You should add the Bryston 7B-ST monoblocks to your short list. They are of reasonable size, offer a combination of excellent power and sound quality (rated "Class A" by Stereophile mag), and have a 20-year transferrable warranty backed by probably the best service in the high-end industry. A new pair sells for $5000, and can often be bought used for around $3000-3500.
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.
