Does MiniDSP SHD Studio play high resolution files?

I am thinking about buying a miniDSP SHD Studio in order to use both Dirac Live and it’s built in streamer/network bridge. Currently I am using an IFI Zen Streamer, which utilizes Volumio, to stream from qobuz and play files from my computer’s hard drive. The hard drive drive files are accessed via JRiver then played through the Zen Streamer by means of DLNA. There is no problem playing files up to at least 192K PCM and DSD. I have quite a few. I have been told by a MiniDSP SHD Studio seller, that the Volumio version used does not support the playing of DSD for PCM files above 96K without down sampling. Is this correct? If correct, since Volumio supports high rez, can it be tweaked to play these files?
