I have an
Axiom Audio 5.1 system that's really nice. It isn't the best, but the price was good. The subwoofer is an HSU VTF-3. My receiver is a Harmon/Kardon AVR335.
My speakers are two M80ti fronts (floorstanding), two M22ti surrounds, and a VP150 center. For just the speakers it came to $1965. The subwoofer was about $700, and the receiver was $450. I think you'd need a different receiver, this one doesn't do DVI, AFAIK. I don't remember. But it's a nice set of speakers, and the price was good.
