Power ambitions gone rogue – It's Rogue Audio's new M-250 Ultra monos which generate namesake 8Ω power from a six-pack of KT-88 run in ultralinear, about half that in triode. There are rear-switchable RCA/XLR inputs and 8/4Ω speaker tabs. In keeping with the output glass of choice, each mono weighs 88lbs.
