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."Ā 

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?

Millercarbon brought up springs again after I asked the forum this question.https://forum.audiogon.com/discussions/what-your-choice-speakers-with-spikes-or-speakers-with-a-vibr...

I was a newbie and was struggling with being nice to Miller or clawing back. Iā€™m still able to post on the website so I guess that means were still friends...? Iā€™m sure if I flew up into the great Northwest to hear his system he would invite me.šŸ˜€šŸ˜€

Of course you are invited. Half an hour from SEA in Redmond on Rose Hill where the standard fare is Deschuttes Black Butte Porter with ribs. Rib eye with cabernet sauvignon on request. Come check it out.
