I've prepared 6 of my AIX Records native 96 kHz/24-bit PCM masters as A and B versions. One is the original high-res master and the other is a Redbook downconversion. You are welcome to download the files and play them. Please do not share them outside of the group. I'm conducting a casual survey to see if people can detect differences. I don't claim this will be definitive. However, I've always complained that previous tests failed because the source materials weren't actual high-resolution files. This removes that flaw. These are the real deal. The conversion was done using triangular dither and noise shaping.<br>
