Today's Transport War: Significant Differences?

I have been reading much these days about computer/hard-drive based transports as being a whole order of magnitude superior to traditional CD transports. In my reading, the camp who believes hard-drive based transports can render major improvements has been most notably represented by Empirical Audio. The camp which suggests that traditional CD transport techonology (or atleast the best of its sort--VRDS-NEO) is still superior has been most notably represented by APL Hi-Fi.

Each of the camps mentioned above are genuine experts who have probably forgotten more about digital than many of us will ever understand. But my reading of each of their websites and comments they have made on various discussion threads (Audiogon, Audio Circle, and their own websites) suggests that they GENUINELY disagree about whether hard-drive based transportation of a digital signal really represents a categorical improvement in digital transport technology. And I am certain others on this site know a lot about this too.

I am NOT trying to set up a forum for a negative argument or an artificial either/or poll here. I want to understand the significant differences in the positions and better understand some of the technical reasons why there is such a significant difference of opinion on this. I am sincerely wondering what the crux of this difference is...the heart of the matter if you will.

I know experts in many fields and disciplines disagree with one another, and, I am not looking for resolution (well not philosophical resolution anyway) of these issues. I just want to better understand the arguments of whether hard-drive based digital transportation is a significant technical improvement over traditional CD transportation.

Pardales; I hear you man, I was there and I have a bunch of *.wav files on my hard disc, then I noticed I stopped listening to whole CDs, I would just skip through songs, then I took longer looking for that song than listening to it (probably my inexperience), then I realized most of my favorite songs are not the HIT sinlge of the CD, but something I found by not standing up to change the CD, My Favorite movement from Bethoveen´s 9th is the Second while the Coral is the the Hit! (just an awful example, a symphony should be listened from begining to end).

Another thing; for critical listening I just could not bear knowing it could sound better hooking up the machine behind this one...but thats just me!
I am glad it is working out good for you though!
Maybe I will get a Hag-usb and try again!

How many favorite songs did you discover that are not the ones you bought the CD for?

What about vinyl?

Jsadurni - too bad about your experience with the SB. I have found that USB audio is much better quality than Wi-Fi (even though I sell an Off-Ramp Wi-Fi), but dont expect miracles if you buy a cheap converter. USB audio can outperform most transports IMO, but ONLY if:

1) you use a custom S/W driver - only comes with certain converters
2) you avoid the TI 270X chips - most of the converters are based on this
3) the converter is clock by a low-jitter clock, such as Superclock
4) you use a PC and SRC upsampler
5) you use the right ASIO plug-in

I know it's a lot to consider, but the results are well worth the effort.

Steve I am probably a future costumer of yours (after analog), I will need my current DAC to sound the same as it sounds with my current Transport..thats all!
I will use a little black box (Hag-usb, offramp, Lynx card, etc.) with a digital output, the input can be USB, Ethernet, Wifi; whatever sounds good!!!

I am soo happy with my cheap DAC, I am thinking twice about vinyl!!!

Jsadurni/others: I reached a personal conclusion on this over two years ago.
Fingertip access to my 9000 songs through iTunes is IT for me.....NO going
back. Having all my music on iTunes lead me to listen to more of my
collection
than ever before. I have not had a conventional CD player in over a year. To
me,
ACCESS IS EVERYTHING and having almost 900 albums on iTunes gives me
at-a-
glance access that I cannot duplicate with the physical media (CD's) no matter
how I organize it (racks, shelves, binders, etc.).

That said, I initiated this thread to try and better understand some of the
technical aspects of the current deabte going on about computer playback of
music versus conventional CD transportation. I have learned much from this
thread and appreciate the input of everyone who has participated.

The conclusion I have reached from this thread, and my other reading on the
subject, is that a thoughtfully implemented computer transport can compete
with all but maybe the most tweaked hi-end conventional transports.

Before jumping to conclusions about the Nova Physiscs Memeory Player go to their website www.thememoryplayer.com and read why their approach to get at the data on the CD is completely novel and does NOT resemble buffering, reclocking, oversampling, etc. Also remember that the Nova MP can only play back what has been recorded. It cannot reverse or correct any problems in the recording process and/or manufacturing stage. There is no DAC on this earth that can correct errors due to insufficient transport capability.
There are also two reviews out there on Positive Feeddback Online www.positive-feedback.com and The Stereo Times www.stereotimes.com
