Hi all. This my first posting. I have a Sony 55" HDTV, Denon AVR 1804, the JBL N24 bookshelf surround package, a 10" Dayton sub and the Denon 1815 changer. I plan on getting a pair of JBL E60's or E80's as my mains in the very near future and moving from a 5.1 environment to a 7.1. I know the 1804 is technically a 6.1 receiver but if I use the "B" speakers and sacrifice a second zone, I can utilize the 7.1 channels. My question is this: will the 1804 be able to handle it? I'm fairly new to the HT world so my apologies if this is a pretty basic question. Thanks in advance for any advice!
