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.

 Hey Theob,

It has happened many times but always when I have done some bios changes. I finally got it to 840mhz and it was working like a champ. I have enough time with this rig to have a really good sense of when it is stable. Once it is, it is.

But I cant fathom why changing a pc could affect anything. Just dont get it.

I am lucky though as I havent received the "I dont recognize your soundcard" error.

 Well when it doesn't recognize my soundcard cplay just won't play and even after reboot there is 'no-esi' icon in lower right of screen. When that happens I need to shut down, pull out the card and re-insert then reboot then I'm ok. I don't know why changing power cords, power conditioners and other stuff causes the pc to reset host clock control but it does. I'm afraid I also have a borderline stability problem in my setup because I can never get quite all the way down to 140 hcc. I had it for a long time @ 143 but I would occaionally get the system to go crazy (loss of screen and loud noise into my system) so I eventually migrated to 147 hcc at which I can run 192 with no issues. S o who knows. Right now I am stable (he says fingers crossed).

 I can get 140, but the GTLREF setting ALWAYS hoses things. I HAVE to leave that at the default. It is weird.

 Because we're discussing it I'm trying 145 hcc right now. I hate that I can hear the improvement vs 147. I will try to migrate back to 140 while listening to only 44 khz.

 I just posted this in cPlay, I was reset to 1.6. I find for me I have to leave the CPU VID at .85000 any lower and I have to do a Bios reset. I am using the ES2LT.
No worries!

 Hey I have the ESL2 and have gotten it down to .75v but not at 840. Currently at .83 and 840mhz, though I have to see if it boots from cold.

I too have had things not sound right, only to find that it had reset to 1.6.

Designed for portability, it closes into a very small package... at which time it is off and not transmitting. But when unfolded, it is a nice shape that works either on a surface or held as a remote.

It does have three buttons plus a wheel, which provides the basic cMP & cPlay functionality.

And it does work from 15'-20' away.

 Planning to change to "LGA1156"?

You're ahead of me on this new hardware. From manuals, here's the advanced settings (all else as per current documentation - be sure to disable EIST).

    MB Intelligent Twaker (MIT)

  1. Advanced Frequency Settings



    • CPU Clock Ratio to 6
    • Base Clock(BCLK) Control to Enable
    • BCLK Frequency to 140 (this should give lowest CPU freq of 840MHz) - you may need to use higher numbers until hw beds-in.
    • System Memory Multiplier to 2
    • CPU Clock Drive to lowest possible (default is 800mV)
    • CPU Clock Skew remains at 0ps (manual is silent but this seems to control Spread Spectrum)


  2. Advanced CPU Core Features



    Test 2 scenarios:

      Scenario 1 - uses both CPU cores but disables HT
    • CPU Multi-Threading to Disable
    • Disable:
      • CPU Enhanced Halt (C1E)
      • C3/C6/C7 State Support
      • CPU Thermal Monitor
      • CPU EIST Function
      • Bi-Directional PROCHOT



      Scenario 2 - this is preferred as we use only one core but enable HT (I was planning to do this via XP but GB was very kind to include it in BIOS). This is a big advantage as we only use one physical core!
    • CPU Cores Enabled to 1
    • CPU Multi-Threading to Enable
    • Disable:
      • CPU Enhanced Halt (C1E)
      • C3/C6/C7 State Support
      • CPU Thermal Monitor
      • CPU EIST Function
      • Bi-Directional PROCHOT


  3. Advanced Memory Settings



    • System Memory Multiplier to 2 (or lowest allowed)
    • Performance Enhance to Standard


  4. Advanced Voltage Settings



    • CPU Vcore to lowest stable (as we do with current hw) - start with 0.85000V
    • Dynamic Vcore (DVID) to Disable (if possible)
    • QPI/Vtt Voltage to lowest possible
    • PCH Core to lowest possible
    • CPU PLL to lowest possible


  5. Miscellaneous Settings



    • Isochronous Support to Enable (or Disable - test this)
    • Virtualization Technology to Disable


This is an impressive range of BIOS options! GB have created something very special here and allows for maximising audio performance.

