Well,
I am also looking at tube amps and this was an email exchange with a buddy. I am looking for an amp to drive a new pair of Cain & Cain Abbeys
Though I have not heard it personally, the Glow Audio Amp 1 gets
rather rave reviews and supposedly has much more drive that its tiny
wattage spec's would have you believe.
I can personally, very highly recommend the Sophia Electric Baby amp,
the thing just rocks, and is really nice looking. It says 10wpc, it
sounds like alot more, though it is not a single ended design so some
of the SET magic is not there like in a 300b design.
The Baby is a tube amp. done right, it really is great sounding.
