Hi Scamp! Welcome to Axiom forum!
Thanks!
It's a divided room. 22'x14 for the theater area with a half wall into a similar sized space.
You could actually try the 3311 WITHOUT a power amp first, then if you feel you need an external amp, go for it.
I'd have no idea if I need the external amp at all, assuming we are talking degrees of goodness. I have no real point of reference since all I have now are the speakers built into the old TV. Plus I need a way to decide if I'm better off with the 4311ci over the 3311. Unless of course I looked at the 4311 with the amp.
While we are on the subject, obviously there are amps with a much higher price tag than the XP-3 what do they buy? Just more power/volume?
