I have a Q5 Equi=tech with the 230 30A input power and it has no problem with a tube amp. I have compared with the other 15A circuits in the room, and it is better on the Equi=tech than out of the wall... The Burmester 958 is also a nice unit, but costly. Either of the two I would suggest -- have not tried the Hydra.. Had the PS600 and 1200 for demo and sent them back.