Let us know of the progress you making. Many thanks!

i have changed to 1156 for 2 weeks ago...
upgrade from s939 amd to this....
i did ask whether does it sound different whether upgrade my gear to i3.. yes.. it is much less noise and more musical..

***Gigabyte F5 bios allows you to turn off the clock spectrum***.. hehe
cics, i did try your suggested settings.. hmm yes it works fine..
but i know it can be bit more better. i m figuring it out.. hehe

 In an effort to reduce onerous administration, a new dedicated website has been born. This means everything is consolidated into one easy site (from 4 separate sites). Also there's more flexibility and removes new limitations/conditions imposed by SourceForge.




www.cicsMemoryPlayer.com


Current sites (including SourceForge ones) will be shortly discontinued or alternatively re-directed to this new site that will receive all future updates. Special thanks to SourceForge in providing an excellent platform. I'm sure without SourceForge, cMP² would not have forged so far ahead.

 Thanks for sharing. Looks like some interesting options can be selected in that bios.

Did I see that right though that the temps were 70c for the cpu and 50c overall?

That seems awfully high compared to the under 30c temps I get in my box (after hours of play at 192k)

What accounts for those high temps???

And IIRC one still had to enable ide if one has a sata drive, but in your shots ide is disabled. Are you using a sata drive and is that a difference with the new mobos?

Relax - it's a known "false positive" that rears its head here at more or less regular intervals. There are no viruses in any of the cMP^2 modules.

 Why is your RAM set to operate at 800MHz - I see Base clock is 100MHz with RAM mulitplier at 8x. Does BIOS offer anything lower?

@DR - CPU temp shows "- 70°C" and system temp is at "52°C".

@lga775 - please use RealTenp for another measure. Also is the CPU heatsink cool to the touch? If so then you could just remove the fan entirely. I'm hoping this works so we don't have to buy a fancy heatsink. CPU temp can run hot (Intel spec there CPUs to run safely up to ~70°C - will check i3 530). What RAM size is used? What CPU load are you getting at 192k output?

Will be ordering my Core i3 in a few days (waiting for UD2 mobo).

so i try out 800mhz with latencies overclocked yet, it sounds better.

for temperature issue, through my monitoring, during normal playback with stock fan it is 30c but if i off the fan it is 70c, through my experience 70c is no harm for a cpu to operate for that temperature in a long period manner. tats all because i have no extra budget for a high performance fanless cpu heatsink cooler.

The most bottleneck is that i still cant figure out how to run 176 or 192 sampling with spdif without crackling sound..

i always prefers 88.2 and 96, my desire of sampling 176.4khz.
i had tried winxp x86, win7 x64, and winxp x64, my personal opinion winxp 64bit offers a better transparency of music. so i will stay at winxp 64bit.
win7 64bit sucked in music.
i hope someone could help me to solve that issue.

Thanks alot as we are DIYer. haha

Wav files, posted on March 31, 2010 at 05:57:15

Hi all,

as I am a newbie to cMP² I have a problem I cannot solve:

I've installed cPlay as well as cMP, in the Pth file I've defined that cPlay should play Wav files, because I have a hdd with lots of cd's. After adding folders to cMP I get the message "No disc found, please rip or add new folders". Is it necessary to have cue sheets for Wav files, too? Could missing cue sheets be the reason for not finding the folders? I tried to rip a cd including cue sheets with EAC, it also did not work.

I hope someone could help me.

Regards from Berlin, Germany

Intel Atom processor - could this be an alternative option?, posted on March 31, 2010 at 06:15:48

 Intel's Atom CPUs are very attractive due to their low power consumption. It has been successfully used via the Fit-PC2 (headless option). There are however two significant downsides:

  1. Does not support SSE4.1 instruction set which is preferred.
  2. Has a maximum of 1MB L2 cache. This means SRC@145db SNR cannot be done.


Intel recently announced Atom D510 CPU which Gigabyte offers as the mini-ITX GA-D510UD mobo. This is significant in that the Atom D510 offers built-in graphics and therefore allows mobo vendors to utilise Intel's latest NM10 chipset (TDP of just 2.5W)! This mobo should consume ~15 watts but Gigabyte does offer options to lower voltage and frequency making this mobo/CPU the most power efficient one. Aside: previous Atom based mobos used power hungry chipsets (Intel 945GC + southbridge).

Should upsampling to 192k @145db not be a requirement this hardware may provide excellent results! There is a tradeoff in that SSE4 cannot be used. It nevertheless remains an excellent option worthy of further investigation...

 Have you add the music folders to the library in cMP set up?

 

RE: Wav files, posted on March 31, 2010 at 08:05:46

Yes, I've added it to the library in cMP setup and finished by clicking the OK button. Then in the cMP window the message "no disc..." is shown.

When I play .wav files in cPlay without cMP music is played.

I don't know whether it is missing cue sheets or another problem at that point. As written I tried EAC and it also didn't work.

 cMP will only process .cue files. If you don't have these setup for your wav files, see here for a quick way to create them.

Thanks cics,

now it runs (and sounds good without any optimisation). I tried the cue sheet creators yesterday at the dedicated pc and they all did not run. Stupid beginner's mistake: Java was not installed on that machine, I was throwing it away some weeks ago when I started to remove not needed software.... ;-)

Now I could manage it and so I could enjoy the first two pieces of music.

It really sounds good without starting to optimize. Before building a cMP² machine I want to try to get as close as possible with a laptop to see if this could be a way to me. I use the very good Aqvox USB ASIO driver, a good USB cable and separate USB-low-noise-power-supply, also by Aqvox.

Thanks for the feedback on my question - when I ran the Intel D945GSEJT mobo the pwr consumption was ~12w while using cPlay upsampled to 96khz (I am using a SSD and no fans). I did not have a chance to thrift the bios or windows to lower the consumption even further.

I will be trying the gigabyte D510 with modifications shortly to see how it compares.

Thanks for all the info that is available.

 Hi,
I have a new E-MU 1212M PCI sound card. I want to install its driver to my full modified cMP2 PC (with AOB). How can I install driver?

I was try to install but failed; I think, because of some stoped Windows Services.

How can I install drivers for 1212M.

I find that restarting the Windows Installer service is usually enough. (It can be turned off again later.)

 I actived Windows Installer service, but I got this messege:

"Setup is unable to detect a supported product on your system.
Setup will exit."

I also set this services to Automatic:

- Event Log
- Cryptographic Services
- Windows Audio
- WMI

But setup is not completed again.

What can I do about this?

Help please...

 Hi Cics,
Thank you for your answer. But The setup is failed again. I set all Windows services to Automatic. The system give same message. Setup can't complete.

What can I do as solution this problem? I don't want to install new Windows and to do all AOB modification again. Its takes so much time for me.

 The only other thing that would cause this is Minlogon. If you have done so then you must reverse it, i.e. go back to Winlogon & undo registry entry.

Problems with cMP shell, posted on April 5, 2010 at 02:40:49
tom_on_wheels


 
Hi all,

I am trying if cMP² could beat my actual setup without building a new machine firstly. Actually I use an Acer laptop with Windows XP Professional, Intel Mobile Core 2 Duo T5800, 2 GB DDR2 RAM, AQVOX USB ASIO driver and AQVOX' USB low-noise-powersupply into a tweaked PS Audio DL III. Player is iTunes which I find very comfortable. In a shootout my setup has beaten a combination of Lindemann cd player and Weiss Minerva DAC.

First try of cMP² was promising, but I can't get on because of two problems:

- When I click on "Explorer" in the cMP shell nothing happens (pc goes to a waiting status and cannot be reanimated)

- In cMP mode clicking on an album cPlay does not open and pc goes to a waiting status and cannot be reanimated. In XP mode it works.

This is my .pth text:


RIPPER #M "c:\Programme\exact audio copy\EAC.exe"
CUE_PLAYER #N "c:\Programme\cics play\cicsplay.exe" %C
LIBRARY_MANAGER "c:\WINDOWS\explorer.exe"
OSK "c:\Programme\cics memory player\ahkosk.exe"
PROCESS_EXPLORER "c:\Programme\process explorer\procexp.exe" /p:n
EXPLORER_KILL "c:\windows\system32\taskkill.exe" /F /IM explorer.exe
TOUCH_SCREEN "c:\Programme\touchkit\touchkit.exe"
PREP_PLAYER
REFRESH #N "c:\Programme\CPU-Z\cpuz.exe"

Does anyone have a clou what to do?

Furthermore I have another question. I have a fanless Foxconn ITX board with Intel Atom 230 and a tiny hi-fi device like designed case, but no HDD yet. If I would be satisfied with cMP² would it be worth to go on with this mobo to get good results?

Regards
Tom

 I didn't succeed to install 1212M's driver setup; so, I installed a new clean WinXP SP2. Now, there is no problem to install 1212M driver.
But, there is some note about 1212M sound card here:
http://www.cicsmemoryplayer.com/index.php?n=CPlay.Guide

"This soundcard offers poor latency of 2ms (at any sample rate), preferred buffer latency doesn’t match output latency and no hardware optimization supported. Note that if you have an EMU card installed, do NOT disable it (in device manager) as this causes instability (as drivers remain operational)!"

What can I do about this?

When I listening music form unbalanced analog output, there is some crackling like "click, click" sound. What can I do about this?

It's not clear if you are running in "cMP Mode" - your problem is a known issue when running in "XP Mode". See:

http://www.cicsmemoryplayer.com/index.php?n=CMP.11CMPShell

and note (scrolling down to "Chapter 11"):

http://www.cicsmemoryplayer.com/index.php?n=CMP.Headless

In short, if you haven't done so already, click on "cMP Mode" in cMP's Settings dialogue, step through the messages and re-boot. (To revert, repeat but click on "XPMode" instead.)

In "cMP Mode", (File) Explorer works just fine - I use it daily. If you are already using "cMP Mode", shout.

@Dave Thanks for your answer.

I did not try Explorer in cMP mode because it did not work in XP mode. I now tried it in cMP mode and it worked. After closing the explorer I clicked on an album and - surprise - cPlay started to play. I did not change anything and I have tried to fix that for two days.

It sounds good, but I can remark two or three little dropouts per track.

 . . . two or three little dropouts per track.

Glad it's working but you should not be getting any drop-outs.

However, cMP^2 was always intended for - and is undeniably at its best with - a dedicated computer or at least a dedicated OS install.

Have you done the optimisations described in Chapter 7 of the web site write-up (the one called, surprisingly, "Optimisations")? Have you disabled any firewall or AV software? And so on. Unless you have, I wouldn't worry about dropouts for now - they are unlikely to persist in a dedicated setup. Are you using cPlay to "upsample"? If so, try turning it off. Might tell you something.

Would it be worth to go on with [an Atom 230] mobo?

I use a single-core Atom mobo (Fit-PC2, 1.1 GHz), no upsampling. With a USB DAC, it sounds much better than the recommended Biostar and Gigabyte motherboards ever did.

As a test, I find I can downsample from 96 to 44.1 KHz but not from 192 KHz. That suggests that your Foxconn board would work fine with 44.1 KHz material provided you don't upsample it and that hi-res data should also be fine. If you upsample, YMMV.

Bear in mind that cPlay is optimised for the SSE4 instructions set while the Atom supports only SSSE3 instructions. Thus, it follows that I don't know what I'm missing but, I suspect, not that much.

Given the price of a 500 MB 2.5" HDD these days, I can confidently recommend trying your Foxconn board with cMP^2 provided you can live with the above limitations. I can.

HTH

Hi to all!
I and my friend have built audio transports cMP2 advanced. We are very happy with sound quality. My friend's cMP2 has turned out more uncompromising.
- OS - Windows XP SP2 Pro,
- Case Zalman HD160XT Plus
- Processor Intel E7400,
- Processor cooler Thermalright SI128SE (without the fan),
- System board Gigabyte GA-G31M-ЕS2L,
- Memory Kingston HyperX 1GB,
- PS completely linear with a separate supply (up to the toroidal transformer) for the processor (socket P4 +12 V), for system board (socket P24 - here a separate supply for each power bus: +3.3 V, +5 V, +12 V and -12 V up to a transformer winding), for a sound card +5 V, for a hdd and lcd screen
- HDD (OS and audiofiles) SSD 500 Gb SATA-II OCZ Colossus Series,
- Sound card ESI Juli (the digital part is used only, analogue part is disconnected) with external precision clock LClock XO 3 on frequency 24,5760 MHz, BNC socket (spdif out) and additional filtering capacitors Elna Cerafine,
-Turning off lcd screen by means of the big knob on the forward panel cases (button) and a small board in psu.

