Tweaks such as demagnetizers ionizers for lp's

This topic is really quite interesting, and I am trying to brush up on the physics of it. One further bit of advice that I came across elsewhere was to be sure to turn on the demagnetizer when it is well away (>3ft, according to one source) from the object to be demagnetized. Then bring it in close and do as Doug describes. One source said to move the demag away from the magnet "slow, as molasses in January". I presume the author meant January in a cold climate.

So the contrary experiment would be to deliberately use the demag incorrectly so as to magnetize the LP (in theory; if that is possible). All sources warn that incorrect use of a demagnetizer can result in magnetization, if that is a word. Magnetizing a demagnetized LP should make it sound "bad", if what one is hearing is actually due to magnetism. It would make for an interesting double-blind experiment. Moreover, one could respond to any non-believer that the reason they did not hear a big improvement after demagnetizing is that they did not do it right.

Doug's directions and everything else I read about moving the demagnetizer away from the object slowly, etc, make me wonder about the Furutech. Isn't the Furutech like a big pancake maker? AFAIK, you insert the LP into the Furutech, turn it on, then remove the LP after it is "cooked". The Furutech does not effect a gradual change in physical distance between its plates and the LP surface. Perhaps instead it is programmed so that its field strength starts high and slowly is reduced until the demag process is completed, thereby effecting the same thing as physically moving a demagnetizer of constant field strength.

Lew, your guess as to how the Furutech might function is what I've always assumed. Building an electro-magnetic field generator that fades to zero over a short, timed cycle would be easy of course, especially for $1,800. ;-)

From the object's POV, there's no way to distinguish between the distancing of a fixed-strength field (by the handheld POS) and the attenuation of a fixed-distance field (by the pancake maker). As in astrophysics: is that apparently dimming light source (aka, a "star") actually weakening or is it just moving away from me? Unless we measure Doppler effects we cannot know. For the object, the question of distancing vs. diminution has no meaning except to demonstrate relativity.

Dear Doug, You and Einstein. I knew it.

Hah! More like Qfwfq (Calvino's little protagonist in 'Cosmicomics').

Those are nice and all but first start with as CLEAN an LP as possible. I recommend Disk Doctor and steam cleaning. Even if ou can't afford the Disk Doctor solution and brushes at least steam clean your vinyl using decent (Aquafina or battery) bottled water. You would be AMAZED at the sonic improvement that steam cleaning an LP has. OF course see Charlie Rehm (or posts/articles that he has written) if you do not know about properly steam cleaning LPs.
