As I recall: in some CD players (mostly very old ones?), there's only
a single DAC, which is shared between the two channels. The "left"
and "right" samples are converted back to analog at slightly different
times, in alternating sequence. The analog voltage coming out from
the DAC is then fed to a pair of sample-and-hold circuits, one per
channel, and these then feed the (low-pass) analog reconstruction filters.

As a result of this, there's a slight phase delay (equal to the actual
DAC conversion time, or half of the nominal sample rate for the stereo
signal) introduced between the two channels. This would tend to
"pull" the perceived stereo image slightly to one side, since our
ear/brain systems are sensitive to a signal's inter-aural arrival
times as well as to inter-aural amplitude differences.


** You need to apply some common sense before making such conclusions.

What does such a tiny delay amount to in distance ?

Answer:

your head being offset by 1.7mm from exact centre of a pair of speakers.


You are employing the worst of audiophool non-think which holds that IF it exists it MUST be audible.

********.
