You might want to check out the PS Audio BHK 300 mono amps. They are surprisingly good, IME, and they can likely drive your speakers fine. They are AB, but with a higher A bias. I used to run a Reference Line Preeminence One amp that was 100W true class A, so I know the appeal (but, man, the heat!). These BHK amps are seriously musical and revealing at the same time, bring you to the emotion of the music.
They are hybrid amps, with 6922 input tubes and MOSFET outputs. My comments are based upon them driving TAD CR-1's, for point of reference.
