See my previous post on this subject. The problem with the basic Amarra HiFi software is it does not support HD (24/96 and above) FLAC playback directly. You need to either first convert FLAC to AIFF or upgrade to the full version of Amarra. In the end I went from Amarra HiFi to Audirvarna Plus to play HD FLAC files directly. To me, Audirvarna Plus was a very good $50 investment.
