or get the logitech z-680's. Its the precursor of the z 5500s. I have the z680's and now adays you prolly can find them in your price range new. It has DD and DTS decoder and they are THX certified. Wireless remote, amazing bass. My roomate got the z 5500's after he was blown away by my 680's. I have to have the highest quality, and the 680's/5500's are top for the price.
680's are in almost all respects the same as the 5500's just $70 cheaper most places.
