I would assume that HDMI (from the PC's graphics card to the Denon) would provide the best sound quality.

An Asus Xonar DX or D1 sound card (used $50), running analog from the Asus to the analog inputs on the Denon, should provide even better audio quality and be able to use the Xonar's Dolby Headphone 7.1 surround sound.
