You should re-read the trouble shooting he's done. Your brand loyalty and generalizations are more than idiotic. He already stated that with delay the amps don't make the noise. ie, it isn't the amps. Could be a combination of things, but on their own the amps don't do it.
I realize it is hard for you to swallow that you spent a bunch of money on stuff and could have had a way better sounding system spending way less, but stop making odd projections based on zero facts and only emotion. Decisions and discussions on emotions don't fare well on forums.
