I got a good deal on a sound blaster extigy a bit ago. I got it in favor of the audigy platinum due to lack of a free drive bay at the time. At first it had much worse sound than my old live card, but after a firmware upgrade, it sounds great, it has an ac3 passthrough, then you have you choice of toslink or digital coax out. The only problem is, if your receiver doesn't have a user defined crossover, you could find your sub not used for mp3s, in which case, the audigy and the extigy, have 6 channel analog out.
One thing to keep in mind, wish I would have known this before. You can use a mono-miniplug(1/8 inch) to rca connector, then some digital coax wire, to connect anything in the audigy 1, 2 and extigy series up to the coax in your reciever. And if you're feeling cheap, just get some rg6 cable and rca coax f connectors.
