Does George offer a trial sample?
It seems that if one were to send him identical burned CDs of the same recording, one labeled "A" and one labeled "B", and asked him to treat one but not the other without saying which was treated, then the effectiveness could be tested. Even better would be to do this to two or three recordings.
Then, after listening, if one believes they heard a difference between the discs, a call to George to learn which disc, "A" or "B" was treated, would confirm the listening test (or not).
