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!
Thanks roberjerman. Good to know that about the earliest Adcom design. I wonder if there are any other balanced bridged class A designs on the market?
Accuphase Class A amps do as well. 8ohm 60w, 4ohm 120w, 2ohm 240w, 1 ohm 480w. Bridged mode, 8ohm 240w, 4ohm 480w, 2ohm 960w.

Accuphase has serious power.


Thanks technik; Accuphase is serious power class A!  I guess what was confusing me about the Clayton S-2000 is that it is a single chassis dual mono class A design with each channel already bridged. (2 x 75 watt class A amplifiers per side)for output of 300 wpc class A into 8/600 into 4.  Essentially two monophonic bridged amps in one chassis.
