Hi Vince, I'm talking about real class a amps that run full class A. They are Big and heavy for the power they put out but sound soo soooo sweet. B&K amps do not run class A. They may put out a couple of watts in Class a but they are an AB design. The Amp I was using in my 2 channel Rig before my current Sonic Frontiers Power 2 was a Threshold SA4e. This was Nelson Pass's company before he started Pass labs. She was a real beauty and I wish I still had it today. Output power was 100 watts per channel and she weighed in at 98 pounds. The Heat sinks were massive and it had 28 output transistors per channel. I miss that amp. I posted some pictures below. They are not the best quality as the digital camera I had back then was a real POS.
