Rowland Model 9tiHC. They are truly differential balanced and thus should mate well with your BAT preamp. I prefer it with battery power supply.
Original Classe Omega. Single chassis, but two amps inside, two power cords, etc. Also truly differential balanced. Weighs 250 lbs. because of all the caps in it.
The above two amps are current monsters, which is the issue here, not wattage. Unlike most monster amps, each actually sounds good (especially the Rowland).
As for tube amps, I would take the 192 lb. per chassis CAT JL-1's over anything above, but it is like a classic Ferrari in every respect -- nothing like it, when it runs.
