Actually I agree bigger can be better with regard to speakers (although not always). Like is often said in audio, there is no replacement for displacement. The system I suggested is quite a bit larger than the Klipsch system anyway, as far as cubic feet go. The setup Imcloud recommended would be great as well, and also take up more space, lol. The nice thing about the Klipsch system is that it is very easy to drive to crazy loud levels even with a modest amp, you do not need a separate amplifier for them at all, or the Ascend or Hsu speakers either for that matter. Anyway, modern receivers are no more difficult to setup than anything Emotiva has available, and they aren't that much different from your Marantz either. They have a lot of features, but you don't have to use them.
