mode and AHCI mode with "Integrated Peripherals/SATA Port0-3 Native Mode" Enabled and Disabled - equally! The initial difference that I reported was probably due to HD coming out of sleep mode.

Secondly, IRQs in IDE mode and AHCI modes are different from yours.
IDE with "Integrated Peripherals/SATA Port0-3 Native Mode" Disabled:




IDE with "Integrated Peripherals/SATA Port0-3 Native Mode" Enabled:




SATA with "Integrated Peripherals/SATA Port0-3 Native Mode" either Disabled or Enabled:




Therefore, given that I do not have IRQs conflicts like you (my non-onboard USB sockets are just for mouse/keyboard + seldom used service), my personal recommendation is to leave in SATA mode Enabled. :-)

 dear forum,

can anyone explain which parts of a motherboard uses which voltage(es) ?

PCI uses 3.3 V for example for the soundcard and certain other processors/chips do presumably use all individual voltages.

we are in process of putting together a linear PSU and would like to know which certain areas of the motherboard are consuming which part of the P24 ATX connection.

in michailov´s PSU project there is no direct advice of which "ground" connection is part of which power circuit.
or in other words : given we have three linear supplys (3,3V,5V &12V) do they all use the same "ground" ?

how to assemble the P24 ATX connector correctly -that´s the big question.

please help, if you can.

kind regards

 I am building an ATX linear supply following Mihaylov's project.

Although I am sure Mihaylov can add to me, I believe that the P24 supplies all share the same ground.

One word of advice -
The latest Gigabyte MB reccomendation does not need -12V for startup. However, knowing that you employ a LynxTWO-B card like me, this card requires:
+5V 600mA
+12V 500mA
-12V 150mA

Therefore, no need of +3.3V for it, but all 4 linear supplies are required, including -12V. I am also evalueting the possibility of double consecutive stabilization on +12V circuit as well as +5V.

Re. P24 connector, it is possible to make such connector from scratch but you require the right tools to crimp. So, I went to my local computer repair shop that throws away dead ATX PSUs every other day and cannibalized one for P24 and P4 with cables. For device cables+SATA conenctors I had one left (actually a few) from my last PSU which had detachable cables.
Eventually, if needed, the P24 connector is MOLEX 39-01-2240; the P4 connector is MOLEX 39-01-2040. You can search for those numbers at, for ex., RS Online.
Any connector explanation can be found here: http://pinouts.ru/pin_Power.shtml

 "I believe that the P24 supplies all share the same ground" - it's true!
Pay attention on the page 6 from http://www.cicsmemoryplayer.com/index.php?n=CMP.ApdxBAdvanced?action=downloadman&upname=B_Linear_PSU.pdf:
"The terminal block (position 9 in the fig.1) is the center of the PSU’s «ground star». The ground buses from all three circuit boards (are soldered by a thick wire to filtering capacitors of rectifiers – see the position 8 in the fig.1) converge here and diverge to the power consumers."
Bibo, whence you have known that +3.3V is not required for power supply of Lynx Two?

 The no-longer-active and lamented JackWong96 seemed to have the best grasp of how power is used on motherboards. He describes some of that in this post:

http://www.audioasylum.com/cgi/t.mpl?f=pcaudio&m=75904

But noone has yet performed and published a comprehensive survey of all of the voltage consumers on the recommended motherboard(s) AFAIK, sorry.

I do suspect that 3.3v is only being used to power some of the less-critical circuits in the MoBo, but I am not sure if you'll get a good boot without that voltage. Worth a try... Mihaylov, Bibo01, or others, have you tried booting one of these boards with the 3.3v not active? JackWong96's experiments with removing and/or un-powering various peripheral chips did strongly suggest that the board will not be upset if at least some of the non-core chips were not active, so you might get away with this. I do know that with the GA-G31M-S2L mobo, I am only supplying about .3ma on the 3.3v line, so it is lightly used at best. JackWong96's experiments suggested that a number of the uses were non-critical chips (like the DVI to HDMI converters) and removing them and similar chips nearly halved the power consumption on that line.

Then on grounds, as Mihaylov has indicated, all of the grounds connect together at the ATX-24 socket on the motherboard (at least on the Gigabyte boards we are using... I haven't looked at every board out there!). That is also true for each of the multiples of the same voltage rail... for example, all the 5v connections on the ATX-20/24 come together at the socket on the mobo.

