Other Notes: "...I would add that the B-2 is one of the most musical amps I ever heard, a pleasure to listen to.

It is obvious that the pesky B-1/B-2 pots and switches are there to serve the marketing department agenda (working on a permanent fix for that) but if you dig deeper under the hood of a B-2, you will find a DC coupled design with minor ancillary but robust circuits to ensure the V-fets do not go to V-fet heaven as easily as they do on the Sony cousins. B-1 is a totally different animal.

These amps are total sleepers and Yamaha gets no where the respect it deserves for what they have created.

Yamaha went to the extent to building new semiconductors never used anywhere, implement them in an amplifier design never "mass produced" before or after. The number of B-1s sold is around ~ 3000, and that is a lot considering that their cost new was same as that of an automobile.

Number of B-2s sold is around 10,000, more than all of its price point competitions combined and competition was no slouch (Sony TA-N7, Victor JM-S7 and even the B-3, its younger brother). B-2 survival rate is also much higher than that of the competitors form other Mfgs. This says a lot about the B-2 since the astute HiFi enthusiast of the 70's had the opportunity to go into a showroom and listen to all these v-fet amplifiers side by side, yet the B-2 outsold the rest by a long margin (same price point)."
