And the baby arrived back home...
Before setting the WOPL to my main system, I'm going to run some sound tests loaded with Yamaha's S4115H. Initially DC offset when the unit was cold was: R = 0.007 VDC, L = 0.011 VDC. When I pushed the mains button the light in my house dimmed for a second - a new interesting adventure... When plugged to my interim setup with 102dB-effective Yammies, no input, amp's pots at max volume - .... dead silence!!! Nothing AT ALL. No buzzing or similar 'effects'.... Excellent!
Then with
"Where Do You Think You're Going?" and "Communiqué" of Dire Straits with preamp 'at 11' I was literally blown out from the room
