Based on your comments that the musicians are finally in the room, from one of your other threads, I would say replace the Brystons with Brystons. The new cube series was just released so it's a great time to be upgrading them. The Mcintosh amps are fine products for sure but the brystons are also very fine amps. I have multiple customers that went from some of the top amps (pass labs, classe, etc) to Bryston due for their speed and realism. I am a dealer so take it for what it is though.
