I question Mr. Kruger's assertion that "good accurate digital reproduction

sound different in DBTs, why shouldn't CD players?

Except I am using the same DAC. The optical out from my DVD player went
and the optical out from my Apple TV goes to this device. Since I
really do believe bits are bits, it has to be the differences in the
transports, DVD/CD vs. HD.


That's possible, I guess, but I always have to wonder. AFAIK, most
transports use a FIFO for the data stream. So even if the transport is
jitter-prone, and the bits enter the FIFO in a somewhat helter-skelter
fashion, They certainly march out of the FIFO re-clocked to a level of
precision that is dictated by the accuracy of the system clock. Would that
not be so? I suspect that the capacity of most of these FIFOs is finite and
that one for a DVD drive would be larger than one for a simple CD player due
to the increased data density of DVD. Therefore, it stands to reason that a
CD played in a DVD drive might be less prone to overrun that drive's FIFO
than it would a FIFO in a CD player, but I don't know that for a fact. But if
so, it MIGHT explain why DVD drives make CD transports that are less jitter
and error prone, but I don't know enough about that end of the playback
process to say one way or another.
