Another DAVE owner who has a 12 Core Mac Pro has successfully run DSD files on his DAVE. Hi @romaz, is it DSD64, 128 or 256 with your Mac Pro?
I have on one occasion after much meddling with everything got the DAVE to almost finish a 3 minutes DSD256 song successfully with almost the same spec MBP as yours. But, it paused with 20 seconds to go.
I pretty much gave up with the MBP and waiting for a Sonic Transporter and micrRendu to arrive to work with the DAVE.
For DSD files, I only listen with the Nagra HD DAC.

DSD64 does seem to work fine, even from the little Retina MacBook.
Via my Auralic Aries it also works up to DSD64.
So far haven't gotten my SonicOrbiter SE to play native DSD at all, despite configuring it to do so ... but will have to have another play with that, it was late and I may have missed something.
