I actually had one of the early Bybee power conditioners back in the 80s. I honestly could not tell any difference. Since I bought it used at a relatively low price I had no trouble selling it at no loss.
The Ultimate in Smoke and Mirrors? BUT...
Because I am an incurable tinkerer and my local distributor had a sale on, I recently purchased two Bybee "Quantum Signal Enhancer".
Has anybody else explored, with their own ears, this device? I'm not interested in theories, only personal experiences.
BTW, I've just ordered three more...
(Thank you in advance for your contribution.)
