Alan,

Thank you, this is helpful. My Yamaha RX-V2400 should be here next week for the HT- so I'll be able to play with the surround options and see. The upcoming Arcam AVR 300 would be a significant step up for the music room, should I want to go that route, and it will allow bi-amping the mains with two of the seven 100watt/ch amps built into it.

I hadn't realized that PL II was in essence a restorative process, that is good to know.