One technique I've seen recommended is to pair each voltage line with a corresponding ground line to minimize the radiated noise and magnetic fields. On my supply, I used twisted pairs or braided triples or quads for this. I used a 20-pin plug (see attached picture for a good diagram)



I paired up the following:

- For +5v, I paired up the grounds on pins 16 & 17 with the +5v on pins 19 & 20 into a 4-cross braid. I also paired up the grounds on pins 5 & 15 with the +5v on pins 4 & 6 for a 2nd 4-cross braid.

- For +12v, I paired up the ground on pin 7 with the +12v line on pin 10 as a twisted pair.

- For +3.3v, I combined the +3.3v lines 1, 2, & 11 into one wire, then twisted that with the ground on pin 13.

- For the +5v PWR_OK & +5VSB on pins 8 & 9 respectively, I used the ground on pin 3 with them to make a 3-wire braid.






Of course, feel free to make your own choices for pairing wires up if you decide to do this.

Bibo01, thanks very much for the Molex part numbers. I used a scavenged ATX-20 connector for my 1st supply, but I'd like to do it with a virgin connector for my next. You've made that easier!

BTW, to confirm something I said in my monster Juli@ mod thread awhile back, that soundcard does not use the 3.3v from the motherboard. This doesn't appear to be useful for anyone involved in this sub-thread now, but might be useful to someone else making their own linear supply another time.

Best of luck to you on this. I think you'll find it very rewarding!

Greg in Mississippi

P.S. I've been corresponding separately with another inmate who has posted here very little. He worked up a linear supply for his cMP and it had easily adjustable voltages on the 5v and 12v lines. He played with them and found that lowering them by something in the range of .2v -.4v produced SQ benefits. I know he's been otherwise-occupied and I'll let him tell his story when he can, but based on his experiments and similar accounts others posted here in the past, I tried it and found it worthwhle too.
Everything matters!

 I have known that +3.3V is not required for power supply of Lynx Two directly from Lynx support.
Also, even if one might use analog side of the card only, all three supplies are required.

 Launch "Disk Management" from Control Panel > Administrative Tools > Computer Management and you'll find the option becomes available.

On a full cMP system the above Disk Management is not possible - "The RPC server is unavaiable" - because so many services/options have been stopped.

Cics or anyone else, could you please tell me how to temporary reactivate it in order to set the allocation unit to 64 kB for the music drive?

Thanks

 Connect your hard disk as external (or internal) to any computer (a notebook, a desktop) and format the necessary hard disk partition with any allocation unit. (I use mobile racks both in cMP2 and in a desktop - it is very convenient).

 . . . how to temporary reactivate it [RPC] in order to set the allocation unit to 64 kB for the music drive?

IIRC, as well as enabling RPC, you also need to enable the two Logical Disk Management services. But I wouldn't worry too much if you've formatted the disk in a different way - it'll be fine.

A 64KB sector size makes sense for a music drive (where file sizes are large) but it also makes sense not to lose sleep over it.

 Mihaylov,

Thanks for checking. Dang, it would have been a nice simplification to the linear supplies.

As for the foil-ish things, those are damping materials.

I'm very big on vibration control.

I can't say that I heard any diff from the material on the SATA cable.

And didn't try those caps with and without.

But other cap, case, and heatsink dampings have been very audible. Additional damping on my amps (on the clips that attach the devices to the the heatsinks) was what made B38 preferable to B37 in my system.

The foil-looking stuff is EAR material available from Michael Percy. I also use Dynamat. I generally prefer Dynamat on cases & the EAR mtl on components.

On my linear supply, all the caps, transformers, and rectifiers are damped. Also the structural materials were chosen for vibration control... bamboo mounting structures with brass hardware (no steel hardware anywhere in supply). Bamboo bases were also damped with combo of Dynamat Xtreme & regular.

My Zalman case is also extensively damped, as are my other supplies and the heatsinks on the motherboard. Also my amps, my volume control, and speaker crossovers & structure.

Much more to try, but this has been a fruitful excursion over time.

