I recently purchased a pair of M3's. I mostly listen to music but want to assemble an economical HT system. In your packeges you combine the M3's with QS4s and a VP100, but for cost considerations I was thinking of using it with QS2s and a VP50. I was also thinking of holding off on a subwoofer for the time being as well. What do you think of this combination - is there any problem? Also, I do not yet have a 5 channel reciever - any advice on what kind of specs to power this system (or better yet a reasonably priced model recommendation)
