It turns out running Amarra and Audirvana together can be tricky and lead to frustration. I tried to listen to Rachmaninov 2 (DSD64) last night but it took me an hour to get it working because switching from one player to another made the Audio MIDI settings get all jacked up. By the time I got Audirvana + my DAC working, I was tired and fell asleep during the second movement There was some tense moments before the sonic joy, though. I thought I was going to be one of those guys who couldn't get Audirvana working and that I was going to have to drop more coin on a third player, just for DSD playback. Why can't Amarra support DSD's?
They have said it is in the works...Changing players always causes problems. They all want control of the system.
