That's possible. Capacitors can be pretty non-linear. But either you're
awfully sensitive or you have a good imagination. Trouble is that you
can't eliminate them without changing a lot of other things, so you
can't compare with and without.

That's one I have been able to do, at least to my satisfaction. On the
few bits of gear I have bothered to modify to add direct DC outputs, I
can switch the blocking capacitors back into the connection after the
new output stage. Flip the switch and hear the sound space blur...


I can't "see" anything testing with pure tones, but then what I hear
is mainly changes in the "space" of the soundfield, rather than in the
tonality of the music, so the differences are probably tiny phase
shifts.

You can see and measure phase shift with test equipment. You just
aren't trying hard enough.

Got me. "Someday" I hope to have access to good enough test equipment
and sufficient time simultaneously...
