I've had both inquiries here at the forum, and by e-mail, re various Bybee filters. So how about if we consolidate them and discuss them for now in this one thread?
I will later list my observations in my own system.
Jack Bybee uses declassified submarine technology, basically room temperature superconductor purifiers. This approach is a controversial and expensive one. I really luv most of the Bybee stuff in my dedicated audio and home theater system, but the stuff has been quite expensive. I couldn't live without it in view of the improvement I have heard and seen in my system. But I can't say that its necessarily anywhere close to the bang for the buck of the PS Audio Power Plant P300.
What's good about the Bybee stuff is that not only does it work wonders for me; it may or may not work wonders for you; but Bob Williams at www.audionut.com
gives you a thirty day period to return it if you don't like it for the $$. And Bob will give you competitive pricing.
Caveat: If you have significant setup problems with your system, audio or videowise, don't expect Bybee to cure it.
In fact, if you have a significant problem, the Bybee purifiers may help you notice that problem even more. Bybee purifiers are not a panacea for improper system setup. But with proper system setup, my experience is that if you are willing to pay the price, they will take you up additional levels of sonic and video improvement. At least in my system this is what I have experienced.
Also, keep in mind that components and accessories in your system may interplay with Bybee purifiers. I had Combak Enacom AC filters in my system. They seemed fine with Bybee stuff when I wasn't using Bybee AC filters on my Bryston amplifiers. But when I added the Bybee AC filters to my Bryston amplfiers, initially I didn't like the sound at all. Then I slept on it, removed the Combak filters, put back the Bybee AC filters, and presto, system has never sounded better! Now that Bybee filters have worn in on amplifiers, I do plan to reintroduce the Combak AC filters and see how it sounds, but odds are that its too much filtering. And I do like the Combak stuff, and its fairly inexpensive, unlike the Bybee stuff, and Combak may be an option for some audio improvement as for many the Bybee stuff just costs too much.
