System very bright after adding Mcintosh amp

So, I recently added a Mcintosh MC7205 amp I purchased off of audiogon to my system. Im using a Marantz Sr8002 as the pre/pro and have b&w speakers (683 fronts, htm61 center, and 686 rears)

Anyway, I've noticed that recently the whole system is abrasively bright. It sounds like whatever I am playing is a poor-quality mp3 and hits those high-end pitches that almost seem to pierce your ears.

I've re-run audessy since adding the amp but didn't notice and improvement.

Any thoughts or suggestions?

Thanks!!

Well tried playing with a few more settings and the Level controls on the back of the amp and still not much luck.

I can try different interconnects, but thinking I may just call MAC on Monday.

Unsound-- that's a good thought as the b&ws do have varried impedance, but unless I'm mistaken, I don't believe the mc7205 has the auto transformers. I don't think MAC introduced those until the mc205/207
