Answering to "buonassi" I suggest to use Geek Perfect from LH Labs which work fine with Sierra and High Sierra. Unfortunately, as today, it doesn't take DSD 256 but for me good registration at DSD128 are just wonderful

Sorry but I don't use Audirvana anymore since I installed on MacMini GeekPerfect (an audio playback application for Mac computers that supports multiple audio file formats, up to and including Direct-Stream) and, as USB DAC a GeekOUT, initially then GeekPulse, all from LHLabs, I am using iTunes as music player which has been fooled by GeekPerfect and the final result is very good from practical to quality point of view ; so far I've been collecting both PCM and DSD files (32/384 kHz and DSD128 the last being the preferred). Considering the price and ease of use with iTunes I don't look further for the time being.

My DAC is DAC1USB from Benchmark Media Systems, Inc and I have no problem at all if I use the Decibel player

I am using a MacBook Pro USB connected to DAC1-USB, when I want to play something I can hear only from the MacBook i.e. no output from Mac's USB. If I use anther player, without changing any setting, the DAC1 receives data. Did I miss something ? Pls help me thank you
