Quote: "Psychic: What is the difference of employing some type of "filter action" in a power cord or putting it inside of a fancy box ?"
Answer: There is no difference--theoretically.
Now, by having one component perform *two* functions, try to evaluate its sonic signature and its filtration performance at the same time. I like my filtration happening elsewhere...

From what I understand there's some speaker cables that filter stuff. I think Empirical Audio does have such designs and has an explanation in the website (www.empiricalaudio.com). There is an explanation of line noise generated *within* the wire in the Bybee website (www.bybeetech.com). I went for the Bybees because Dan Wright insisted they were necessary and I accepted what the Bybee website exposed. I had also done searches on the Asylum and Harmonic Discord. Pretty controversial what I found. Eventually, Dan's posting on this matter in Audiogon clarified me as to why the controversy.
The Bybees proved to work great in my speakers--definitely worth the money. It's good to know effective filtration is happening at the last minute, just before the signal enters the voice coil. I can see that with all the mods my speaker's efficiency increased by about 2dB.
