Ill say this about that. Ive been running a Nakamichi PA7 Mkll for the last several years, pushing a couple of 4 ohm Montana EPS-2 Loudspeakers. Finally the ole girl gives up a soft on power circuit & Im saving up the cash for the repair. Enter a couple of these Fosi 240 watt mono-amps powered by 2 10 amp power bricks......
Im impressed...incredible sound
