Did you consider Spectron Musician III amplifier? Its both and warm and authoritative and in different class then both Bel Canto and NuForce, IMO, of course.
They have now promotion here at Audiogon and you can get one for $3.5k or with optional VCap caps for $4k - which is excellent deal for this amp
