During a black friday a few years back I got some great deals; however, I didn't think too much into sticking with one brand. Anyways, I bought:
Fronts - Klipsch Icon VF35s
Center - Polk Audio CS20
Surrounds - Polk Audio Monitor 40 series II
So I read I should have all of the same brand. How true is this and if I should, which components should I take out?
