Electolytic caps come to mind here. However I would hope that a decent
design would be built to avoid this. Indeed, apart from power
reservoirs, my understanding is that electrolytics are generally
avoided these days in equipment with 'audiophile' aspirations.

Let's talk about the part of every stereo system that has strong effects
on sound quality but is totally out of the control of audiophiles - the
recording and production equipment. If you peruse the schematics of
typical audio production equipment, there are many electrolytics in the
signal path. Ironically, a production facility might use high end mic
preamps with lotsa film caps or servos or both, but you'll find plenty
of them in the mixing console, mastering facility, etc.

Indeed. This was why I referred to "...equipment with 'audiophile'
aspirations." ;-

FWIW One of the 'criticisms' that was aimed by a reviewer at the amps I
designed years ago was that I dared to use electrolytic caps in various
stages. I still seem to lack any sense of shame or embarassment about doing
this, and probably would do so again if the results sounded and measured
fine to me. :-) This is despite being aware of various 'problems' with
electrolytic, and various other types of cap.

Slainte,

Jim
