Here is some useful CBF info that Alan Maher sent to me over the holidays while I was contemplating CBF placement options. Thought I would pass this on:
"The CBF works in three different planes. First, the CBF retunes/repitches whatever it is attached to, meaning if it is attached to the main wire bundle it will repitch the frequency which is how it begins to expand the soundstage for audiophile jargon use. Next, placing it on the individual circuit breaker itself is a wonderful place for repitching the application because circuit breakers sound like *&@# and need all the help they can get. 99% of your noise inside the box is a poor quality breaker. With that said, the second stage of the filter is magnetic. Using the natural material we absorb EMI (not RFI) from the application. Stage three takes the EMI and converts it into a negative ion. Unlike traditional information about negative ions and stereo equipment being a bad thing, our method is very natural and has zero side effects. Traditional negative ion generation uses a negative ion generator and this procedure creates a static charge in the air for the conversion. It is the static charge that breaks down rubber in your speakers over time.
