1. Try SOtM tX-USBexp Audiophile PCIe to USB Audio Card / SOtM mBPS-d2s Intelligent Battery Power Supply. This is the best USB playback I have heard and it works flawlessly. I am using this for about a year now and never had a dropped connection. You can go without battery power supply if you want but since Bricasti needs 5v from USB this is the cleanest way to deliver it.
2. Other option, if you are willing to give up native DSD playback, would be Lynx AES16 audio card going AES connection to M1. This is what I used before and switched to USB only in order to have native DSD playback.
