I just purchased the following HT components from my roommate who is moving out: 1) Pioneer PRO-710HD (Pioneer Elite 64") 2) Polk Audio reference CC 3) DCM fronts 4) AudioSource 12" powered sub Now I need to start looking at receivers and at least 2 more speakers (if not a whole new set, I know there are some problems associated with mixing different brand speakers). I've invested a fair amount of money so far, so I'm looking for decent quality components. The problem is, I'm not entirely sure of where to begin, since I'm not real familiar with brand names, etc. I do know for the receiver I want something that is capable of 6.1, and the two speakers would be the LR front speakers. Any suggestions or links would be greatly appreciated.
