Trevor, jurb: R.E. "phase of the channels"
Is there something I don't know
about CD players, or how they
function? Does the audio arrive
out of phase/polarity at some
point in the chain inside the
player?
**It did with the CDP-101, because only one DAC was used and shared
between left and right channels. All (?) other players used two DACs
(one for each channel) and the delay was not required. For the record, I
just checked the schematic of the 701. The 701 used two DACs. One for
each channel. It does not use a delay on one OP amp. Both OP amp
feedback resistors are 15k, paralleled by a 75pF cap. This likely
contributes to the difference in sound quality noted by many listeners
(including me).
