I agree with ya. I will also ignore , this can't be. Was it the 240V or 120V Beddini, my expereiences show a difference.

"Hysterical". I like that. That's very diplomatic . Considering the possibilities.

Bedini Ultra Clarifier Quadri Beam?
Is this for real or just a cruel trick?
If for real please supply specifications.
Should I wait for the "Magnificent Bedini the great and his amazing clarifier act"?

Hmmm, drop the bomb, stir up the inmates, then head for the hills? Sounds like you've been reading too many JV posts.

But I was wondering...If I were to use this gizmo prior to ripping my CD's to flac for my server if I would notice such dramatic improvements?

Hmmm....how many veils can one lift before we have lifted one too many veils?

It depends on what she looks/sounds like after the seventh veil is lifted...

You can do it yourself and my old Clarifier standard works much better with a 9V battery eliminator instead of changing batteries all the time.

Very interesting, BJH.

So, what does the device do?

Material on this Furutech page give the basic theory which as I understand is basically that a CD can become magnetized due to small amounts of metals, e.g. iron, in the disc's label and aluminum reflective layer which the demagnetizer removes or neutralizes.

Note that Furutech (same link as above) publishes test results they claim illustrates the effect, e.g. before/after CD Read Error Rates data and other tests as well.

Of course the Furutech product is maligned not only for being a dreaded "demag" tweak but also because of its high cost. However it is worth noting that prior to the appearance of the very expensive Demag they produced a product, RD-1 (later RD-2), that was if I'm not mistaken much closer to the Bedini in cost (and certainly in appearance). They published similar test resusts (located within) for the earlier product as well.

Incidentally as wacky tweaks go this one seems to have some legs. I believe demag products go back to at least 2000 and there was discussion of the positive effects of using cheap bulk erasers before that.

I've read Bedini's claims regarding magnetism and always wondered if what they are selling isn't just a very high priced bulk demagnetizer. You can still pick up a bulk tape demagnetizer for around $39.

True,but it won't spin the cd ! ROTFL
Seriously now,the thing works.I can't explain how or why but it works.

Well I got the one I have for $50 so I don't feel terribly out of pocket.

I did experiment with a Rat Shack bulk eraser at a friend's place but got no more than a "feeling" it did something on the CDs we tried; in cases like that if pushed I'd go with "no effect".

That was just before I got the Bedini (my buddy pulled out the bulk eraser after I told him I had the Bedini on the way) and discovering the effect, for me anyway, seemed limited to problem case CDs (e.g. edgy/nasty sounding CDs). I have no idea if a bulk eraser would be as effective (in such cases) as the Bedini.

I do plan to experiment more now that I've witnessed it work with my new CDP, e.g. I'm going to try on some already good sounding CDs.

As for the Furutech Demag I see that as a well-heeled audiophile toy, i.e. for the type that would rather pay $2000 for the Demag rather than look down his nose at using an el'Cheapo Bedini... to say nothing of a bulk eraser!

Did Bedinni make green pens too? Did you ever come across any writeups from teh invetors of teh optical disc medium, PHILIPS, sony just did teh error correction stuff, Philips brought teh CD to Sony, but i digress, nowhere in anything i ever read from Philips in their papers on optical disc technology, did they EVER mention demagnetizing teh polycarbonate discs. Nad, nothing, not even a glimmer of such a prospect. Why then did the great Bedinni and Fu fu tech discover this previously not know to the invetor or the CD, and Laserdisc, Philips. How much magnetizim is bad, how much from teh motors in teh CD drive? Does magnetizim move light in teh wavelengths in teh range that is being used in Cd, what about Blu Ray, different wvelength.....funny stuff, demagnetizing plastic, read with infrared light, where do the magnetizim have an effect? At the pocket book, it's stick to the money and pulls it out.......Do bedinnis come packaged in sealed cases, or show up in horse carts like teh traveling medicine snake oil salesman of yesteryear, next one ya listen to, do it not knowing if you did your Bedinni or not, how long does Bedinni treatment hold up? Funny stuff

Quick update...

I tried the Bedini on a "good" sounding CD, the excellent Kenny Barron's Scratch... no difference. Oh well.

Hey, BJH, do you have one of those old D'Stat guns?

I'd be curious to hear what you think about using it on a CD and comparing effects with the Bedini. I often wonder if things like the Bedini or Furutech "demagnetizers" are really just removing some static charge.

Then again, I would still have no technical explanation for why either "demagnetizing" or "de-stat-ing" would have any sonic effect on a CD's sound!

Have you ever had the opportunity to notice if a "bad" sounding disc is a thing where all discs of that release are bad, or if it's an individual disc thing?

No I don't have one... I find wet washing LPs on a VPI 16.5 is very effective at removing static from my LPs (and it stays gone) so I've never bothered with a "D'Stat gun".

I doubt the Bedini could remove static however as it spins the CD at a very fast rate for something like 30 seconds.

The only thing I can say is that don't recall treating my original "Sketches" and it sounded great. Other than that I have no idea.

I doubt that these units work by reducing residual magnetism. The effectiveness would vary based on how much iron, nickel, or cobalt got into the aluminum or gold layer. Since I hear a rather consistent effect on all CD's, I think another phenomenon is in play. What must be happening is the AC magnetic fields from the coils in the Bedini are inducing strong eddy currents in the metal layer on the disc. These currents would then fuse the grains in the metal, resulting in a much improved near IR light reflectivity. Improved signal to noise ratio yields less word clock jitter in the D/A converter. Less jitter means less smearing of fine signal detail into broadband noise. And that's what we, those with intact hearing, discern, a wonderful boost in the naturalness of the instruments and vocals. But be aware that these damag units are better appreciated when the other two CD tweaks are done first: Green permanent marker (or CD StopLight) on the outer vertical edge of the CD, and optical oil (may my old vial of Millennium 2000 last me to the end of my stay) applied to the CD surface. Without these two tweaks, the demag tweak is very subtle as it has to fight through the hash resulting from lack of the first two tweaks.

It's good to see these types of threads come back to the surface. Electromagnetic fields play a huge part in our listening.

If the demagnetizer fused the grains in the metal layer would not the sonic effects be permanent? Besides, the crystal structure of metal implies the atoms are already "fused" by virtue of nuclear binding forces that are 100 times stronger than electromagnetic forces. Nevertheless, this doesn't prevent me from using my trusty Walker Talisman demagnetizer before every play.
