You say that the digital read from your transport is better than the multiple reads of CD-Rom with EAC software? Thats interesting!!!

Well, tell me dive you data and you make your own concussions.  I read CDs with CEC TL0 with is not just a CD transport but it something really self-defined (if it is not broken) and this transport way more capable than any other transport that I have seen. Properly operating TL0  (with a proper fat DAC, as TL0 is “lean”) dose something as much as could be pushed out of “red book”.

Now the CD-Rom. There are very controversial rumors about the quietly of CD-Roms and CD copies. I have countless examples, with all imaginable technologies and none of them I find satisfying (except POD CD-Roms 10 years ago). Result is varying and quite unpredictably. A few years ago I decided to build high fidelity duplication with objective to get identical copy. I had a dedicated machine and I went to local Micro Center and bought I beeline it was 22 (!) external CD-Roms, DVD-Roms, Writers and etc… (I told them that I will return all of them except one and they were OK with it). Then I attached 4 of those external CD-Roms to my PC and loaded them with the blank CD that I use (MF’s UltraDisk). The EAC software has an option when it tries to read and to record CD and it builds up the list of preferred hardware for the given CD. I marked the CD-Rom that EAC recognized as the best and moved to another batch of 4 CD-Roms. Doing it again and again, and then running the test with the winners I was able to find one CR-ROMs that EAC recognized as the absolutely the best CD-ROM for the given PC, given disk, given PS, given EAC settings and …  whatever else. I returned the rest of the CD-Roms to the store and keep using the “best accepted”. The recordings that I’m getting on it are very much better then the recordings I was able to make by any other means but still they are not as good as I would like to.  So, another day I asked myself the very same question – will that CD-Rom read CD better then TL0. I read CD via EAC to file and played it. TL0 clearly was way more superior. Then I played the CD-Rom directly to DAC, many DACs,  with different cables, interfaces and so on… nothing was able to defeat TL0… Actually the difference is not minor…. If you find yourself in Boston I will be happy to demonstrate it.

It means that it is better to read once in a 'good' way than ten times to read garbage and average it.
So, all those hi-end CD players that use CD-ROM (or DVD-rom) as a transport just extract the same garbage multiple times.
I guess the reason is that a noise that come from CD and particular CD-ROM is not random. If it mistakenly reads 0 as 1 it may continue to do so due to its physical characteristics.  Otherwise, multiple reads should work at least as good as your CEC transport.
Such things do not happen to CD-data due to a significant space allocated for error-correction. Sure, who needs error correction for CD-audio, it only creates a market for expensive cd-transports.

I relay can’t rational on the subject. I have no idea why digital works when it works and I hardly have seen anyone who has. Of souse there are many people who know digital but all of them contradict each other and they have little understanding of relation between digital knots and bolt and Sound. At least I completely blind in the rationalization of digital reasons…

Somehow I don't beleive that a high quality DAC can be implemented in computer enviroment.

Perhaps you are correct, I do not know…

I don't think you are privileged to call yourself a 'psycho', since you are a rational person and have very well defined goals and thats the oposite from the 'psycho'. 'Abstract Audio' - you mean an Audio you can't hear? What you do is very practical audio (and I've heard your Audio result), and those on AA forum - they do Abstract Audio (afterall these are the same acronyms AA).

I disagree but this would be a subject for a different thread…

Anyway, I'll try to use my Creative digital out, if it gives fair results, then I'll upgrade to Lynx. Now I'm going to shop for a good DAC ..

Hm, I do not know Max… I have always difficulties to make purchasing decisions and I usually avoid doing them. I relay do not feel comfortable when I open my month and people buying things. I had many events in past when I advised something, people then run to buy and I always felt stupid.  I think people should navigate own purchasing decisions based upon very different motivation then juts somebody advise anything… Own objectives and own dissatisfactions with VERY SPECIFIC SONIC RESULTS that currently accomplished are way more objective purchasing navigation criteria then somebody else’s advisement…
BTW, regarding the Lynx. Being myself religiously Microsoft guy who within my professional trade not only despise non-Microsoft tools but also has strong detest to all that Unix/Mac/Lynx people I do acknowledge that I have numerous quite credible reports that Mac and Lynx workstations are better for sound. I personally never was able to confirm it as I do not even touch any box that does not run Windows…
