I have the older model Bybee Ultra-Quantum Speaker Purifiers, and I have found the same results on my system, as the reviewer found on his.
I had to buy these "blind" because I could not find any first-hand knowledge about their use anywhere, when I got mine. I finally just bought them on "faith" that the idea sounded good. When I got them and put them on my speakers, I found that the music just sounded more "right", and made the whole musical presentation sound better, and more coherent, than without them in the line. I continue to use them right up to the present time.
I have heard some mention of people not liking them, for various reasons such as "collapse of soundstage" and "image problems" but I experienced no such maladies, and had only very good results. In fact my soundstage widened and deepened, and imaging was even better. I can only conclude that there was something inherently wrong with another part of these other user's systems, that was magnified by the insertion of the Bybees. My system is very simplified, with minimal signal path and equipment. Also, my system is extremely revealing of all sonic artifacts, and a problem of this magnitude would NEVER be masked on my system.
So, to all interested parties, from my experience, I would recommend them highly.
