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!!

As with all things involved with audio it may be simple or could be something further down the chain. I had a few amps from the mid to late 90's, Mc 300 and Mc 500 in that era were warmer sounding than current crop. If your 7205 is bright something is off. I used the 4 ohm tap with best results with any speaker/ amp combo, try that if not already on 4 ohm tap. Another cause could be when you switched out could the speaker wires became loose or became inverted at the neg/pos terminals?

..I was going to add maybe you're having a problem with your speakers/crossovers.

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.

If you plan to send it in you may also try audioclassics.com, they are all. McIntosh people over there and may have a quicker turn around. But you may try different cables and resolve your issue. But I would suggest calling both McIntosh and audioclassics and see what they tell you.
