Up for sale are two Sonics 600X power amplifiers, manufactured by Bryston and almost identical to Bryston 5B STs. I bought them together with a pair of JBL 4435s from a studio in London some years ago, and as some of you have heard they sound sublime powering those enormous speakers.

Im only selling them because I fancy another Bryston amp, or maybe a pair!

The 5B ST is a 3-channel amp, so each of the Sonics amps has 2 of the channels bridged for 400W into 8 ohms. The 3rd channel is 150W into 8 ohms.

I’m selling them together as the most obvious applications are running two-way speaker designs active...
