Thank you so much for your reply. As a follow-up, please explain 'keeps changing from class A to class B'? Do you mean the design itself kept changing? Or do you mean that each amplifier would continually change internally from Class A to Class B? I suspect the later because of the following:

The day after receiving the BES 850 amp, I took a warm detailed transparent amp down to our local electronics shop where the owner w/ 35 yrs experience made some adjustments, including bringing the idle speed down to 1/4 volt, but in the end brought home a lifeless analytical cold amp with channel imbalanced.

So I'm thinking the BES 850 design is nonstandard, and I won't be able to find a shop who can fix it unless I find the schematics. So any understanding of how this amplifier was designed may be extremely helpful.

The Streets Electronic Systems 950 uses a fan, whereas the Bipolar Electronic Systems design uses heat sinks. So if I had to make a guess I would have thought that the Bipolar amps were a design advancement over the Streets 950 amp design. So I would have been wrong?
