Should We All Hold Off on Buying CD Players? - Page 5

post #121 of 128
Yes, but I trust the ears in this forum much more than a Sellers claims. They have a very vested interest after all.

What does actual experience say?

That's the question. Lyngdorf claims it will, because a CD-solution allows the designer to provide an optimized and clean clock dedicated for CD. This quote is from the reference above:

The reason for designing for CD rather than DVD/SACD is obvious from a musical point of view. All DVD/SACD drives are based on video designs and clocks, and the output is re-sampled (uncontrolled) to audio output clocks. So our preference is simpler and better: a good audio drive, a clean clock on the drive and external optimisation. We have chosen to get the signal (off the CD) as cleanly as possible and do the last final cleaning based on our precision clock system close to the output stage.'

If you go over to AudioAsylum and search for posts by Charles Hansen you can read how he solved the clocking problem in Ayre's "universal" player (and other things). You can switch clocks, it's just tricky to do it right.

Just wondering here. Are they telling you how they solved the 'clocking problem' (not that they've defined it in any tangible way) because they struggled with it while others, let's say Oppo, didn't have to struggle?

Actual experience says that there is a difference, although you would think that "digital is digital" and that there should be no difference whatsoever.

IMHO the issues with clock and jitter is a plausable explanation to why there may be differences that in theory should not be there. (In theory a $10 DVD ROM should sound the same as a $2,000 CD player when digitally connected).

That depends upon how you do your 'actual experience', Peter. I think even more plausible explanations why there might be differences even when going digital out to some external DAC are as follows:

1) Insufficient amplitude or signal strength.
2) Issues with rise times.
3) Poor drive current capability meaning that it's ability to drive capacitive loads is compromised.

Maybe a DAC that intimately derives its clock from the incoming data stream. BTW, where can I buy a $10 DVD ROM?

Excellent point! That may explain why some people claim they can hear a difference between TosLink, S/PDIF and AES/EBU. In theory these should all sound exactly the same...

You already knew the answer: eBay

You know, if those are the really the reasons, then we're talking about junk players, regardless of price.

BTW Peter, have you seen the test reports of the Lyngdorf over at MillerAudioResearch (http://www.milleraudioresearch.com/d...gdorf_cd1.html)? Seems that it performs quite well, but interestingly the output is a little over 5 volts. I'd imagine under casual comparisons that in itself would lead to an ability to stand out in the crowd, no?
