The organizer of this session had
assembled (with my help) a bunch of compressed files. He ripped some CDs
at different data rates: 32, 64, 128, 192, 384 kbps (MP3) and FLAC. I
supplied some internet radio at 128 and 194 kbps (one of them was a live
concert).

Nobody (except me and one other guy) could really hear any statistically
significant difference. The vast majority of the 15 "high-enders" there
were wrong more than 50% of the time! Most said that they really heard
no difference in anything above 64kbps! They couldn't hear the obvious
compression artifacts in the music at 128 Kbps, which surprised me.

Based on past performance I doubt that a time-synched level matched DBT was
involved. Let's get that cleared up first.
