In Reply to: Wasn't the comparison between the WAV and the FLAC? posted by E-Stat on April 15, 2007 at 08:40:47:
Further down it states:"I did a file comparison of the .wav files I used prior to burning, using EAC, and from a data standpoint, the non-compressed .wav and the FLAC encoded/decoded .wav were identical!!"
I interpret this as burning 2 identical WAV files, one of which was a decompressed FLAC, the other straight rip from the CD. This interpretation was the basis for my comment.

"I interpret this as burning 2 identical WAV files, one of which was a decompressed FLAC, the other straight rip from the CD. This interpretation was the basis for my comment."This is the case. The files, from a *data* comparison with EAC, were identical. But the straight .wav sounded better than the FLAC compressed/decompressed .wav. And this is the comparison I'm going to run with the ABX, with these so-called "identical tracks" burned to CD-R.
I missed the boat.
Rip two separate files in WAV format and compare those. It could be that any changes you are noticing have nothing at all to do with FLAC (that would be my expectation by the way). Have fun and please report your results.
Just listen to the two bit-identical files you've already got a few more times. Yes, it could be that the conditions of play one at one time and the other at another time could cause differences due to computer response. But over a number of plays the computer factors should even out.Better yet, arrange a double-blind listening session.
Since the files are noting but bits on a hard drive, and since they are precisely identical, a reasonable person would suppose they cannot sound different of playback conditions are the same.

I guess it depends on whether you follow the first or the second part verbatim where there seems to be some conceptual conflict.rw
