Probably so.
Before even considereing DA, hi-K and also medium-K ceramic caps produce
measurable distortion and so shouldn't be used for signal coupling or feedback
networks.

Most pro-audio equipment uses large value coupling electrolytics in

Ever wondered why ?

Large value coupling electrolytics where? In what type of audio equipment?
Output stages? If there's no dc bias then they'd have to be nonpolars, no?
I have read that larger-value coupling caps result in increased bass
response... why is that? How are output coupling caps sized, I am guessing
lowest-cost for "acceptable" performance. Can any coupling cap be replaced
with one of a higher value?

Shhhhhh
Next thing you know, they'll be complaining that the EFM encoding
introduces noise unless read by a gold tabbed laser - only that would
be good enough for audiophools.
Not sure about "gold tabbed" but certainly if your laser isn't
'silvered' with sputtered gold, your listening pleasure will be marred
by quantisation noise, as any audiophallic will tell you.

It's easy to overcome this with careful use of the "belt pen" and "quantum
clip."

Don't forget to buy some quantum rainbow foil.

| Ok you audio nuts most of the noise that you hear come from the firsyt stage and it is and forever will be white noise. Any other noise is caused by faulty components maily resistors. capacitors in essence supposed to be a dead short to ac so how can they generate anything if healthy. This a ploy to get some nut to spend money. In digital circuit yes there are some caps better of filtering because of cap property but for audio give a break |
