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!!

Stupid jobs! Always get in the way of what really matters:) Oh that money thing.
What amp were you using prior to the 7205? I owned a 7205 and used mainly for center and surrounds at the end of my time with it. I was using a MC352 for the fronts, but prior to that the 7205 was driving all 5 channels and they were Infinity Kappa 7's, a bright speaker. I can't recall it being overly bright or poor quality. I will add that the MC352 had an entirely different sound. One I attribute to the power but also the autoformers.But if you are getting a bright sound of B&W speakers, I would question that particular amp. Do you have a McIntosh service center in your area that you can have it checked out?
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.
The MC7205 does not have autoformers and neither do the MC205/207. They have only made one amp with more than two channels that uses autoformers and that the 3 Channel MC303. 5 Autoformers for one wouldn't fit and the amp would require a forklift to move. Jastone you only have a 4 or 8 selection to choose from and a input variation selection for each channel on the 7205. But I seriously doubt these settings are creating the issue you seem to be experiencing. Were you able to contact Mc or Audioclassics today?
