>>Do you use power conditioning on your Def 4 plate amps as well as the front end electronics?<<
I simply power my Def4 subwoofer amps directly from the wall. I haven't heard any advantage to power conditioning there, and my balanced power transformer for the front end doesn't have the headroom to add them. When I get a higher-capacity balanced power isolation transformer for power amplification, I'll try the Def4 Hypex amps also powered balanced; perhaps that will prove better than directly from the wall.