Must listen to the effect when doing... when I damped the caps in the linear supply, first used Dynamat Xtreme... great clarity and extended & strong bass, but tunefulness was impared. Replaced with EAR damping, very slightly less clarity & bass, but very tuneful by comparison. And I hadn't expected any changes with that damping as the caps are already mounted to the bamboo bases with a resiliant double-stick tape.

Later!

Greg in Mississippi

P.S. If you haven't tried these, I can strongly recommend these two tweaks to your linear supplies:

1. Add another supply for providing the control voltages instead of taking them off the ATX-20/24 +5v.

2. Seperate the AC input to the P4 & peripheral supplies and take them to a separate AC circuit in your listening room as per cics recommendations.
Everything matters!

 Mihaylov,

Very welcome.

On that 1st tweak, the control voltages are the +5v for the +5VSB & the PWR_ON signaling.

When I first setup my linear supply, I saw that the motherboard didn't appear to need those voltages (along with the -12v) after it had booted, so I supplied them with a battery and turned them off after boot.

When I was troubleshooting why my system would not stay running, I decided to try to make those voltages permanent. I put in small AC transformers along with diodes, filter caps, and regulators for both the +5v control voltages and the -12v. Doing this fixed the issue with it shutting off randomly... and after we realized that the -12v was not needed for anything but the GA-G31M-ES2L board, I pulled that supply out.

Later, I thought it might sound better to supply the +5VSB & PWR_ON from the main +5v ATX-20/24 supply due to a simpler setup and grounding. When I wired that up, I lost some clarity and individualization of sounds. So I've gone back to the separate supply for _5VSB & PWR_ON.

The difference, while not huge, was very definite & positive.

BTW, I didn't notice any difference between supplying the +5v control voltages from the small AC supply or a battery, but the battery was only a 9v battery, so a better battery might be a different matter.

This leaves me with 5 separate AC tranformers in my linear ATX-20/24 & P4 supplies! Gotta lotta iron!

Later!

Greg in Mississippi



P.S. On the motherboard, the control voltages are separate from the main +5v ATX-20/24 line. When I lowered my +5v down to +4.6v or so, it didn't cross over to the +5VSB & PWR_ON.
Everything matters!

 Far be it for me to act like an expert but I think this tweak increases the time between usb poling so that it happens less frequently. Happening less frequently reduces noise and lowers the frequency of that noise. I believe the 5ms is the only alternative to the stock timing.

Because, except for the default, that's the only available setting :>)

I faffed about for hours trying to make it longer but failed. For a discussion, see link (though I'm afraid the noise level on the thread was pretty high). If you do try it, please report back.

 Do you have any experience with nLite?

I do. As far as cMP^2 was concerned, my experience was much like yours - it was a time-wasting disaster.

The goal with cMP is to minimise the memory footprint, not HDD space: nLite is of limited use in achieving that. Have you a special need for a minimal install?

 Hi,

If you have purchased and are using the Gigabyte GA-H55M-UD2H, can you let me know if the board worked well out of the box or if you have had problems? I was about to purchase one but the reviews on New Egg seem to suggest its a fairly low quality board.

Thanks,
Alan

 This is just my own experience.
I had Gigabyte GA-H55M-UD2H v1.3 which apart from a different LAN chipset I suppose it's newer than v1.0.

Out of the box MB worked really well for a week. I then had to reinstall to partition differently. After the reinstall I realized I had slightly higher DPC latency figures and strangely no Power Saving. After the 4th reinstall the mobo went dead and I had to RMA it. I am now waiting for replacement with the same MB.

 I was confused by the board asking me which HDD "system" (I really have no idea what it does) I wanted - I inadvertently chose AHCI and could not get it to work which is no surprise (no) but it was quite confusing to me.

I think I had to re-install WINDOWS, it was awhile ago, and all was fine after that.

I find my set-up, which is to cics's specification and is only used for music purposes, will only allow a CPU voltage of .7 volt. Anything less and it freezes up and requires BIOS battery removal to start again.

I do find that little things will cause boot failure and it returns to a bit over 1 volt which then requires BIOS battery removal. But the neat thing is the first screen I see after restart gives me the default choice of PREVIOUS GOOD VERSION, or something like that and when it comes up to cPLAY and I check CPUZ the voltage is correct. All of the BIOS settings are set to cics specification. So, it is a bit of a pain but one does not have to re-do all of the BIOS setting.

