This is my first post here, it's great reading the discussions.
I've been using Audirvana for several years, and d/l vers. 3.5.9 the day it was released. Love the sound. While I really like the new look overall - and great mini player view - I want to point out a couple of things, including a consistent CRASH.
My system: 2010 mac mini, 2.4ghz, maxed w 16GB memory, running El Cap. Audirvana setup is simple, using built-in output direct to my receiver, no DAC. I do not use Itunes integration or Tidal, nor do I use playlists. I use album view, separated by genres
