Is 7.1 really worth it?

[gosawx]

I would say it depends on the room, as even tho there are few 7.1 discs, receivers can "extract" a rear-surround channel and do a good job of sumilating a good effect from a 5.1 source.

If your room is still set up as it is in your gallery, I'd say swap the rears out for a set of bipolars, and place them properly to the left and right f your seating position for a better effect....my 2 cents
