Reminds me of one time in the 1980s when one audiophile doubter ran a test where a rotary switch was used to select between a high end solid state amplifier, a McIntosh tube amplifier, a Carver magnetic amplifier (actually not a true magnetic amplifier but used unusual power supply designs) and a mid range home quality receiver all hooked up to a high end CD player and pre-amp with the amplifier output feeding a bank of headphones.
Oddly, most of the golden ears crowd could "hear" and commented on the differences in sound between the four amplifiers. The humorous part was after the testing was done and the comments were made, it was revealed that the switch did nothing since all 4 throws were connected to one amplifier. You did get a momentary interruption as the switch was turned but that was all that happened.
Anyone else seen a CD Stop Light marker pen for a mere $24.99? You ran it around the edge of the CD to reduce reflections and improve the sound. An appeal to the crowd that couldn't tell the difference between digital and analog.
