oedipus,
no, you are stretching an inference too far and trying to put words into my mouth.
you asked whay a 5k cdp is better than a 100 dollar one. i answered with a list of things that could explain the difference either in isolation or combination.
can these differences can be measured? well that depends on the equipment used. if i use a sillyscope or a multimeter then possibly not. if i use my ears over a few weeks swapping between the two then probably yes.
my main problem is that electronicly measuring something that is meant to provide enjoyment is kind of missing the point of the excersise.
at the end of the day i'd be very surprised if you could measure 2 cdp's electronically and then tell me which one i'd prefer.
cheers
