I ordered the Sound Blaster OMNI USB sound card for my late 2013 13" MBPr. I would like to know if anyone here uses a USB sound card on their mbp's and if they are worth getting?
I have the xonar u7, which I got for switching between headphones and speakers easily. For that reason I think it is worth getting. Otherwise in terms of quality, MBP's come with a pretty good DAC inside already.
