CNet never ceases to amaze me!! They always perform stupid benchmarks, post useless reviews that don't tell you anything and once in a while, do the ultimately ambitious things-the wrong way!!
Check this out to find out what I am mean.
Full Version: CNet always does the most useless things...
Well, it does say that they didn't tell these 8 people what codec they were listening to, although they did tell them which was the reference sample (the WAV). They used iTunes to encode the MP3's, which is clearly silly albeit valid if you assume they were testing iTunes against Windows Media Player. It doesn't appear to have been double blind (they don't say), although if the guy doing the actual playing was isolated from the people doing the listening, it could still be.
But yes, on the whole, very silly, and their results show the inconsistencies pretty clearly. The lower bitrate files are often rated higher than the higher bitrate ones on the same samples. And all their numbers fall within about a 2 point sample range, roughly, so there's not a lot of variation there either.
In other words, a wholly useless test.

To calculate our results, the jurors were asked to rate each 20-second sound clip on a scale of one to ten, assuming the WAV file was a perfect ten. One decimal point was allowed if needed.
This scale is psychometrically problematic. Each person can attribute different meanings to the scale, what is undesirable on experiment. The scale used in ABCHR has only five points, and each point has a determinate meaning based on the characteristics of heard encoding artifacts. And, if the later is not always perfect (no psychometrical scale conveys perfect results), figure out the consequences of CNET's scale!

No kidding
they aren't the only ones. I love reading useless reviews from sites like Amazon too with the exception of the people who know what they are talking about. I use the blatent bashing of the Rio Kharma 24/7 as a example

although it's odd we thought the 128Kbps file sounded significantly better than the higher-quality clip.
? ummmhhh? next time we should use 128kbps instead of 192kbps
