Save some money and have Jim Nicholls from JWN amps build you a custom tube amp that will rival amps many times their cost I just got my 6L6 kt88 amp today and this thing kicks some serious ass for 50 wpc and sounds great at low volumes as well. One of his amps were given a stellar review by Lynn Olson from Positive feedback in the latest issue
