Sonic Studio Amarra
Those who follow computer audio forums have probably heard the name Amarra a few times. If you have an Apple computer running iTunes and want to get the most out of high resolution audio, Sonic Studio's Amarra software offers a way around some of the inherent problems when switching resolutions and the way the Apple OS handles audio.
The company's Jonathan Reichbach was at CES to talk about the most recent release of the program along with its mini version. Both versions bypass Apple's Core Audio for "bit perfect" data straight to your DAC. The full-fledged version of the program runs $995 and enables playback of all resolutions of PCM up to 192kHz while the mini version is available as a single-computer license for $295 or available with an iLok dongle (can be moved around multiple computers one at a time) for $395 and supports up to 96kHz audio.
