I'm a huge Mc fan, but agree with both Czarivey and Mitch2. The MC452 was not one of their better efforts, IMO. I gather you've tried your MC275 and probably found it soft in the bottom end with the 801s. You will need to get serious about going for higher current to bring out the best the 801s can offer.
When I was auditioning stuff a few years ago, I thought the MC302 blew the 452 clean away. The 302 was far more musical and neutral in comparison. I also found it superior to a similarly powered and priced Krell (don't recall the model now). After getting the 302 home and running it with my Rogers Studio 1s (very similar to the 801 in efficiency and balance) and C2300, I was very pleased with my choice and remain so.
The only change I've made since was to go with a C50 in place of the 2300. The tube warm-up time was just too long for me and I can't leave things on 24/7 because I'm rarely home.
Good luck & happy listening!
