Reference Transports: An overall perspective


Teajay did a great job by starting a threat called "Reference DACS: An overall perspective."
I thought it might be beneficial to start a similar thread on transports.
Unfortunately I really have nothing much to say; I just hoped to get the ball rolling.

I'll start by throwing out a few names and a question:

Zanden 2000
CEC TL-0X
Metronome Kalista; T2-i Signature; and T2-A
Esoteric P-01; and P-03(?)
EMM Labs CDSD
47Labs PiTracer
Weiss Jason
Accustic Arts Drive 1
Ensemble Dirondo
Wadia 270se

I know that there are very few companies that actually make the drives themselves. The few I know about are:
Philips
TEAC
Sanyo/CEC

Do the various Philips drives or the TEAC VRDS transport mechanism each have a particular sonic signature regardless of which maunufacturer uses them in their designs?
exlibris

We may have gotten a bit side tracked from my original response. Here is a very simple example of why a transport makes no difference. We build the following hypothetical system. This system consist of 3 boxes interconnected. They are:

A. Transport only
B. RAM only
C. Digital filters/DAC/Output stage

These 3 boxes make up a complete CD player. The following lists a step by step process to listen to music.

1. Download entire song from Transport into RAM, error free of course.
2. Turn OFF Transport and disconnect it from RAM.
3. Discard Transport into an incinerator and burn it.
4. Play music from RAM thru box C which has the digital filters and DAC.
I finally came back to this post after starting it way back in March. I'm sure no one is still following it but if they are, here is my take (to quote Lktanx with an important modification):

"Here is a very simple example of why a transport makes [A] difference."
In real life any fool with a pair of ears can hear that some with error free output sound like crap and some with error free output sound like music.

Yes, pragmatism, empiricism, and experimentation are all that I have to offer.

One can continue to argue that transports SHOULDN'T make a difference but to argue that they don't make a difference is simply un-scientific:
1. You've hypothesized that transports shouldn't make a difference to the way CDs sound;
2. You run a controlled experiment where you test your hypothesis;
3. The experiment shows that there is an enormous difference in the way two transports sound (even though both provide 'error free' output to the DAC).
4. You must scrap your hypothesis and move on.
"Here is a very simple example of why a transport makes [A] difference."
In real life any fool with a pair of ears can hear that some with error free output sound like crap and some with error free output sound like music.

Exlibris, Your take, using a pair of ears, can also find some support from a pair of eyes (actually, one eye is sufficient). Check out the following link for a pictoral comparison between Esoteric's VRDS-NEO transport and some other transports, including some that are used in top-tier players. For me, it's an example of a picture is worth a million words: http://www.aplhifi.com/phpBB/viewtopic.php?t=560

Thanks for your thread, it's been very informative.
