While avaserfi's recommendations of the CBM170 speakers, stereo subs and a DCX2496 are of value, one thing that must be additionally considered is that the average surround receiver will not allow proper use of the DCX processing unit. This is because the DCX must be inserted between both the sub amplification stage and main speaker amplification stage. Doing with with separate power amplifiers is easy. The problem, of course, is cost. You would have to buy a separate power amp in addition to the surround receiver, and use the surround receiver as only a pre-amp unit(assuming it has pre-amp outs). If you only wanted stereo, then stereo receivers are fare more likely to have a bypass loop(pre amp output with direct amp input that can be used simultaneously).
