That's very impressive. What differences did you hear?

I think I found out most, if not all files with the help of some measurements.
- not all files seem to be accurately level matched (some DAPs in particular are slightly louder than the source file)
This test is about audibility.
They're level matched within 0.02 dB.
The iPod is louder than the original by 0.23 dB on the right channel, and by 0.07 dB on the left channel.
Please publish positive ABX logs of a 0.23 dB difference.
Also, Replaygain finds a 0.01 dB difference between C and G.

stv014: was that really blind? You analyzed the file first and you were aware of frequency reponse variations prior to your listening test. Also, did you set the number of trials to 15 before starting, or did you just stop when you were satisfied with your score?
I corrected the channel imbalance on C: download C2.flac.
