UIW RLS III, UIW 75, or Polk Audio 265-RT. These aren't all the components, but each would form the underpinnings of the system. Which system is the best for the cost? We are not audiophiles, but don't want to do it again wasting money on another system. At the same time, for an extra 1000 wouldn't mind a substantial increase in performance. However, we can't tell a significant difference among song tracks that are compressed etc. For a sub woofer we are thinking of the Sub Reference with the Amp, however, we are also considering the Sub 10/10 without the amp. If we go with the UIW, is it really worth getting the sub reference with the amp or will the Sub 10/10 suffice with the wiring for an amp to be bought in the future if needed?
