I use Audirvana Plus on my MacBook in my office system and really like it. For some reason, though, I can't get it to play on my Mac Mini in my home system. I'm running Pure Music at home. Both of them are good. I think Audirvana is a little smoother in terms of its functioning (as long as you can get it to work!)
Audivarna Plus
I just downloaded the 15 day free trial and it sounds fantastic. I have been struggling with my digital for many months. Tried many servers with both my Mac Mini and PC. I think this is the one (for me). I would highly recommend anyone into computer audio to give it a try!! No affiliation or financial interests whatsoever.
