I've used a pair of Pass Aleph 3's (obtainable for around $1000 each, with patience) very successfully as monoblocks, paralleling both input and output, as per Nelson Pass's recommendation. My only knock on these amps is that they take an hour or so to reach their top performance. But their top is pretty high, if you like solid state at all, IMHO. I think you could do a lot worse.
Small balanced monoblocks
I have Meadowlark Heron i speakers, with a Wadia 830 front end, BAT 3i pre, and SS amps. I have a small, lively room the system is set up in, and am looking for suggestions for monoblock amps that would likely fit in. Any suggestions are appreciated, with $6000 tops new/used my ballpark for now.
