if searched through the net and not found a definitive answer to this. being a grateful dead fan im interested to know it its truly lossless as FLAC and shn. ive heard that the bitrate is appr. 820 and it is much lower than wav/aif. but how can we test to see it this _truly_ is lossless and not just a AAC encoded at a high bitrate?? this is very important to many live music fans how trade music.
