Audirvana Plus with iTunes integration just got a new update today. I eventually came across several bugs with first beta but so far the new build seem perfect. Plays completely in the background, files load quickly, and Apple's Remote apps works flawlessly with it. Also still have option to use player as stand alone. Other nice feature is has setting to turn off Spotlight and Time Machine while using it to cut back on CPU usage. So for now, this is my preferred player.
