Hey I just got a quick question. I know the Denon AVR-1804 has A/B speaker inputs but does that necessarily mean I can bi-amp them to my mains? I've got the Paradigm Studio 20's V.2 and have been running them off a Technics SA-DX1040 that does allow me to biamp and, at least for this receiver, it makes a rather large difference. I just wanted to make sure before I went ahead and bought it. Found a good deal online for about 330 bucks and figure I could swing that to finally replace my technics. Thanks for any replies.
