I am looking at buying new speakers for my computer. I am tempted to buy the Klipsch ProMedia 5.1 but then also thought about hooking up a stereo system (which I can get off ebay for about the same cost). I am just wondering if you guys have any input, ie the quality, what I'll need to hook up a home theater to my computer(receiver...and speakers that it?) What are the advantages and disadvantages. I can get for example the Sony Dream System for $330.

Please help, thanks
