-but in general if the power supply has timing constants that are higher than that of the amplifier circuit, there will be some instability in the amp (LF resonance) as a result.
These days we are more likely to fix that with bigger filter caps, but actually cutting off a little higher with a smaller coupling cap is the better move IMO as the cap will have less effect otherwise on the sound- its easier to build a good small cap than a good big cap.

And in addition, smaller coupling caps can produce a much shorter overload recovery time. I'm always careful not to use caps that are larger than necessary for this purpose.
