What about Bybee Filters?

Sns, I'm sorry to hear that you had trouble with the Bybees. I've heard these accounts from others, but I did not experience the same result. Mine work great. My system is ultra revealing. It consists of a Sony DVP-S9000ES SACD/CD player direct input to a David Berning MicroZOTL with NOS tubes running direct to single-driver Fostex TL speaker system. This system has huge amounts of "air" and detail. If I lost any with the Bybees, I sure didn't notice it. I specifically payed attention to air, detail, soundstage, imaging, and musically emotional involvement, as these are things I read about before trying the Bybees out. These are the only pair I ever heard, but I like them. With the inclusion of the Bybees, all I have between the output tubes and the drivers is 3 meters of speaker cable(and now the Bybees). I don't know why some systems respond differently than others. It seems strange. The ones I got were the discontinued ones with the Nordost SPM cable pigtail and Cardas spades and Cardas Gold binding posts.

I just tried out a pair of Bybee Quantum Power Speaker Filters that were sent to me by a wonderful member for my evaluation. I just received them and hooked them up today. I spent the next 3 hours listening to music. These things work! My initial reaction is very favorable. Much smoother sound across the spectrum, without any loss of detail, soundstage, imaging, or anything. I will see how they do over a few days time, as far as any changes with burn-in go.

After a couple of days of marathon listening sessions, I have concluded that the Bybees(at least the ones I have) are everything they are advertised to be. This pertains to the Bybee Ultra Quantum Speaker Filters with Nordost SPM Reference tails, Cardas spades, and Cardas gold posts. In my system, there was no down side. The best way for me to describe what it was like, is that everything seemed to get "broken-in" all at once. That smoothing out you get after break-in of a component, is kind of like what happens. The level of smoothness is killer, with all the air, detail, dynamics, layering, frequency balance, naturalness, emotion, and everything still there. IMHO, they are worth every penny spent.
