Are you planning on just listening with Direct or Pure Direct 5.1/2.1 or Stereo w/ Audyssey ? If the former, and since you have ext amps already, why not just get the 3312/3313? I plan on 5.1/2.1 with Audyssey and or Audyssey bypass L/R. So what I was looking for is the best way to get XT32 and dual sub EQ (second sub down the road). The 4311 CI seems to be the most economical way to get both of these features.
