Belles research?

David (Belles) makes wonderful sounding gear. Flies under the radar for some reason.

I was never a Belles dealer, but I’ve owned the 20A, 21A Auricap, 22A preamps and the 150A Hot Rod, 150A Reference and 350A Reference amps. I still have a 150A amp.

Have always lusted after either a pair of MB200 Monos or the MB500 Mono or Stereo amps.

I found a 150a for sale and might consider it because the 250 was delivered today broken. 😐

Greetings V sorry it arrived damaged
 the 150 A is a bit newer and also capable of superb performance. If reasonably priced I would grab it
Ask the guy selling the older unit if he can get the amp to my tech we can  get it going again.  Where are you located?

It's on the way back to the seller for a refund. There is a version 2 150 A? Do you know of any differences? Thanks!

IMHO, the 150A is a much better amp than the older 250.

The 150 came in an "A" version and a HOT ROD version in addition to just the regular 150 original issue. Try to find the "Hot Rod" version if possible. It’s a killer amp.

The 150A, (and 350A) REFERENCE amps had a version 1 and 2.  The REFERENCE series amps had about twice the voltage output than the regular versions.
