Clayton Audio Class A


Just curious: are there many amplifiers out there that use a balanced bridged class A design like Clayton Audio?
For both the M300’s and the single box version S2000, Wilson uses two class A 75 watt amplifiers in bridged design per channel. Just haven’t seen that topology spoken of much. They do sound quite good. Would love to learn more about this topology. I know it allows larger class A wattage outputs but still surprised that bridged designs double down. (300 into 8/600 into 4). Thanks for your thoughts about balanced bridged class A topology.

My vintage Adcom GFA-1 uses that design (two bridged amps per channel). 200wpc and a cooling fan at the back because of current draw making it run hot!
I doubt that the Accuphase amps are of the dual-bridged design. This particular design does have a problem with low impedances. Too much current draw - too much heat from the output stages! That's why Adcom abandoned it after the GFA-1 and went back to conventional class AB output stages.Without that cooling fan it would overheat and shut down!
Take two stereo amps, bridge each and you have what the Adcom GFA-1 did with one chassis.
