I didn't see too much BS there.. It looks like he working a bit too hard to
analyze and explain a relitivly simple situation (like his 99th generation
test to prove that jitter is not culmitive, DUH).

Without reguard to his understanding of technoligy, this person does
understand music. Listening tests show that sub sample jitter is audible. It
is measuable and it is correctible (with a good buffered and seperatly
clocked DA).

With a perceptual compressed format, jitter is probably not the first of
your worries. :) However, playing off your HDD could very well have sonic
effects in a typical computer: The DACs in most soundcards are almost
unisolated from the system that powers them, voltage changes in the system
DO come out audibly on such configurations.
