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.

I've yet to see either camp come up with any meaningful data that would justify my $'s (i.e., if you can't measure it on the back side of a d/a converter then I doubt if you can hear it). Something I think audiophiles overlook is that digital data transmission is very forgiving by nature, as long as the bits get there at about the right time and at about the right magnitude, well designed equipment on the recieving end can reconstruct and reclock the 1's and 0's. You could watch a satelite hdtv and note the crystal clarity from the much higher speed digital data transfered back and forth through the atmosphere, and then decide if you want to worry about the bits from your transport crawling slowly to your dac across a couple feet of cable.