Luckily my box is homemade and allows quick access to the battery.

Other than that the board performs very well and DOES sound better than the previous generation MB and CPU.

As far as quality, the things looks very high quality. I have read the NEWEGG reviews also which are certainly not ALL negative.

If you like cics's approach you should take your chances and get one. I think it far more likely you will NOT have MB failure.

Bye.

 After getting through the install the PCI bus crapped out. Board was RMA,ed under warranty listening to it right now. Excellent playback! My CPU and Video voltages are a little higher than recommended. My thought do those two changes last. T.
No worries!

 Does someone already try one the last MSB dac IV with Cmp Cplay ?

We often talk about DCS dac and I'm happy with my delius. But reading on Internet make me think that MSB product are more than serious and have made a lot of progress since their linkdac III AND it's could be one of the most serious company about dac.
Have a look at their incredible dac IV (costing up to 30.000 $!). Would be curious to heard it with the right amplifier (Soulution 700 ?) and speaker (Magico ?) with CICS comuter.


MSB has a good paper on jiter

 It's refreshing to see MSB doing good work on jitter. They're the first manufacturer I've seen that understands how to measure jitter distortion. MSB's jitter paper is a good read however, their 2ps jitter level is very optimistic:



Based on my calculations, periodic jitter (on 11.025kHz input) will yield side band distortion levels of ~-149db and not the -137dbrms (-134db actual) shown in their plots. At this indicated level, jitter is ~12ps. Overall jitter measurement requires measuring all jitter spectra (at many different levels) and express the overall jitter as RSS (Root Sum of Squares). Periodic jitter doesn't occur at a given jitter frequency but over a wide spectrum. Hence, its always good to have a PLL based XO design to remove jitter at high frequencies.

In my experience, transports have far larger impact on jitter distortion at DAC outputs. The DAC is "tethered" to the transport. So you better off upgrading your cMP² power supplies (to linear) instead of a new DAC. My reason for switching to dCS was for 192k input (as my AA Prestige SE only does 96k). They are both excellent DACs.

Anyway, I'm looking to upgrading my speakers... any recommendations?

 Hi Cics,

Thank you for putting the ‘not so white’ paper from MSB into perspective.

* On power supply.
I’m glad you mention use of linear PSU’s.
Improving the power supply (in my setup and my situation) yielded the most sound quality improvement.
May be on your website, you should encourage people somewhat more, to improve the power supply of a cMP setup.

For instance: you encourage the use of 2 ATX PSU’s.
But what about encouraging people too use 2 linear driven Pico’s?
I know: Pico’s are also ‘switchers’. But it’s my feeling that 2 switching Pico’s give better sound quality, than using 2 (switching) ATX PSU’s. I don’t know why that is. It’s just my impression from listening.

* Suggestion for new speakers.
It will not come as a big surprise: I would recommend too have a good listen too active speakers. I think the whole concept of active speakers is a much better approach. Technically as well as economically. Have a good look at manufacturers like: ATC, PMC, Quested, Geithain, ect

 About the "network" input of MSB dac : I'm questionning myself about the msbnetwork as they are able to upgrade many dvd drive with this, I'm thinking about the upgrade of this on a sound card, I'm quite sure they are able to do that. This would permit to output up to 392 khz from computer to the dac in a very good way.

About speaker, I'm a big fan of monitor speaker, I have Proac response 1 Sc. For me if would change I would try the response D2 and if more money the mini magico.

Have you ever hear of the new amplier Devialet D-premier, I would dream to try it with a cmp/cplay computer. They are a lot of very good talk and review. It accept direct digital connection as it's a combination of class D and class A, but in review I have read, they feeding it with what I will say bad digital link. On review is done with the LINN DS accurate and the result is wonderfull.

 On the speaker question I can only suggest Quad ESL of any flavour.

Mine are One Thing Audio reconditioned/modified ESL63, mounted off the floor on sand boxes, driven by a Quad 909. They are VERY transparent and your reductions in PC jitter come through very clearly but most importantly (to my ears) they are true to the music...

They are also robust enough to survive my Labrador !!!

best wishes and keep up the good work

 I agree that really good electrostatic speakers are very revealing of subtleties in front end changes. I have Martin Logan Monolith III's which I recommend but I also wholeheartedly agree that Quads will not disappoint.
Estats are very good at revealing transient performance.

