Bryston or McIntosh which would you buy?


I currently have a McIntosh MC752 amp, and am considering an upgrade in the future. I know the 752 is not one of McIntosh's best amps. I love mac gear as I always wanted to own their equipment.

1) How much of an improvement will I see going from the 752 to say a 7270 or similar?

2) How would it compare to something like a Bryston 4B?

Please note that there is a good chance I will upgrade my speakers...looking strongly at Thiel. Current preamp tube based Aronov.

Thanks.

Why not use both and bi-amp your speakers if they can accommodate them. That is what I have. The MC275 on the middle and top of my VR4JR speakers and the Bryston 4BST for the bass units with a McIntosh C2200 as preamp it is easy to set up. They match perfectly.
I would upgrade within the Mac line (Autoformer coupled) because I prefer the sound to Bryston, which is also good. In your case, I would stay with Mac especially since you are using Thiel speakers, which can tend to be bright, which Mac isn't and Bryston can be.
There has been quite a few Thiel,Bryston demoes at audio shows
Even James Tanner(Bryston) uses Thiel speakers(among others)
with 2XSS-2Thiel subs.I'd audition them at home if you can.
It does seem like Bryston and Thiel mate together very good.
