I searched and could not find an answer. But, I'm wondering if, with the 4520, I can bi-amp my FR, center, and FL speakers and still be able to have 7.1 surround sound? The new Denon has 11.2 after all. Also, will this benefit me in terms of sound at all?
Also, if I'm breaking through the walls to install in-wall wiring, is it recommended to put a set of regular speaker wires as well as bi-amp wires just in case for future technology or if I decide for better speakers?
Thanks in advance.