 I know this, at this moment, does not directly relate to cMP and computers but I think these things are worth a mention.

I got four of them yesterday and attached them to the two (each side) compression drivers in my speaker system and was very impressed what do for them. The TAD's are renowned for being agressive so one is always looking for ways to "smooth" them, which I thought I had made some strides. These things added yet another level of goodness to these things. No loss of detail but an added level of refinement.

There has been much said about these and the earliest adopter I know is Theo B.. I gave him a hard time about not bringing these things up. I decided after hearing them (got them yesterday) to say something.

They are attached to the ground side of your seakers or your electronics on the signal side.

I am going to get some more and see if there is a place for them on JULI@ and my DAC.

As with all tweaks: they may seem insane but what they give cannot be got any other way.

 fellow inmates,

I was having a little lecture of a very respectable amplifier designer the other day, and he told me that a common grounding is absolutely essential for ultimate performance.
-not only common ground, he emphasized, but the very same point of grounding !

now, when I think about it, that seem to add to the theory of why separate power circuits in the cMP mashine are so convincing.
it could also explain in part, why some power phasing can be heard and others can´t.

can someone fill in on this ?

(stay grounded however :-))

kind regards

 Available now from Bryston is the BDP-1, a high resolution digital music player.

Looking at these descriptions:

* Linux operating system optimized to provide the highest quality audio
performance.
* Industrial quality motherboard uses only a small fraction of its
computing power to optimize sonic performance.
* Utilizes Bryston-modified top quality soundcard.

it appears that this player has a similarity to our very own cMP player.

Anyone got a chance to listen to this player? Am wondering how this would compare to a cMP rig.

 Have a listen to the Harbeth's. I have the 25Anniversary SHL5. The anniversary editions have slightly better matching and other internal upgrades. If your room size is up to it the 40.1 is phenomenal sounding though I have never heard them in my own setup. I power mine with an 18 w PP 300b, a 30 watt PP KT88 and a 50watt 2505 depending on my mood. I no longer use a dac I use the L22 cardas breakout analog out. That way I don't have any issues with hi rez. I never really go much louder than 12:00 very refined detail with excellent imaging. FWIW T.
No worries!

 Many thanks to all of you for the speaker recommendations. Its been 5+ years with my Nova Utopia Be speakers.

I agree with powered speakers - they're great value and deliver excellent results. My mini setup (now disconnected) is based on JMLab's Solo 6 - it's the only version that uses analogue inputs directly - all others convert to digital... Electrostatic speakers (QUAD, ML) is something I should look into in future.

After some back and forth with a few dealers, I finally settled on Sonus Faber's Stradivari. My first choice was Magico's new Q5 but the deal made poor economic sense (i.e. I refuse to overpay). Anyway I'm very glad it turned out this way as the Strads are showing magnificent potential. Overall balance is very very good. Still its early days (only a few hours break-in)... Also, SF is under new ownership and their new direction (Fenice) is not to my taste at all. I auditioned Wilson Audio's Alexandria just to get a reference of sorts. The Strads certainly delivers (just not at the very bottom which is not a priority for me). I think the Strads are Franco Serblin's finest creation (Franco is no longer at SF). Oh that glorious midrange performance is revealing and very addictive!

 Mark,

May be on your website, you should encourage people somewhat more, to improve the power supply of a cMP setup.

I agree totally. Though truth be told i really want to do this on my cmp2 rig. But I certainly havent seen anything like a cmp2 type project for this. I mean anykind of step by step instructions.

Just fabulous picts of diy efforts and mentions of a vellman supply, which I dont get how that would power everything.

And why the need for the pico at all? Why cant one just wire up a 12 v supply?

See, I need some kind of brainless how to.

Anyone know of one or want to write one??

 Hi Cics,

Congratulations on your SF Stradivarius purchase. Very beautiful design and very well crafted. Also with very good driver units. Coincidence: before I switched too Klein & Hummel O300 I used their Grand Piano’s. I like the SF sound very much. They matched very well with my NAIM NAP 250 / NAC82 setup.

