Bear is right, its current.
I'll probably get some flack here, but driving Quad 989's the Innersound amp sounded , well, brittle - kinda like a Coda amp, who I think makes it for Sanders...
I've seen the Berning ZH270 easily drive a pair of Acoustat 1+1 Medallion transformer elctroststat spkrs - a very tough load. My advice is get the Berning. No big tube hassles either, run warmish not hot, don't weigh much, great reliability - what do you need to know?
If not, and you like SS, the Sim suggestion above looks good.
