A nice variation on this theme occured years ago at an AES conference.
The speaker wanted to demonstrate that 'digital' sound was crap, by
using the familiar 'push down the extended arm' test. Test persons 
listening to analog sound could easily resist, while they lost all
force when listening to a digital recording.

What the speaker didn't know was that the PA system used to play the
tracks was fully digital...

Years later the same person was promoting DSD against PCM, by the way...
