As stated, I only tried it on a PS cap, there is no "coupling" caps in a direct coupled SE amplifier, unless a cathode by-pass qualifies.
And yes, I see that caps have different speeds or bandwidth preferences, but this is NOT good! It means only very very high quality (if that exists) can "replace" the need to compensate with somehow "chosen" multiple small value paralleled caps. I hate it! But, I accept the challenge of at least trying to compensate for true losses. It is seemingly a necessary voodoo.

Can anyone recommend a cap that when paralleled with quality small caps,
doesn't sound ANY different? for example a 50uf/600VDC ? This to me would indicate that the speed/bandwidth performance of the main cap was "good enough" to not be enhanced by whatever "superior, less lossy" effects the additional caps could provide, along with whatever "smear" they are also adding?

Yes, I use 0.22uf to 10uf caps for PS bypass, not 0.001uf - Chris O 19:52:51 06/27/12 (1)