I never heard of Magico and there Q5’s before. But studying their website I like their innovative approach and designs. But at $ 89.000,- . Omphh.. I have to work for that one whole year. :-S

Enjoy your new SF Stradivarius !

 Hi
after a complex semilinear approach now I'm planning to assemble a full linear PSU system.
My project was thinked around the AMB lab Sigma 11 power supply (http://www.amb.org/audio/sigma11/) in a Miahylov fashion.
Studying about problems, I need some help:
1)The PSU will be external so I need a long run of cable. How can I try to reject various interferences: Shielded cable? Twisted?How twisted?
2) In the Miahylov project ground star seems to me formed by each negative cable coming from each different power supply. From the star, or better to the star, arrive all the ground cables departing from P 24. In the Miahylov PSU I can see one large cable that near to the connector go to join with all cables coming from the P 24 connector. Is this another "floating ground star"? Or It could be better to arrive to the ground star inside the external PSU with each single cable?
3)Where (if i must) I'll connect the PWR_Ok grey cable?
4)where (if I must)I'll connect the PS_ON# geen cable?
5)+5VSB PSU must be always turn on or could start with the others PSU together?
6) always In the Miahylov project, I can see a relais near a little printed board. How is the sequence of turn on each PSU? How is connected the relais?
It could be possible that these arguments was explained yet but my research was ineffective
THX a lot to everyone could help me
THX a lot to bibo01 for Italian cMP2 site and forum: great job, Bravo!
Daniele
PS: my actual system ( GB H55MUSB3+i3 540) is feeded by:
A) Seasonic x650 ATX PSU: P 4( via a run of 6000 mF of Silmic II)+ SSD+CD/DVD/BR+ external HDD
B) Picopsu 150 XT: P24 only
C) Peaktech 6080 +12V: picopsu + sound board Asus Xonar ( 2,45A in music playback. If you connect P4 too, consumption rise to 2,7-2,8A)
D) Peaktech 6080 +5V: Sound board Asus Xonar + USB (1,5A in music playback)
Four switch to turn on and the Peaktech +12 become very hot after an hour, but sound is gorgeous

Its a poor pricing decision given that Strads are ~$45k. The same can be said of Pioneer's TAD-R1 ($60k+) which was on my list as well. I haven't heard a speaker that brings it all together as well as the Strads - this includes Wilson's Alexandria at ~$150k. Strads are that good (after a few days break-in), they're easy to drive (a pleasant surprise) and thoroughly engaging!

Its amazing how SF achieved this level of performance without using Be drivers. Those silk ring-radiating tweeters are stunning and easily surpasses what I experienced on my previous JMLab's Be version.

 Hi!
1. "The PSU will be external" - It's the correct approach.
"How can I try to reject various interferences" - I think that no interferences will exist and will enough apply a qualitative power (acoustic) cable, for example, the such http://www.soundstringcable.com/audio_cables_cords/In-Wall%20Cables/tricormaxial_UL-bulk_speaker-cable.html together with Neutrik connectors http://www.neutrik.com/fl/en/audio/204_42012003/XX_Series_productlist.aspx and http://www.neutrik.com/fl/en/audio/204_293581/DL_Series_productlist.aspx.















2. Download the document added with two schemes once again. There can be you receive answers to some questions.
3. PSU -12V it not to be necessary for your system board most likely.

Would this document replace the current one available for download on cMP² site?

Is there a way to manufacture these linear supplies in limited quantities? How much seed capital would be needed? Paul Heynes seems to offer something but at very high cost.

"Sticker removed" does not sound that good to me but it should not matter. Can the OCZ 512RAM be bought somewhere ATM? :)

Finally on the sound quality gains from having 512 instead of 1024MB, does the lower size has also lower cache Latencies or is it solely because of less power consumption? Many thanks.

 IMHO, a cleaner solution for any ATX case would be:

- an external box with the 3 PSUs
- 3 ext. cables
- a metal plate with connectors, for PC back in place of ATX PS
- 3 internal cables for P24, P4 and Peripherals.

This is how I am building it!

 

When finished, could you post some pics?, posted on December 12, 2010 at 05:36:27

 Hi BiBo01,

I’m considering such solution too.

If you have finished them, could you please post some pics here on the forum or on Picasa for some inspiration too others who also consider a separate enclosure for there PSU’s?

No need to ask :)
