I can guess the background (in methodological terms) to the test you cite,
and I'd happily it with you here or elsewhere.

It's pretty simple. We lined up the highest quality live and recorded analog
audibo sources we could in one of top recording studios in the region, and
compared a short piece of wire with a device that put the audio signal into
CD format and then conveted it back to a regular audio signal. We found no
audible difference, using a variety of musicians, audio engineers and
experienced audiophiles as our listeners.

I also have a few issues with method mentioned elsewhere in this thread.

What are they?
