Using it for 1 week only, tried I2S and TOSLINK output on headphone DAC/Amp with Foobar and Tidal on Win11. Driver installation without problems, output to the interface showing on the list. Sound is very good, clean and spacious. On few occassions short noise when PC loads a big piece of software, most likely nothing to do with the interface itself. Overall - too short experience to be decisive, but so far so good. With driver installed the interface works out of the box, provides multiple output options, everything as described on Audiophonics site.
