Audio input caps. Which one?

That is because the cap at the bottom of the NFB loop is essentially a coupling cap so provided it is is big enough it has little AC voltage so can generate little distortion - and signal levels are low there anyway. Passive crossover networks are audio frequency filters run at significant AC voltage so cap properties show up, although they are still swamped by driver properties.

Indeed, and I am a believer in we are not drops in an ocean, rather a whole ocean in a drop. I do not want to ignore micro distortions that add up. Especially if it s cheap fix.

Use good polypropylene caps or mica for small values. I have good experiences with jb Capacitors - Just Your Best Choice series JFX and JSX. They are cheap and sound good, or better said do not "sound". In general I avoid coupling caps, dc coupling is preferred whenever it's possible.

This leaves us with polypropylene and Polyethylene types as good options.

Coming to reasonably priced good caps... WIMA seems to be the flavor of the day for most folks... but with a dizzying array of models... I wanted to know what you guys preferred.

MKS, FKP, FKP2 etc....

If Wima, than MKP10, FKP3. For coupling I prefer Kemet SMR.

Thanks guys
