The tech went through the amp again and did a couple of things which I'm very happy with. The daisychained grounding was reconfigured from one to two points, and he added a small amount of additional filtering. To counter any potential stiffness caused by the extra filtering, the amount of negative feedback was reduced. The amp runs very quiet now and sounds beautiful. After the Jensen P12Q has had some time to break in, I'll decide whether to keep it or try a ceramic, depending on how much the bass response increases.
