I got my Panamax M5510 in and hooked up and am pleased. The unit looks great and works. The filtering is as promised, getting up close to my speakers with the DVD paused and volume cranked and I can tell the noise floor has dropped on the hiss and faint 60hz hum. The TV also appears to be more clear than before.

The main reason I got it is because the Powervar at 12amps was not enough when cranking the system with the 770, but not an issue with the Panamax. No TV screen dimming anymore when I turn it up on some heavy bass laden DVD Audio music.

The meters are cool too, just to watch. My voltage sits still at 120V and with the system at idle, the current is at 5amps and will pop to only about 6-7 amps during heavy passages. When powering on the 770 or the TV (tube) the current meter will spike to 15 and settle down.
