mc452 vs 601 vs. pair mc275 for classical music

What are you folks thinking about the new amps, 452 is now the 462, and 601 is now the 611.

I had one MC352 then two MC352's, then switched to two MC601 monos which I preferred. I then tried one MC275 v6 and then added a second MC275 v6 run in mono to compare. I liked them all but with a direct comparison with a C2300 preamp my favorite was the MC601 monos. I still have the MC 601's and have sold the other amps. I also have switched to a C1100 preamp which has also added to my musical enjoyment. If I hadn't done a direct comparison I would have been happy any of the combinations. 

I owned a MC275 MKV for a few years.  Great, gutsy classic amp with all around good performance, that sounded better than any solid state amp I've owned.   I have a strong affinity for tube amps, so solid state would not even be a consideration for me.

My system might give you a few ideas. The Mac electronics I've got are similar to the ones you are looking at.  Glad to answer specific questions if you have any.

I am very pleased with the Vandersteen 5A speakers in this system.
