I own a couple sets of Logitech Z-5500s, have owned Klipsch and Creative in the past. I hear people talk about connecting PCs to Home Theater systems and about how much better the quality is. A lot of PC owners out there are confused by this, thinking they're limited to "computer" speaker systems; wondering how to choose wisely and whether there will be some difficulty in connecting PC and HT gear. So on the HT front, can some people in the know suggest good alternatives to the well-known and popular PC surround sound setups from Creative, Logitech, etc. and clarify anything that those who have only used "computer" speakers should know before buying? 5.1, 7.1, whatever. What would you choose, given a $300 budget to buy a surround sound system for gaming, movies, music, etc.? We're talking both SPL and SQ here. I'm also curious about Z-5500 vs. the Gigaworks S750 if someone has experience with both.
