Dac 8 hi rés file with USB

[BowiePop]

Hello everybody,

I'm very please to write my first post on this Audio Research page!

I just buy a new dac and i choose the dac 8 because i wanted a very good one!

I ve looked at the McIntosh D150 but i found his conception less serious than the dac 8 and i didn't need any pré-amp or headphone amp!

Looked at the McIntosh MDA1000 and the Accuphase dc37 too, but i found them à little too expensive! As the Ref dac also!

Maybe one of you could help me for the USB connection. I use an Apple Mac mini with Audirvana+ and i'm under OS X El Capitan 10.11.3 but i don't find the driver to be able to read hi rés. File at 176 or 192 kHz. I think it's the same problem for the more recent Ref dac owners.

I wrote à message to audio research yesterday, but if you have already a solution!

I will post some pictures soon of my system.
