You can also convert your DSD/DSF files to PCM (flac) using the MC convert function and just play the resulting hi rez PCM files. This works if you have a small number of albums in DSD format. Just select the album, right click and choose Library Tools - Convert Format. Set the DSP Studio options to convert to whatever sample rate you want. I think your Devialet goes up to 192 KHz, so that might be a good option, at least for 2xDSD files. Since it is not done in real time, you don't need a faster computer to do it.
Converting DSD to PCM will produce high frequency noise which you want to get rid of. The default filter in MC is 24 KHz @48dB/octave, which I think is too aggressive, especially for 2xDSD. You can find the filter settings in Tools - Options - Audio - Advanced - Configure Input Plug-in - DSD. I turn the filter off and then use a low pass filter in DSP Studio - Parametric Equalizer set at 60 Khz @48db/Octave. Or you can use the permissive one (50 KHz@24dB/octave) in the DSD Input Plug-In setup. If you want to see the frequency spectrum and the high frequency noise in the PCM file, you can download a little tool called SPEC which will show you the frequency spectrum of a PCM file. Audacity will also do it, but it is more complicated to use. I set my low pass filter passed on looking at where the noise started to increase using SPEC. For me, that is usually around 60 KHz. Note that the DSP studio settings used in converting are different than the DSP Studio settings for playback. You need to set the settings in the Convert dialog when converting from DSD to PCM.
