Neat App!

Not only will BitPerfect improve the sound quality of music played via iTunes (thanks to CoreAudio Hog Mode support and buffering of the music to memory), it will also automatically switch the audio output device to the respective bit depth and sample rate, and tie iTunes to a specified audio output device! No more manual switching of the main sound output!! Very convenient!

Highly recommended for all of us crazy audiophiles out there! :-)
