What a great thread! I had experience with a few of these. I tried the Classe', owned the McIntosh 275 Tube amp, but tried a pair of 275's, and finally landed on the McIntosh MC402.
The 402 provided deeper, more detailed bass performance and in my system sounded better. I did not hear the Musical Fidelity so no comment there. I also had an Audio research solid state unit a while back. I still like the mcIntosh the best in my system.
