With my 2.0 I will (obviously) be using a computer as a Juke.
This is the sound card that I am seriously giving consideration to: E Mu 1212M PCIe.
It has both balanced/unbalanced/Optical/SPDIF/AES-EBU. So I can alsway bypass it's DAC and go external with AES-EBU. So far people have been raving about the SQ on this. All for under $160 and it give's me tons more options than a USB DAC.
