Any particular reason for exclusively looking for Class A solid state?
While there are alot of great Class A amps, I think you can get the same level of performance from a good Class A/B amp. I've had Class A amps before, and I'm just not comfortable with something generating that much heat in my room. You can fry an egg on some of them. More importantly, I've heard of them baking the circuit board over time and lifting the traces.
Of course, there are tons of people who've never had a problem, but why deal with the extra heat, power cost, and reliability issues if you don't have to. Nevertheless, if you want Class A suggestions, I would check out the Plinius. Also, I haven't heard it, but Bedini supposedly came out with a Class A amp that runs just warm to the touch.
