What were the best years for McIntosh power amps...

Lots of McIntosh bashing here. I’ve had Pass labs, ARC, NAD, Counterpoint, Yamaha, Marantz, Pioneer, and others. Some of these were very good (Pass) and others not so good. ARC sounded good but was unreliable as hell. 
In terms of sound quality, reliability, and holding it’s value McIntosh bested them all. IMHO.

Your opinion, to me the sound quality went south, when they introduced output transformers for ss amp, which as you say made them, "at least" bomb proof.

One of the best Mac's ever made.

I agree with TLONG. You might check with Audio Classics, they do have the "narrow" version, which had a 16" wide face plate. The wider version, 17.5" is harder to find. I bought the narrow version and put the wider face on it. It's been a splendid amp for me. You also have nice speakers, and the 7200 will handle it with ease. Happy hunting!

I’ve got Aerial 7t’s with a new Mc 452 and it’s a great pairing. This idea that new Mac stuff is not good is bs!
