Hi, For a USB interface that does balanced audio, I've had good luck with the following:
http://www.mcmelectronics.com/product/555-17815 It is based on the TI PCM290x series chipset which I've seen used in other broadcast gear. http://www.ti.com/product/PCM2900/description Admittedly it is limited to 48kHz, but it does work well and at the price point I can't really complain. I've tested it with both straight ALSA and Jack under Rivendell and don't have any major complaints. The one issue that I have run into - some of these units seem to have a phase issue on the outputs. The fix is a simple swap of 2 wires on one of the XLR's with the soldering iron (5 minute fix). Otherwise the unit just seems to function as designed.
