I've got an Asgard 3 with the optional internal 4490 DAC addon, which is great, and I'm connecting it to my phone via USB. I'm investigating other sources, chiefly a PC, and I was wondering how I go about ensuring that a given PC (which I don't have in front of me, such as one I'm considering buying) can actually feed a DAC in this manner. Is there a term or a chipset or minimum speed I need to be aware of?
