Well, I've recorded two sets of samples from 24 bit files that were provided by Teddy and by Freelunch. One set is for people who do not have a good soundcard, but have a way to burn and listen to DVD-A sources. The other is for people who have a good soundcard and can use something like PCABX or WinABX to compare two sources and see if they can identify which is which when played randomly
The a-set samples are 3 recordings of each clip. All 3 recordings are done with the same equipment in the signal path, except that 2 are done with one set of cables and 1 is done with the other set of cables (which I will call the odd recording). One set of cables is brand new and the other set is well broken in. The goal is to identify which 1 sample of the 3 is the odd recording. Extra credit if you can identify which cable set was used on the odd recording.
The b-set samples are 2 recordings of each clip. 1 recording is done with one cable set and 1 recording is done with the other cable set.
Both the a-set samples and the b-set samples will be made available soon, probably by bittorrent. There is a problem with the b-set samples because for some reason, they will not play in PCABX. This may be due to the .wav format that they use. When I tracked them out, I used CDWave and used the alternate 24 bit format so that the tracked files could be flac'd. Maybe that's the problem. Maybe they have to be re-stored in a different WAV format so that PCABX can use them. I've seen references to PCABX being used to compare 24 bit files, so there has to be a way to do this, but I have not figured it out yet.
If you want to get ready for comparing b-set samples, then you'll want to read up on PCABX:
