Hi Guys,
After almost 6 years of AOB and cmp(2) i decided to take another route and would like to thank you all for all i've learned.
Like Walter i changed from PCI to usb-i2s. I could not follow the last series of tweaks. I had great results with Jolida's iso and bitchbatch (@Jolida: i didn't respond because i used Juli@), but didn't manage to create time for further tweaks and experments.
This summer i changed to a usb-i2s/spdif interface, and PuppyLinuxMPD (mpdPup) as OS. I experimented with Alix, but chose an Asrock Atom board. Nice thing about mpdPup is that it loads via usb and than functions in memory. When it is started up, i pull the usb-stick. No HDD/SSD/whatever (well yes, there is one: in the NAS). Great sound, similar to Jolida's iso and Bitchbatch, BUT: streaming from NAS (very convenient) AND: i can play -yes- mp3 files!
A Raspberry Pi is waiting for further experiment this winter, when i planned to learn more about linux.Again: very very much thanks to you all!!
@ Greg in mississippi: since i do not use my Juli@ anymore: PM me your address and i will send it by mail.

Hi Douwe,
Right now I’m considering the same but for me it doesn’t feel as ‘Changing direction’. More like ‘moving on’.
Thankx too Cics cMP + cPlay project and the improvements suggested by other inmates I learned a lot. But I don’t like too severely cripple my XP installation close too dis-functionality.
So I’m now also looking at (puppy) linux distro’s geared towards audio. Unfortunately this only means: fully packed with software that is somehow related too recording and playback. So quantity over quality.
Untill now all these (puppy) Linux audio distro’s sound less too my ears than a fully ‘Steppe slimmed’ cMP+cPlay machine. But I still haven’t tried HQplayer from Signalyst on Linux yet
May be these linux audio distro’s can also be further optimized too equal of even pass the sound quality of a crippled cMP+cPlay machine.
Unfortunately untill now I still haven’t found a linux-audio forum on which inmates strive for real audiophile quality.
Do you know such forums or inmates on the net?

Hi Mark,
Have you tried MPDPUP? Pretty well slimmed down, plus low latency core. I have posted some settings that to my ear take it to a good place.
If you have tried comparing linux .. specifically MPDPUP or if you have never tried it..
Take it for a test drive. The author just put up a new release 9.3. OMG!!
Really nice pop in quality. On my system a level never before contemplated.
My Alix/WaveIO/TDA1541A rig loves this new release. I am ready to take on vinyl challengers. Bring it on!
Hi Walter,
yes I'm almost ready getting there.
For half a year I already have a GA-D525TUD Atom mobo lying arround.
I used it too test if the hardware and chipset had better SQ than the standard socket 1155 cMP Gigabyte MoBo's.
I could not detect any differences. So I continued using the 1155 socket mobo with with Celeron processor.
Seeing you, Douwe and others moving on this summer, made me curious how this GA-D525TUD Atom mobo would sound on Puppy-Linux.
But I don’t want too highjack Cics cMP thread. So I’ll start a new thread ‘How too get best SQ from Puppy Linux’.
http://www.audioasylum.com/cgi/vt.mpl?f=pcaudio&m=114482
So I continue in that thread.

Sorry to se you move on (not for you but for me). Pls come back and let us know how you're doing from time to time. Good luck.
Hi Theo,
I’m not planning too leave the audioasylum. I just need a new challenge. There is no progression in the cMP thread any more. I expect not many new software tweaks. I also don’t t like too cripple XP untill it almost breaks down too get good SQ from it.
Reading Wlowes and Douwe10NL moving on too Puppy linux inspired me too do the same.
I now notthing about Linux. It’s al new too me. But may be I learn just as I learned from Cics cMP project.
I notice a gap between the Puppy Linux’s newbie forum and the audioasylum PCaudio forum. The newbie threads on the Puppy Linux are still way too complicated for me. I don’t understand what is writen.
May on the audioasylum I can start a thread too brigde that knowlegde gap. Kind of: ‘How to get best sound quality from Puppy Linux for dumm’s’.
I already got an enthousiastic reply from Wlowes. But (again), like on the Puppy Forum - it’s much too complicated / cryptic for me too understand it.
I plan too periodicly report what I’m doing and what my progress is. I hope other inmates will respond or follow into experiments with Puppy Linux. This way there is chance we will all learn how too setup a Puppy Linux Distro and get very good Sound Quality from it.
WLowes, Douwe10NL, and I believe also Ryelands, already toke the plunch this summer. I follow now. May more inmates like too follow if there a thread on the audioasylum.

hfavandepas,
Have you explored mpdpup? It is designed to get you up and running without really learning linux. You will need to go through a relatively frustrating learning curve if you want to modify the various config files. mpdpup is a good way to get started without making changes and then read everything you can about beginners guides.
http://208.109.22.214/puppy/viewtopic.php?t=70052&sid=3d93dcb742a75f80aa0c8624ad187360
I did find a good manual describing the basic concepts of file system which i'd be happy to email.
My own experience with MpdPup is one of mind numbing frustration. I think that you probably need a very special mindset to figure it out. It’s supposed to be the simple route to linux-based audio, but I certainly couldn’t get to grips with it.
I’ve kind of given up on Linux as a possible direction because most of the stuff I’ve looked at is just way too flaky and seemingly dependant on the user being able to master a whole new language in order to comprehend the cryptic screen messages.
Cmp/Cplay still seems like a nice approach to me. What I think it needs is further development in areas like the user interface.
Douwe,Thanks for the bounty of a Juli@! I've responded separately. I'll hold it in reserve for someone who needs one (perhaps after a botched mod!).
Please don't be a stranger and keep us updated with what you're doing, especially your innovative HW mods.
I personally am also interested in what you're doing from a player perspective with PuppyLinuxMPD... and also your experience with an Alix board. I've been interested in trying some different player setups and have been looking at an Alix 1D (with PCI so I can use a powered-Juli@) to try as a headless NOS cMP player as well as a server for the Squeezebox Touch I recently bought and also as a PuppyLinuxMPD player. Maybe post your experiences in the 'Tuning Linux/MPD/Alsa for best sound on ALIX processor' thread? Or if you already put them somewhere else, point us to them.

P.S. I forgot to mention that with the latest slimming tweaks, the slimmed version that works with Juli@ is STUNNING!
Everything matters!

Hi Greg
If you play with Alix, I'll point you to a couple of key tweaks that bring out the best. One inmate suggests the 1d over the 3d2 I use as it has bias control you would enjoy. I had good success with replacing a couple of caps and of course had to add some blackgates. Sounds like you have CMP really perfected. Interested in your comparison. Of course, stay clear of Alix if you want to upsample in real time. Now way it has power for SOX or SRC. It is strictly NOS.. fine by me as that is my preference but each ear is different. You should consider WaveIO with the Alix. You could reserect your 1541 dac + WaveIO as an alternate to current rig?
