So far VERY impressed with price, ease of use, build quality, and amazing sound. Worked without any setup or additional drivers - plug play - on both Windows (Win10) and Linux (Zorin - Ubuntu Based). On Linux (maybe Windows), you might need to try different output devices in your player's settings (in my case the Jellyfin Media Player Client) for the output. I had to manually select DAC01, USB Audio/IEC958 (S/PDIF) Digital Audio Output in the client's output settings to get the full 96k audio out on Hi-Res files. Audio was coming out before, but after selecting this particular output device in the dropdown list the 96K light came on. Only con I can think of, while the status lights are really handy, they are blindingly bright. For the price, everyone should have one of these handy DAC's for gear testing or daily use.

Hooked up my M audio powered studio monitors to my power mac pro Sounds great!

Plug and play, good sound quality.
