A contrasting opinion here. IME with the Heresy I, solid state amps were just not that much fun. They are hyper-efficient and move a lot of air. I tried several solid state set-ups from Sansui, Akai, Tandberg, B&O, Carver, Crown and others. Was never satisfied; the sound was just harsh and fatiguing to my ears. Too efficient for them, I believe. Maybe just too much IMD? Could be - that was a concern back then.
Heard them several times at dealers and friends places with Dynaco, McIntosh, Conrad Johnson, Fisher and other tube gear. They just seemed to come alive. Class D wasn't around at the time, so can't speak to it. I did audition a Class D (not sure of the brand) with some Martin Logan Montis a while ago. Same sort of harsh sound. Brash is the buzzword that floats up from the past that seems to fit.
Compatibility is a different issue. The amps will drive the speakers, no problem: Fairly stable impedance across the frequency range. You do want to be careful how hard you push them though. Heresy was only designed for 100 watts or so and the T35 style tweeters have voice coils that are easily toasted with too much juice or distortion. As a general rule of thumb, your ears will cry "uncle" before you hit that point, but be aware.
Give the rig an audition and tell us your impressions. What we think isn't what you'll hear, and that's all that matters. Good luck & happy listening!
