Lower budget questions: I just purchased a Sony 55" LCD and an OPPO DVD. Both of these devices as well as my cable box are connected via HDMI cables. Now it's time to deal with sound. The room is 12x12 and given the restrictions in the walls and ceiling, I believe that floor speakers are the only way to go. I will conceal the cabling in some sort of wall mounted racetrack. The "theater" is used 90% for movies. With a budget of $700-800, what do you suggest for a receiver and speakers? I'll add to this the cost of cables. Do I want to limit my search to receivers that are HDMI equipped? Thanks, Dave
