Dennis Fraker explained this on this Forum, a few years ago, and has it PERFECTLY executed in his Serious Stereo 2A3 DC amps.
1) Never one cap, because the music will tune to that value.
2) Never a electrolytic.
3) Multiple value film caps rule !! Very often five or more in one Rk location.
4) Even though a cap can measure wide band, in cathode bypass duty, different value caps play the speaker in a NARROW band.
5) Put your main film cap value in place. Listen to that. Then, over time, you bypass that cap with lower value caps, determining the values, and the makes of film caps by ear. The process may take you up to a year of break in and listening time, to find the optimum values and types. If your system is mediocre, you may never find it.
6) If and when you optimize it, the results sound wonderful.
No free lunch, you have your work cut out for you, so, open up your wallet and pull out five C-Notes to start. You are in the audio big leagues now Neff, no more cheapo kiddie stuff.

One bypass cap value will do depth. Another cap value will do juiciness on the soprano's lips, and another cap value will do extreme air. Your job is to BY EAR, find the values and the best types.
