Albert, Thank You for reinforcing the "let's keep an open mind" cause here on Audiogon. While aluminum may not be a magnetic property in itself, have you ever built up a static charge by lazily walking across PLASTIC ( nylon, polyester, polyolefin, etc..) carpet and then touched a non ferrous piece of metal ? Now can you imagine "supercharging" your static build-up by rubbing your feet on the carpet at extremely high speed and then touching the metal ? That's kind of what is happening as the "plastic" CD is spun at great speed with a captive piece of metal inside of it. Keep in mind that this is ONLY a theory so PLEASE don't crucify me for it. My observation with the Bedini Ultra Clarifier is that it DOES work. The sound is smoother, offers more detail and has a quieter background in my experience. Then again, this is all subjective and this is only my opinion. Sean
