'My CD-player (digital out to Benchmark DAC1) still wins over cmp on sound quality.'
I am shocked @ this. Are you using digital out to the benchmark or analog out from juli@?
Follow Ups:
both connected to modded Benchmark DAC1 by SPDIF:
** CMP - Juli@ optical out (removerd analogue part of the card) - vdHull optical cable - BM dac1
** Marantz CD63 coaxial out - coaxial 75Ohm cable - BM dac1
OS is very small nLite-XPproSP2-install, awe, mem=256-tweak. No steppe's or BitchBatches yet.
The old (but famous) Marantz wins. Not easily, but it wins. It's designed very neat, has separated power lines for analogue and digital and cd-mechanic, but not a very good clock (like juli@).
I was shocked too. I got rid of the Marantz a few years ago, because cmp won at that time. Two years ago i changed amp (Arcam A90 to Hexateq UcD400 with greeaat PSU). I forgot, until Junaid lately asked me to compare cmp and cdp. I'm unpacking my cd's now.
I still have to try Junaids batches and XP-Home.
Besides that i'm thinking of trying Voyage MPD as OS, but I'm not really at home @ linux.
I think cdp's only task is buffering data and clocking it right before passing to spdif-chip.
cmp-boards have a lot more functions and chips to feed.
That's why i'm thinking about Alix 1D + Juli@.
How about your cdplayers?
Has anyone tried Voyage MPD as OS?

I have tried optimising cMp to its utmost, but still the CD player excels in Musicality & overall enjoyment. The cMp sure sounds extended in the Mids/Highs but sounds Analytical when compared to a CD player. It was a big disappointment when i connected my Cd player after a real long time of working on the cMp. Inspite of tweaking & improving the cMp, both hardware & software-wise, it still does not stand upto a Mediocre Cd player as a transport. I own an ElectroCompaniet EMC-1 cd player, as well as an Arcam Alpha 9, & a Denon dvd-2930. Let alone the first two players (they sound far far superior), even when hooked up to the Dvd player as a transport, it beats the cMp easily. There sure may be more detail & air when optimising the cMp, but the overall enjoyment is somehow defeated. The bass & Mids sound way FULL in a cd player, as compared to the cMp.
Since i have spent so much time & work in improving the cMp machine, i felt its not fair to give up on it immediately. Instead i opt to try optimising it further for a while more, & inspite of that, if it still has a downside, i guess its wise to change over to traditional cd playback....
Just My opinion..
Junaid
I owned maggies for a long time, I believe you do too. I remember when I bi-amped or otherwise tried stuff that tightened the bass I got the same reaction as apparently you are getting now.
As in..??
Junaid
Thinner bass. A lack of fullness.
hi D,
Interesting result!
Are you using the recommended mobo or some other one? Which processor, etc.
Did you have both the cdp and cmp2 box running and connected during this test? If so can you just do one at a time disconnecting the other?
And why toslink vs. coaxial? Why not coax vs. coax?
2 things really. it is not clear this is actually a cmp2 box you are comparing, and even then I think you can only conclude that coax sounds better than toslink given what you posted.
Also were you upsampling or not?
No one here remembers the bending of our minds
Mobo is Atom-based Asroch AD525PV3. I tried this, because GA-H55M-USB3 was not satisfying SQ-wise.
See my post The Singing Atom:
http://www.audioasylum.com/forums/pcaudio/messages/10/100814.html
Coax/optical
- when testing, only one item is connected (cdp or cmp2)
- on both cdp and cmp2 optical sounds better
- i connect cdp via coax for convenience: optical cable is very tight, not easy to disconnetc; coax (BNC) easy to disconnect.
OS/box
The cmp2 is a cmp2 machine (cmp + cplay).
OS is small nLite-install as per Junaid/Rick. Networking possible (but in bios disabled, yet). AWE, mem=256, minlogon. Slimming beyond nLite not yet done. Later i'll try this and report.
Maybe if i try this, and the other reg-slimming and mermaids, the cmp2 will win (i hope so). Next weeks i'll be too busy with other things (work). If i can find the time i also want to try Alix 1D, i think we must try to slim OS ánd hardware.
A cd-player has very little hardware... and a tiny OS...
Upsampling
The Benchmark DAC1 upsamples to 176.4 KHz. The sound is best when CMP2 upsamples to 88.2 and then the dac upsamples to 176.4
