that article is full of fail here is a great quote
"While in the studio, Ward downloaded a track from a recently mastered indie rock album from iTunes. We used Apple's iTunes processing tools to convert the track to a WAV file —according to Apple, it's the same decoding performed by iTunes during playback. Ward then loaded the original CD master WAV file into his workstation. Using his console's A/B listening switch, we both spent time comparing the two tracks."
Really they converted a lossy AAC to a wave file and compared the wave they made from the lossy iTunes file to the cd rip??
