Another vote for the device Dan linked, heh!, and I fully agree it's twice as effective as the Walker Talisman for half the price. That's not hard to understand. What's stronger, a handheld magnet or an AC powered electro-magnet? :)
WARNING: unplug this thing when it's not in use. Ours heats up quickly whether the power button is depressed or not. It has a thermal shutoff that's worked so far but I'm not trusting that (in a cheaply made device) to prevent burning my house down.
That said, the differences from demagging LP's are clearly audible to Paul and me, no double blind test required. For a mere $100 anyone can try it for themselves. If that's alot of money to you than your system probably isn't revealing enough for you to hear the difference. I wouldn't recommend it in those circumstances.
P. S. It provides audible and visible improvements on DVD/Blu-Ray discs also. The video improvements are measurable with tools as simple as a DVE, Avia or similar video test disc. Wider, flatter grey scale and more accurate color renditions. Scoff and call it voodoo or enjoy superior PQ and audio, we each choose our own form of entertainment. ;)

The idea is to start with the device (powered up) very close to the object. Circle it s-l-o-w-l-y around the object while s-l-o-w-l-y increasing the distance. As the field slowly changes position and weakens, molecules in the object orient themselves randomly, just what we want.
The worst thing to do would be to start with the device close to the object and move it away fast in a straight line or power it off close to the object. That will leave the molecules in the object oriented in the same direction, just what we don't want.

Sarcher30, glad you're enjoying this poor man's Furutech demag!
IME and Dan's it's more effective and longer lasting than a $200 Walker Talisman. Whether it matches the $1800 Furutech is untested, but as they use the same technology...
The usage I described is how machinists demag tools, drill bits, pieces of work, etc. FWIW, it's what my partner (an industrial scientist with a PhD in metallurgy) and his father (a master machinist) both recommended.
Gotta go realign some coffee molecules!
|
Tzh21Y, if you have an opportunity to compare results with the Furutech we'd all love to hear about it.
I can't reiterate too strongly, PLEASE unplug this cheap, made in C***a doohickey whenever you're not actively using it. It overheats quickly, so please don't burn your house down. This is why I haven't openly recommended it.

:-)
My partner, whose brainstorm this was, will be pleased.
Of course he'll just say, "Really? Two electromagnets of similar size powered by the same current produce similar effects? Did you expect otherwise?" ;)
But he'll still be pleased, so thanks for the report!
|
Yup!
DVD and Blu-Ray discs too. If you have a good quality, accurately calibrated video setup, there will be PQ as well as audio improvements. We even demag rental movies. Future renters will benefit without knowing it, can I backcharge Redbox? ;)
|
Doug, I am really surprised to read that your nephew thinks the effect may be to reduce or alter static charge. Lew, I never said anything about static charge. Nor did I quote my nephew. Were you thinking of someone else? |
George, glad to hear yours doesn't overheat. Paul even replaced our on/off switch and it still does, probably a short circuit in the coils... cheap POS!
"Close" means as close as you safely can. A magnetic field obeys the rule of inverse squares, so the closer you get the stronger the effect. I let the backs of my fingers brush the object being treated, so barely a cm away to start. Keeping the LP in a sleeve to prevent scratching is wise.
Moving "slowly" for us means:
- circling above the object at ~4-5 seconds per revolution, and
- receding from the object so that it takes ~15 seconds to get from ~1cm to ~1m.
Paul just mentioned another trick: start with the POS flat (parallel to the object) but gradually/steadily tilt it as you circle and recede, such that by the time you're ~1m away it's "aimed" at ~90 degrees to the object. This is another way to weaken the magnetic field relative to the object, so tilt it SLOWLY. Chanting your mantra is optional. ;)
Pradeep & Peter, we do both sides though I'm not sure why. My guess is that it's less a matter of "sides" than that repeating the procedure doubles the odds of affecting any given molecule. I haven't compared results vs. doing just one side but I don't care since it costs me no useful time. I generally multi-task, demagging one LP while the Loricraft is vacuuming another. Demagging doesn't steal many useable minutes from my otherwise thrilling life.
We demag discs just before we wet clean, on the untested hypothesis that reducing magnetic attractions might aid the cleaning process. That's speculative but if we must demag sometime, why not then?
|
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.

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