What's running on your audio server? And why?
My White MacBook has:
- OS X 10.6 (Snow Leopard) with some of its background processes switched off
- iTunes for library management and control via iOS's Remote app
- Audirvana+ for playback. It's the best I've heard
- Audio Hijack Pro - for EQ
- smcFanControl - to keep fan RPM and hence noise down
That's been pretty much stable for some time now.
What apps have you installed or tweaks have you made that I should think about for my audio server?
