Here's one to add to your list ASUS Xonar HDAV 1.3 Deluxe sound card. So far this is the only place I've found it in the States Lagoom. I haven't tried it yet. It is at the top of my list when I settle on my OS to use it with. Which for me looks to be Windows 7 64 bit or Vista 64 bit.
High End audio card need recommendation
I need a recommendation(s) on a sound card for an HTPC. I would like to have multiple outputs and great sound. This HTPC is going on my stereo rack and I want to be able to plug it into either my USB DAC or preamp.
