Folks, I have been with Jack Bybee, when the devices even failed to give improved sound quality in the POWER LINE. INLINE is a lot more intimate. Let's get down to basics. First, most people think that Bybees are a fake, and do nothing at all. But, of course, they do, do something! This is not easily measurable, trust me, I have some of the best equipment available. However, they don't always do 'good' for the audio signal. Jack Bybee accepts this, so should everyone else.
