I embrace both formats, but I bet there would have been a bigger difference had Digidesign not been put in charge of the "simple" experiment. They used a couple of unbiased engineers, why would they use the MOST digitally biased audio company in the world to set up the test? After all, Digidesign sells digital only products, and allowing a seasoned recording engineer (who has no monetary interest in the outcome) to set up the simple test, would have certainly produced different results.
Personally, I would have played an analogue mix directly off of the 2" master through a decent analogue console and then through a nice 16 bit stereo converter (to simulate the conversion process to CD), and sync that to the DAW playing it's own mix out of a stereo pair of outputs with no plug-ins or outboard gear allowed on either mix.
I also noticed that the segment started out as a analog verses MP3 comparison, and mutated into a "some verses were created using an analogue console, and others were digital" comparison.
I'm not arguing in favor of either format ( I use both), but I know that if my clients can hear the same difference that I do, Jean Marie, and his assistant Colin should certainly be able to.