I used the alternative decision of PSU is the so-called hybrid supply, which basis PicoPSU 120, providing all necessary voltages for socket P24 (P20) from entrance voltage +12 V.

All photos can be looked in My gallery.

Many thanks cics and to all participants of this forum for project development cMP2!

 Firstly, Mihaylov (and friend) congratulations on your magnificent implementations!

This is a very elegant linear PSU (4 toroidal transformers), 270º view:



Questions:

  1. Would this model be the "uncompromising" (i.e. better sound) then the silver one built using hybrid PS?

  2. How exactly did you connect P20/P24 using this setup? Another picture?

  3. How do you start the mobo?

  4. Can this be packaged into a normal ATX PSU frame (note length is very flexible)? I think there's a handsome market for such a high quality PSU offering at least 2 AC inputs (P24 & all else).

  5. Unrelated to PSU: can you elaborate more on the XO used for Juli@?

 EMU drivers are difficult to work with. I found with my 1212M, I had to do a new build to remove the installation! I use it on my dev PC.

Unfortunately there's nothing one can do about its poor 2ms latency performance (quite possibly due to its excessive bloat). One thing you could try is something that carcass93 suggested (unfortunately I don't have a link). As I recall, you need to disable some of its hidden devices that are installed (device manager > show hidden devices > ... be prepared for a long list). Try this search.

As to crackling I too had that - try rebooting and/or using a larger buffer/latency.

1. Unfortunately there was no possibility to compare these two cMP2 directly yet. (About testing cMP2 later)
2. Connector P24: pins 1,2,12,13: +3.3 V; pins 4,6,8,9,21,22,23: +5 V; pin 10,11: +12 V; pin 14: -12V; pins 3,5,7,15,17,18,19,24: ground. I have placed two more photos in My gallery.
3. Switch on the mains switch on the zalman's rear panel (see IMG_0628_ in My gallery), push the power button on the zalman's front panel, that's all!
4. No, imho. Because the linear psu has low efficiency in comparison with the switched-mode psu and produce a lot of heat, hence it requires adequate cooling.
5. Yes.

 Would you please be so kind to give us the "shopping list" for your P24 and P4 PSUs?

Also - I am not sure if cics was reffering to that in his question - there is a particular switching on sequence for motherboard and cpu. How did you deal with that?

Could you please let us know about your listening experience with this system, perhaps compared to another cMP2 system you may have had before.

Thanks a lot and congratulations again!

 Unfortunately now there is no time to answer all questions (I will try to make it during week-end).
About "particular switching on sequence for motherboard and cpu". All voltages on P24 and P4 are supplyed simultaneously by switching on the mains switch on the rear panel of the case (see previous my message, item 3).

Here is the sound test of cMP2.(Excuse me for probably bad English)

Сontrol sound section:
- A control source of a sound: cd transport CEC TL5100 (thoroughly upgraded in a power supply: two toroidal transformers, some voltage stabilizers are added, electrolytic capacitors are replaced with capacitors Black Gate of different series, established the copper screens separating psu, the mechanism, the display and the main board from each other)
- DAC: Musical Fidelity A3.24 (output capacitors are replaced with BG NX)
- Integrated push-pull tube amplifier ART AUDIO LAB m25 (Tula, Russia) (the absolute upgrade is made: external psu on two kenotrons, supplying input and output cascades from separate windings of the transformer; wiring of an anode supply and input circuits of the amplifier by silver wire Jensen; all sockets WBT; a regulator of loudness ALPS Blue Velvet; capacitors BG, Jensen, Elna Cerafine; resistors in grids of input tubes Riken Ohm; four-stage adjustment of feedback depth is made)
- Loudspeakers: Klipsch La Scala 2 (a small upgrade: all "automobile" demountable connections in internal wiring are replaced with solderings)
- Cables: power: self-made, made of an inexpensive acoustic cable; digital coaxial: Supra Trico 1.0m (BNC - BNC); interconnect: Ortofon Reference 8N-1m; acoustic: Nordost Blue Heaven - 2m.
- cMP2: "black case" configuration but with hdd 1000ГБ Western Digital Caviar Green

1. Sounding сМР2 with computer psu (Antec EarthWatts EA 430W)
Sound is dry, etched that is called with the "sand", abounding with the false detailed elaboration distracting from perception of a musical material. A sound is superficial, as though deprived of density. On difficult fragments of products of classical music sounding frequently formal, laid-back. An involvement into listening is low, in a consequence of that listening classical music is simply uninteresting. As a whole the control source beat сМР2 though lost to the last on some parametres, such as the resolution and depth of a stage.

