What are your thoughts on the "Edsels" of the audio history?


It is a human normal to seek the best, and the world of the high end audio fan is full of that history.  But what about some of the dead-ends/failures?

How about Quadraphonic, Perfect Sound Forever, 8-track tapes, SQ and others in your thoughts/memory?

The Bose 901 has been in production for over 50 years. I would not consider it a failure. No doubt about it , it still sells!
It had a long run, but Bose discontinued 901 production years ago.
What about the anti-static gun?  (It was said to get you high if you aimed it at your temple, but mine, alas, didn't do that well either.)
