I have a PS3 (fat) and a Pioneer plasma (720p). I have been using the TV's speakers since the beginning and I think it's time to upgrade. The main reason is music, not movies so I don't think I need 5.1 or 7.1 set up. Neither I want many speakers. Just don't care about movies that much.
So, I need 2 or 2.1 setup mainly for music.
The other requirement is size. I want the whole set up to be as compact as possible. I understand that speakers need to move a lot of air, so I will consider floor-standing speakers but would really prefer shelf-size ones.
The amplifier. Or decoder. Or that thing that drives the speakers. Ideally I want a small unit with HDMI pass-through so I can connect HDMI PS3 to the unit and the unit to TV (I have PS3 connected to the TV via HDMI). I want to minimize number of wires I have to run. I really don't care if it has CD player or not. Also I think I can use PS3 optical output to the amp and HDMI to the TV -- perfectly acceptable.
The subwoofer. Optional. Preferably wireless.
The room. "Acoustic nightmare".
Price. I really want to stay under $500. Or less.
