Is my new amp TOO GOOD?


I recently took advantage of the McIntosh Upgrade program.  I traded my MA352 integrated hybrid for the C2800 tube preamp + MC462 ss power amp.  I have a large room with Revel Studio 2 speakers (with beryllium tweeters), and two SVS subs.  I also have some room treatments on the walls.   

I traded up because I wanted to see if I could more detail with the extra watts while keeping the tube sound I like.  

So now I have much more detail, but its sometimes too much.  Higher frequencies - like high pitched loud vocals, and some of the detail now sounds almost like static.  If I turn the volume way up I can hear that its another guitar or a background vocal.

I have turned the treble down from -1 to -4, and I can't listen at 90 db all the time.

Does anyone have any suggestions about adjusting the eq/

When buying HIFI gear at this level it should never need or have to go through a break in period to get it to go from bright, scrill, fussy, boomy or other type of BAD. It should and will go from Sounds Great to Sweeeet.

Check your cables, interconnects etc.  If all is good take the new gear back to the HIFI store a tell them you are very concerned something is wrong and need their help. I would hope they respond correctly. If not request your amp you traded in and a refund of your money. Don't be angry or rude as that would serve no good outcome. I hope all works out for you.   

You people telling him to get new cables are a joke. If you're too ignorant to offer good advice, then just don't post anything. 

As much as I have read mcintosh  tests everything that comes out assuming it's not b stock. Unlikely got damaged in shipping.
