Yeah, I'm starting to think that maybe this sound card wasn't the best choice. But! It's what I've got. So...
Will the Denon 720 hook up to this sound card and provide me with acceptable surround-sound with these speakers? Exactly what connectors would I need to get the sound card working with the Denon 720 and out to the Klipsch speakers?
Maybe these are all the wrong questions. I'm really, really new and confused with all this.
Here's a scenario: You have this sound card and these speakers. What do YOU buy to get them to work together. Receiver, cables, adapters, whatever. Be specific or I'll just end up asking more annoying questions
