I have a 4B3, and I think it's a lovely amp. Presumably the 3B3 is similar.
Just as the 3B3 is the little brother of the highly rated 4B3, the Audio by Van Alstine Fet Valve 400R is the little brother of the 600R, which has gotten great reviews. It's priced at $2900 (with the more attractive silver panel and integral DC blocker to kill any transformer hum). The AVA gear offers outstanding value for the money.
