mcintosh MC 7270 or mc 7200


I am narrowing things down to several mac amps. I have a C39 pre, klipschorns. I am currently running tubes but have always loved the mcintosh gear. I had a MX132 and did like that but tubes took over. Now, I am staring a second system and have some mad money to play with. Once again, just looking for thoughts and opinions.

The big difference in the two amps, other than 70 more wpc in the 7270 and it has autoformers, is the 7200 is direct-coupled with no autoformers. Having owned both type amps, I like the 7200, and that is what I currently own. The bass is more solid in my opinion, and is a great amp!
My set up is a little similar - C35 pre, SET 300B 8W/channel amp, and speakers some what similar to Klipsh cornwall. Before I switched to tubes I had MC 7100.
After I tried tubes I would not switch back.
I just wonder - 200 watts into klipschorns? How big is your room? This should be good for the stadium.