2. Sounding сМР2 with completely linear psu.
The occurred changes in a sound can be characterised as critical: the sound from the cheap ("computer") has changed in the costly, close to an analogue source on character of sounding . Sounding became more dense, perceived, the "roughness" and "sand" have practically disappeared, was showed timbre saturation, "beauty" of music. The involvement into listening has considerably raised, the perception of a musical material was facilitated. At high levels of loudness fatigue from long listening is small.

3. Sounding сМР2 with completely linear psu and a precision external clock.
The changes which have occurred in sounding in comparison with item 2 to describe difficult enough. On the one hand this changes seem small, with another - strongly enough change a picture of perception of music. Such audiophile characteristics as localization, resolution, dynamics have certainly improved, but it seemed, what not this main thing in the occurred change of a sound.
The sound became, if so it is possible to be expressed, crystal, but not in sense firm and cold, and even more transparent, harmonious, "tasty". In general it is much easier to hear all it in real sounding, than to describe in the standard terms. The impression was made, that other sound-reproducing path slightly limits source possibilities. It is necessary to notice, that cMP2 became very critical to quality of supply mains voltage. I attribute it to the increased resolution and a transparency of a source of a sound. Replacement of a power cable on good firm one (Cardas Audio Golden Reference) cardinally improves all picture of sounding. In this case it is possible to speak about a power cable as very important part of an sound section. The source transparency is that, that allows to test easily quality of mains switches,preventers, filters, plugs, sockets etc.

Conclusion.
cMP2 (last update) beat the control source of a sound practically at all items. Some nuances of sound reproduction which are present at both sources and are undescribed in the given test, concern the category personal listener's preferences.

to be continued...
Serge.

I don't know why you're thanking me - I didn't do anything. Whatever, I'm glad you're pleased with it. (I assume your "dropouts" have vanished.)

The "minlogon" change will make quite a difference but be sure to make an imagefile of your system partition before implementing it. If you don't, it will definitely go wrong and you will then have to rebuild from scratch.

Just out of interest, what soundcard/DAC are you using?

I am a very polite German, so I was thanking you for telling me that it is worth to try the Intel Atom 230 board - and it is.

I use a PS Audio DL III tweaked by Dr. Moll.

 It would be great if, together with the "shopping list", you could provide us with a diagram/layout of the elctronics. Of course, if you are willing to make it public, like cics has for his project.

Thanks.

 did you make a comparison of pure linear psu with external clock vs CEC TL5100?
Which is better?

 4. Sounding сМР2 with completely linear psu, precision external clock and SSD 500 Gb SATA-II OCZ Colossus Series.
The changes in a sound:
- The resolution at silent levels of a sound has increased. It seems that a bass became less, but the resolution of a bass and its quality has sharply increased, it became accurately delineated, the stereo effect in a bass is easily distinguished. The nuances of mastery are more clearly shown.
- The advantages of SSD (in comparison with HDD) are shown more considerably on more difficult musical material though are appreciable on anyone.

Pin layout question; and any way of producing that PSU for others?, posted on April 10, 2010 at 07:36:48

 Seen the additional pics and your writeup on comparisons & improvements is useful.

I see P24's purple wire is ignored - only power lines (3, 5, 12 & -12) are connected. -5V is ignored. Actually based on your pin descriptions, you have implemented a P20 connector which should work. ATX 2.x P24 layout:



There's 100% match after renumbering pins 13-24 to 11-20 in above diagram: pins 1,2,11: +3.3 V; pins 4,6,8,19,20: +5 V; pin 10: +12 V; pin 12: -12V; pins 3,5,7,13,15,16,17: ground. Here's P20 layout:



How is it that you don't need a power up sequence? Pin 8?

