Jea48, thanks for the report. My feeling is that if my friend doesn't see what CD I'm putting in (he didn't) and the equipment was exactly the same each time (it was) then it means something, at least. No, it's not a double blind A-B or A-B-X test, but I'm not sure in a case like this it's necessary. As for the Clarifier possibly doing something to the volume, maybe that's part of the point: if the Clarifier actually does something to CDs that causes the volume difference to be on the order of .2-.5 dB (based on my experience around the point where some people can reliably start to tell a difference) then it must definitely be doing SOMETHING to the disc! If that's all it's doing then somebody explain HOW?!
"Bedini Ultra Clarifier", does it really work??
I got into a pissing contest over this question on another forum site. I would like to get opinions from those of you that have the Clarifier or even those of you that have heard a red book CD spun on the Bedini Clarifier.
Set up,
When I clean a red book CD, with the Clarifier, I always do both sides. If my memory serves me right that is what the instruction manual says to do. I also let the CD spin the full 45 seconds on each side.
I contend the Bedini Ultra Carifier does indeed work. How it works I haven't the foggiest idea.
The sure way to prove it works is to take two red book CDs of the same artist and Title. Listen to both to make sure they sound the same. Spin one in the Clarifier and do an A/B comparison of the two discs. Let me note here I realize that not all CDs are created equal. If a red book CD already sounds good thru your loud speakers then the clarifier will not make a difference. Or very little at best. But to the other extreme if a CD sounds compressed, bassi, bass loose muddy, highs rolled off, a dead sounding CD, The Clarifier will make an improvement.
Thanks for your input.
Jim

Jea48 ... you can always tell a Pioneer by the arrows in his back Here is a cut and paste from a 6 Moons Audio review of the original Furutech RD1 ... maybe I should send a copy to inpepinnovations@aol.com From the 6 Moons Audio article Furutech claims that impurities in the weak-magnet 99% aluminum alloy of any CD's storage side contain strong-magnet elements of iron, nickel and cobalt -- as does the ink on the label side --that are inductively magnetized while repeatedly spinning inside a player. This is said to inhibit the laser's ability to pick up signal and instead triggers the error correction interpolation mechanism for reduced S/N ratio. Unlike the Bedini which actively spins the CD over two beams, the Furutech RD-1 (and its replacement, the RD-2) use a powerful ring magnet. It first ramps up voltage to magnetize the CD resting stationary above, then reverses polarity to demagnetize the charge in what's referred to as a "loop ebbing" process. |
This is a link that both i and Geoff Kait have posted here previously. http://www.physics.umd.edu/lecdem/services/demos/demosk2/k2-46.htm As to the Bedini, i've found that it basically "blackens the background" of the disc i.e. lowers the noise floor. By lowering the noise floor, resolution is increased and small details can be more easily discerned. It is a subtle difference and is far from permanent. Those using the original "hand held" Bedini Clarifiers need to "demag" the disc for a relatively long period of time. Given that you have to manually hold the switch, it is a nuisance. When i purchased an Ultra Clarifier and heard the results / saw how long the automatic sequence was, i realized that i wasn't running the hand-held Clarifier for a long enough period of time. As a side note, i regularly treat the cd tray on my transports / players with an anti-static spray. I first spray it onto a soft cloth and then wipe it onto the tray. I absolutely DO NOT recommend spraying anything directly onto the tray or into the player itself. Sean > |
