Motorman's New Scam Of The Week - the miraculous Furutech LP Demagnetizer


I thought I would find enough snake oil to write something amusing each week.  Partly because I was busy, and party because no particularly expensive scam caught my attention, I have not nominated a new ridiculous piece of audiophile nonsense . . . until now!  Today's new piece of ridiculous snake oil that no audiophile can do without is the Furutech LP Demagnetizer.  Yes, you had no idea that you needed one, did you?  This little baby showed up for the bargain basement price of $1,845.00 (retail, $2,715).

What does this amazing product do?  It demagnetizes your vinyl, because your vinyl contains carbon and carbon attracts a magnetic charge.  That magnetic charge apparently adds "a layer of grit, glare, and haze," that the LP Demagnetizer magically removes. Of course, once your LP has be run through the Demagnetizer, it will reveal the usual "smoother treble and increased dimensionality," according to The Absolute Sound.  Presumably given a nod to just how dumb that may sound, particularly for $2,715, Absolute Sound actually acknowledges "Nor is it an essential piece of equipment. You can probably get more bang for the buck by upgrading a cartridge or tonearm or maybe even by improving the isolation of your ’table with a device like the Minus K product. But if you’re pretty much set on your analog rig and looking for a nifty upgrade—one, let’s face it, that will likely have your friends questioning your sanity  . .  . then the Furutech DeMag is a no-brainer."  

In other words, if you love your current analog rig as is, but feel compelled to waste money on snake oil that you don't need, the Furutech is a "no-brainer."  Let's put aside the fact that The Absolute Sound's review lacks of any type of double-blind listening study, which is the anathema to snake oil salesman, and lets put aside the fact that if LP's really needed a demagnetizer, you can pick one up for $30.  It is more likely that the purchaser of a $2,715 Furutech is the person without a brain.

6Moons adds to the completely unscientific and totally subjective chorus by saying " It seemed as if analog was even more analog. That little edge on middle and high notes, that glare, was completely gone now. Overall the sound was warmer, more rounded and fuller of color."  Of course -- it makes "analog more analog."  Do we check our common sense at the door when we buy audio gear?  I could never figure out why my already wonderfully warm sounding vinyl had "that little edge on the middle and high notes."  Thank you Furutech!  Now I know.

A voice in the wilderness -- Gizmodo, an organization that does not seem beholden to exaggerated and unmeasurable claims of "making analog more analog," summed it up nicely: "Furutech DeMag Demagnetizes Your Money Away"

As always, if you are one of those people that light their cigars with $100 bills, and think nothing of spending $2715 on something that admittedly looks pretty cool even if its worthless, I guess you may be the target market.  But if you haven't checked your common sense at the door . . .

Carbon black impurities is what the Absolute Sound press lazily tries to blame for magnetism.

Furutech website:
The fact is that pigment added to the plastic during the manufacturing process is the culprit. The minute amount of ferrous material in the pigment causes LPs to become magnetized. Testing at the Tokyo Nanotechnology center with a IHI Gauss meter showed that after an LP was treated with the deMag the magnetic field of the LP was lowered from 620~630 nT to 572~582 nT (nanotesla: a unit of magnetic field strength,1 Tesla = 10,000 gauss)
Earth's magnetic field is 50,000nT.

From IARC monographs

Carbon black that is made from high-sulfur feedstocks frequently contains detectable quantities of extractable aromatic compounds that contain sulfur such as benzothiophene derivatives (Lee & Hites, 1976; Nishioka et al., 1986). Trace amounts of a variety of inorganic elements (e.g. calcium, copper, iron, manganese, potassium, lead, arsenic, chromium, selenium and zinc) have also been identified in some analyses of samples of carbon black (Collyer, 1975; Sokhi et al., 1990; Cabot Corporation, 2005b)
I am skeptical about how trace ferrous metals can get and stay magnetized over a record, or have a geometry that creates a magnetic field large enough to disturb a cartridge. That may be reflected in the nanotesla scale numbers.

The easiest criticism is the price of the unit, which is product of marketing. Consumer behavior is what makes audiogon interesting in lew of actually learning about audio.
