Interesting idea , acoustic guitar+singer recorded
professionally and then played back in front of a couple
of pairs of ears via 2 different pairs of speakers , in
turn, driven from the same amp and also the live
performer again, for 3 way comparison.
What did the human ears detect, so readily, to
distinguish the live performance?

This is one of those tests that is only interesting if a no differences
result is obtained using sensitive listeners. Any of a million likely
screw-ups, many obvious and some subtle, will give a positive result for
differences.

But there's no way that this particular test can have anything but positive
results, as what the listeners heard via the electronic path contained
doubled doses of room acoustics.

Simply setting up a test this stupid is like flunking an IQ test, let alone
advertising that you screwed up in such an obvious way on TV.
