Supertest av Bryston

«If I were in the market for a new amp, I’d buy the Bryston 4B3 without hesitation. It is without a doubt a true classic, continuing in the tradition of the legendary Bryston B amps that came before it. With virtually faultless sound and the ability to drive just about any speaker with ease, the 4B3 may well be the best value today in a high-end, high-powered, solid-state amplifier. To better its combination of power output and finesse, you’ll likely have to pay much more.»  Roger Kanno
