To find out exactly, one needs to check via a bitperfect testfile, record output, and some file summer utilities to compare and rule out any DSP or whatever interference. The hint I got from the WiiM settings (re. DSP) is disabling EQ and volume, but I'm far from expert on such matters. Seems like a fair question.That’s nothing to do with bit perfect. It just shows there’s no resampling. The two are entirely different things.
