Being an owner of a pair of Apogee Centaur Major's, I'd say you cannot have enough power, whether it's from tubes or solid state. That being said, Apogees are unforgiving and any 'hardness' will be audible. But that doesn't mean SS amps aren't any good. There are many good designs that will work happily with the Slant's. I'd recommend amps like the older Threshold or current designs by Nelson Pass. Also the old(er) Krell class A amps will do the job, as there are many others. Just try to audition them in your own system with your own ears. I've tried a Bryston 4B SST in my system and didn't like it, but that doesn't mean you can't be perfectly happy with the B100 ST.
