I've got my unit, so time for testing. First batch are tests when connected to RME ADI-2. In REW FFT tests there is nothing to say - performance over coax and toslink is the same and equal to Mini. My measurements include sine 0 dBFS, j-test, SMPTE and sweeps, all in 48kHz and 96 kHz.

Thanks - very nice testing.
it seems that the pro is slightly better overall than the mini then….
Have you tested the spdif coaxial output with the volume regulation ”on” ? . How is the comparisons with the digital volumeregulation at - 20 dB compared to 0 dB ? Does the WiiM pro resample everything to 48 kHz If using the digital volume control through the spdif outputs ?
How big are the digital volume control steps through the spdif output ? 6 , 3 or 1 dB ?
The eq section seems broken and thus useless, and I have a suspicion that the digital volumecontrol is in the same chip…. (?) But I might be wrong.
( Why Im asking all those questions is that this player might be a perfect digital streamer and preamp for us who owns loudspeakers with digital inputs . And maybe the spdif quality is better than the Yamaha wxc50 when digital volume control is enabled, ie is not resampled to 48 kHz. )
