Denon 4310ci: go 7.1 or biamp main fronts?

[Maggot]

Ok, I'll be the first to say I'm not up on biamping/biwiring. From what little I've read, biwiring is a joke and one will only hear a difference when biamping. Now, from what I've read in my manual, what the Denon 4310ci will do is allow you to use the 4310's surround back amps for I guess what would be called passive biamping of the front mains, especially for when you play stereo music. Which would be the better route, get 2 more speakers and have a 7.1 system, although this may be hard and somewhat useless in my 10x11 ft room OR stay with 5.1 and use the biamp option and possibly get better sound out of the fronts? I have Paradigm studio reference 40's in the front.
