I live in Lipetsk, Russia. In July 29 there were IASCA Russia competitions: http://www.iascarussia.ru/news/?id=93 . IASCA Russia solds "IASCA Official Sound Quality Reference Disk"s at that competitions, those with IASCA judge the participants. One of those disk was bought by me. At this competitions i noted that IASCA disks sound worse that participants disks and at steadfast studying at home i discovered that "IASCA Official Sound Quality Reference Disk" was stamped from mp3 source, and even not the good mp3!!! Also this disk has DCP flag. It is 100% true, it is easy to understand when you see on signal spectrogram from this disk. If you need some proof i ready to give it.
The spectrogram from typical mp3 source from IASCA disk:
