I tried a 4bsst with my 3.6r's and the sound in my room was a bit bright and lacking in bass.Not enough power. Along came my Classe CA-400 that puts out 800w at 4 ohms and all is well.Used prices for these are in the low 2K range.
The Classe CAM350 as you listed would be an excellent match for a smooth sound.
Agree with Bob reynolds and Ackman00. You should audition the Parasound JC 1's. They great sounding amp's. Check out Stereophile January 2010 issue. M. Fremer compare them to Bryston 7Bsst'2, he likes the Parasound JC 1 better. According to John Atkinson's measurement test. The Bryston's has low input impedance that may be problem matching with preamp specialy tube pre and in his measurement into 2-ohms load the Bryston 7Bsst'2 didn't do as well as the other amp's tested.
I had the Parasounds in my system a few years back, I really loved those too. Excellent choice. I don't know that I liked them better than the Bryston's, because they were a couple iterations of amps apart, but I did really like both of them.
I listened Mag 3.6R with Ayre MX-R, which was nice... but a bit too expensive.
Yesterday, I learned that Magnepan and Bryston will exhibit at T.H.E. show in Las Vegas (Yes, in same room, I think that means they'll pair up each other...)
Think it will a good chance to compare Mag with 4B and 14B. (And perhaps chance to listen to many other sound systems)
I'll try to give ya'll a full report after I come back :O)
