re: B-2X

Owned most of the best Yamaha amps. B1 B2 M2 M4 M80 M85. Without a doubt...the cleanest most detailed of all. Have to run a fan because of extreme temperature because of its Modified Class A operation. No light show. Have owned one since 1989. In 2018 used prices are over 1500. If you can get a B2 as a spare...good choice too.
