Biggest audio hoaxes


Often when people discuss audio, they talk about "snake oil" or "hoaxes."

It's pretty typical to use the term hoax as a tactic against another who disagrees with one, or holds an unusual opinion or vouches for something which has not been verified. That's not what I mean by a "hoax." 

By "hoax" I mean an audio product or claim which has been pretty definitively disproved. Maybe not to everyone's satisfaction, but to common consensus.

So -- with that definition of hoax in mind, what are some of the biggest audiophile hoaxes you've heard of?

Sadly, the Morphic Message Labels are discontinued. Fortunately, your humble servant millercarbon researches these things saving you untold pain and discomfort.

Morphic fields are imaginary fields of information. What is information? You’re looking at it! Words! What’s on your CD jewel box? Words! You get the idea. Morphic Message Labels cover up the words, blocking the fields, preventing them interfering with your music.   

Yeah I know what you think but no I am not making this up. Read the Teleportation Tweak above. Sometimes called Morphic Fields, other times called Information Fields, probably called WC Fields on one of the now defunct pages. Whatever. He actually sold blank stickers to cover up words to make your CD sound better.

The best one though was also the most expensive. For $1200 he would call you on the phone, and using his magic quantum powers your music would sound better, and fast, fast as your credit card payment takes to clear.

You asked for the biggest hoax, bet you had no idea we had one this big, didya? LMAO!

I don't think you're going to get the temperate responses you were hoping for.  Still, one can always hope...
