If one is unaware of an unpleasant fact or situation one cannot be troubled by it.
Ignorance is bliss in this case.

I am guessing that most of the capacitors that you replace are part of the power supply or at least connected to a fairly constant DC source.

Voltage across caps does not change with volume. Not in power supplies (obviously), and not even the coupling caps if correctly dimensioned. This is delusional.

Maybe your missing something . Something is happening inside those big KZs and Silmics and can take up to 200 hours to fully break in . I don't know what but is real. I always use other references for AB tests . Is obvious that your not using a well treated room and other amp references or hi quality speakers in order to see if this break in is really real or not .

Getting used with a sound or your brains being able with some "training"(200 hours) to hear only what is really meaningful and ignore the "noise" is part of cognitive science, not audio engineering!
That thing also happens with painters when they get so used with some nuances that they need at least a few hours to look away , working with other colours to be able to tell apart the fine difference between nuances when they get to work with them again...
Lo-fi equipment never need breaking in because its bandwidth is already reduced so the noise is reduced too...
I have to tell that again: i understood a lot of the very wrong "audiophile ideas" after i have dealt with some high quality cassette players and their Dolby systems.Dolby was a genius in his noise vs music analyses. The sliding band noise reduction system works because is just enhancing what we already have implemented in our brains by millions of years of evolution.
A similar sliding band harmonic reduction takes place in valve amplifiers so that we mainly hear the harmonics of the lower frequency signals due to the output transformer saturation by the frequencies with the highest amplitude and that was a key aspect of simulating valve amplifiers with silicon transistors and is actually the main theme of one of the best valve emulator patent which understood why the output transformer is so essential in valve amplifiers.

You don't pay any attention to what I'm saying . I repeat I also have other 3 amplifier as reference. Total 4 amps. . So no I'm not get used by the sound because I always switch from one amp to the other 3. Sometimes I use an amp for 3 days and after that another amp for just one day and so on ..I always have 4 amps hooked to my soundcard.
When I first installed the caps in Yamaha A-700 the sound was really bad with poor highs and resolution compared to the other 3 amps.

do you have 4 identical amps modded with different capacitors?

This is long overdue, with a bit of luck this thread will now be closed along with some of his others. As a matter of interest, why are people engaging with the OP?

Robert, I think you are not who you pretend to be. Too many contradictions, you seem a reasonable intelligent person yet pretend to completely miss the points being made here. It's the same in a couple of other threads you're in.

I believe you really know quite well what's going on, but that you are trying to see how far you can get pulling our collective legs.
You wouldn't be the first. Nice try!

Jan
