ok so now that you have complicated this for me , pls help with simple answers since order going out in 15 minutes!!
1. i plan to use pre-outs from Denon 3808 into NHT P2 - should be ok? i understand the P2 has no volume control but happy to forego that for what appears to be much better amp overall (only reason was poor design - repeat click to switch zones - of Denon remote
2. balanced inputs - what is this? why do you suspect i don't need this (though i suspect you are right)?!
