Or, if you want to go for a less expensive model, get a Sherwood 6105 5.1 reciever at Outpost. (77$). The 6015 has, in addition to 5x 100W+1 (unpowered) subwoofer out, 2x coax S/PDIF in (the type used by most computers), 1x optical S/PDIF in (a.k.a. TOSlink), and connections for any piece of home theater equipment imagineable. I just got mine, and it is comprable to the Klipsh Promedia 5.1's, except that I only paid about 130$ for the entire setup as opposed to about 350$ for the Klipshes, and I can tune in FM broadcasts without having to get any seperate equipment. The built-in DAC is of very high quality, and also works wonders with a SACD player, or so I am told. A good off-the-shelf 5.1 speaker set with a powered subwoofer can be had for 200$, so take a look around; for 60$ I managed to acquire a pair of Advent Legacy 2 bookshelf speakers, high-end JVC rear channels, a Cambridge Ensemble IV subwoofer, and a half-decent KLH center speaker.
