I bought my first Yamaha B-2 in 1980 , new and purchased a second one in 2004, used ,they both still power my reference system to which I compare basic and int. amps that I service on my bench. When they work right they are hard to beat. I put them up against both tube and solid state and there are only a few with the openness ,response and ability to handle great dynamic range. BRAVO YAMAHA
