Manufacturer's info here: http://www.diyinhk.com/shop/audio-kits/111-xmos-192khz-high-quality-usb-to-spdif-with-ultralow-noise-1uv-regulator-wmanual-power-switch.html

If you just read the parts list and compare, this is in many ways equal to the Singxer SU-1 and superior to the F-1 if you're just looking to get coaxial or optical from USB. With the added 7V linear power supply (the maker recommended 6-7V for best performance), the performance is even better.

A few scratches on the case from different ways I've held down the lightweight unit. Custom shielded DC cable with gold-plated connectors. The PSU is fairly new. I just stopped having a need for it.