I think one has to settle with an external PSU - perhaps its better. I would prefer the unit with 2 AC inlets (1 for P20 another for the rest including P4). Can one have this design produced in limited numbers?

 About pinout of connector P24 - I certainly was mistaken and have already corrected my previous message. Thanks, cics!
-5V is ignored - yes!
+5V Standby isn't ignored
"How is it that you don't need a power up sequence? Pin 8?" - I don't know, but it's OK! All voltages (pins 1,2,12,13: +3.3 V; pins 4,6,8,9,21,22,23: +5 V; pin 10,11: +12 V; pin 14:-12V; pins 3,5,7,15,17,18,19,24: ground) are supplied to the connector P24 SIMULTANEOUSLY by mains switch and THEN push the power button on the zalman's front panel.
"any way of producing that PSU for others?" - I am going to upload the documentation which will help to make such PSU.
"unit with 2 AC inlets (1 for P20 another for the rest including P4)" - Sorry, but I havn't understood that you meant: two ac inlets for two power cables ?

 Hi.

Cics, please, are there some kind of limits in the lenght of the files?. I have problems with long files (more than 90 min): the time of the tracks is not show correctly and cPlay jump back to the first track.

It's happens whit files with cue sheet. If I play directly the flac or wav file, it plays fine -but, obviusly, I have no control over the tracks-.

Thank you.
Ignacio.

 Hi Mihaylov!
Congratulation ,it is new achievement in development of cMP.
I build cMP with linear/battery PSU and thought about clock
improvement for Juli@, but it was difficult task for me.
It is greate news , that you with yours friend did it ,
showing a path for another.
Question:
1. Could you please show a picture or explain how you did it.
( I read on web , but not particularly about Juli@ )
2. About PSU- did you mesured noise level at P24 , 20mm from pin
or closely , using Oscilloscope?

Thanks, Gene.

Here photos. My friend used LClock XO3 24,5760 MHz (24,5760/512=0.048 MHz) because the mode output 96 KHz is used in cPlay.

 Thank you for sharing!

Have you tried disabling HT and using two physical cores instead? I think it *might* help with the crackling problem.

I'll be getting my i3 soon; can't wait to test it against the E7200+G45 combo!

 dear forum,

a bit curious about these SSD´s, and would like to know if it could be any advantage to run the cMP operating system on one of these ?
(-and keeping the music files on a conventional disk)

has anyone tried this ?

 Many thanks to Mihaylov for sharing the design of the linear PSU. Excellent write-up, but on page 6 there are a sentence in Russian I presume. Can you please translate?

Took quite a few attempts before successfully downloading the file.

 I second smicyta's request about Russian sentence on page 6 as it is about the fourth important psu for services like HD, monitor, usb...

Looking at the PDF I can only renew my congratulations and thanks.

 I am sorry. I hurried up and has forgotten to remove the Russian text from the final version of the document. The Russian text can be ignored, because it is translated in the following sentence.

 I want to add this to our cMP² site. Problem is its size at 24.8MB - compressing doesn't help. Only way would be to use smaller pics with lower res.

There will be 2 sections added under "Advanced":

1. Pure linear PSU (as per pdf)

2. Replacing Juli@'s XO

 It also has one less chip (therefore only 2 sata ports) BUT lacks BIOS flexibility.

Hi Mihaylov !
How do you think , can I use LClock XO3 45,158 Mhz and Juli@ will support it for 176.4 output, and if yes, will it improve shape of an impulse ? My oscilloscope show good impulse shape up to 96KHz .
Picture below 176.4KHz output. Thanks, Gene.

Hi Gene!
You should use LClock XO3 22,5792 MHz for the output frequencies multiple 44.1 KHz (44.1, 88.2, 176.4) and mount it on the Juli's board instead of the oscillator Х1.
I have not understood in what place you looked the oscillogram.
The oscillogram in output LClock XO3 looks so (I checked it).
If you are going to buy LClock XO3 pay attention to remarkable possibility of its usage (see the link).

It was taken from BNC Juli@ , this pictute show 41.1 KHz. As you can see, shape of an impulse in picture difrent. Any suggestion. Thanks, Gene.
