Even you will find it hard to distinguish acurrately and reliable
between 256k mp3 and cd, I think.

I'm more into Scotch, but I know what you mean. :-)

The article is available in german at

The interesting sentence is at the end:
<german>
Unsere musiktrainierten Testhörer konnten zwar die schlechtere
MP3-Qualität (128 kBit/s) recht treffsicher von den beiden
anderen Hörproben unterscheiden; zwischen MP3 mit 256 kBit/s und
dem Original von CD hingegen ließ sich im Mittel über alle Stücke
kein Unterschied erkennen: Die Tester schätzten MP3/256 ebenso
häufig als CD-Qualität ein wie die CD selbst.
</german>
<english translation=babel>
Our music-trained test listeners could differentiate the worse
MP3-quality (128 kBit/s) quite accurately from the two other
hearing samples; between MP3 with 256 kBit/s and the original of
CD however on the average no difference showed itself over all
pieces: The testers estimated MP3/256 just as frequently as
CD-quality as the CD.
</english>

Best regards
