The Trends UD-10.1 USB Audio Converter is a nice 16/44.1 external sound card and USB-to-S/PDIF converter. I used it for connecting my computer to a high-quality BNC-only DAC. This is NOT the Trends UD-10.1 Lite. This is the full-featured UD 10.1 which has more connection options and superior features (dual digital/analog power regulation, higher accuracy clock). The UD 10.1 is powered by your computer's USB port or you can use the included Trends rechargable battery pack. U.S. sale only, verified Paypal account/address only. No PayPal fee. CONUS shipping included. +2 feedback here; much more at AudiogoN under "fipple8."
