“At the time of it's introduction in the early '80's the B-2x was Yamaha's TOTL amp, with an msrp of $1500. The B-2 is nicely built but it's not in the same class as the B-2x. The B-2 however does have VFET magic. If I had to choose one I'm not sure which it would be. “
Not in the same class? The B2 Definitely not in RMS
I think its worth considering,
In regard to design premise, now in fact the B2x was released in late 1986 in AU and it was a product design of the 80’s whereby a lot of manufacturing had changed from the B2 which was a 70’s design : but a newer design doesn’t always mean better.
For example:
The finer tracking with their soldering terminations use in the B2x are more likely to turn dry : where as the larger solder mass in the B2 are less likely.
The B2x has a lot of solid wiring coupling stages with many small plug and socket assemblies : the B2 has not these to this degree and the designers went to a greater degree to make the B2 much service friendly with pull handles for example on the drive boards and the use of the larger 70’s style plugs on these boards.
The B2x direct mounting of the outs on the PCB then to heatsink : compared with the B2 with TO3 sockets
These are a few examples of difference
