Your amp should have more than enough power. You should really try to borrow gear and swap only 1 piece at a time until you find the culpret. If everything is sounding harsh when played loudly, you can eliminate the cd & cable (compressed music usually sounds flat, not bright).
Borrow a stereo only amp if you need to just to run the right and left channels to compare to the adcom.
Personally, it doesn't seem to me like your system is balanced. You have shorted yourself with not enough spent on the sources, nor on the cabling. What speaker cables are you using, do you have a line conditioner?
