Teo, please reread the OP‘s opening statement and note that he himself is dubious that what he is hearing is an improvement. Meantime, no matter how many ancient philosophers and important scientists waxing philosophical you care to quote, there is such a thing as objective fact. Fact is there are no Ferrous materials in vinyl. Another fact is there are no forces around an LP that could possibly magnetize any Ferrous content of an LP, if there were any. And finally, using a tape head demagnetizer to demagnetize an LP is a tricky business. Others have shown in the past how improper use of a demagnetizer can actually magnetize an object. We don’t know that the OP was using his demagnetizer in such a fashion as to achieve demagnetization. Therefore, we don’t know that any effect he thinks he hears is due to demagnetizing anything. Fremer quoted Furutech’s claim that there is iron in the black pigment in LPs. Furutech has measured a little more than 600 nanoteslas of magnetism in an LP and a little less than 600 nT after use of their demagnetizer. That’s a very low magnetic field before you demagnetize, and a very slightly even lower magnetic field after demagnetizing. Whether that can make an audible difference is up to the observer to decide. And finally, why is it that folks like you who wish to believe in things that for others defy belief are always so angry about it?
My venture into the world if demagnitizing vinyl. Your results may vary.
Ok, I have been using my hand held demagnitizer (tape bulk eraser) on these particular versions of records in my collection that have accentuated treble ( The Who- "Who's Next" MCA masterphile, "Tommy", "Sell Out" , Ted Nugent "CSF" and the Dixie Dregs "Industry Standard" and the initial results are in. YES! a resounding yes. Positive. Eye opening or should I say ear opening. At first I was skeptical having heard about it from a Michael Fremer review about 8 years ago. The curiosity finally overwhelmed me. Boy I wish I had known and tried this earlier. The single best tweek I have experienced bar none. After treatment every note was the most profound note ever struck until the next one and the next one with me anxiously waiting for that next note. It was like analog on acid with me hearing a whole new sonic landscape. I can now imagine how it is justified by spending 3 grand on a dedicated device. My procedure is as follows with a Radio Shack bulk eraser. To protect the record I laid it on an album sleeve with another sleeve on top to protect the record to get as close as possible with the unit. I used the unit as I would on a tape deck with being slow and steady. I also did both sides.
Ok ok I'm being serious now. Back to earth and not the way over the top and dramatic description as the above. I might (BEING THE KEY WORD) might have heard a high frequency mellowing on CSF and the Dixie Dregs. Actually on CSF it was a little more than maybe. I'm a little embarrassed saying that and that leaves me open to ridicule. That perplexes me. I know its far out there in pseudo science land but I think or maybe I thought I heard something subtle. Definitely it's not a slam dunk case. The science states that there is practically nothing on the record that would react to any degree with a demagnitizer. I might try a couple more. I would hope some fellow Audiogoners would have an open mind and see if they have any positive results with the procedure above with some treble accentuated records.
I also have diminished hearing and it was hard to tell.
Oh well it was fun.

Warning. Do not do this with your record on the TT. You will ruin your cartridge. Which you would know.... how? Only if you ruined yours, I would say. Otherwise.... Look at my system. Please. https://systems.audiogon.com/systems/8367 There in image #10 you will see an actual Radio Shack Bulk Tape Eraser sitting in its usual spot on top of my modded power conditioner. Bought in 1993 or 4 its been plugged into that outlet for years because from there it reaches almost all the cables and turntable. Its used not only on records before just about every play but over the cables usually at least once per night and always before playing any of my White Hot Stampers. Its kind of interesting this post of yours because these Radio Shack units are kind of hard to find these days. When I looked last year there was only one for sale on the web, it was $90 (they were only $20 back in the day) and I haven't seen one since. Do you actually have one? Anyway they do work. Mine is used on almost every side, and right there on the platter, and my Koetsu hasn't been the least bit "ruined" by it. Oh well. One more thing- were you writing to inform, or entertain? Its hard to tell if your post is a joke or serious. If serious you ruined it with the fake ruined cartridge story. If a joke, well comedy is maybe harder than it seems, eh? |
Miller carbon. I used a bulk eraser for my experiment. I ruined a Benz cartridge with running a Bedini CD clarifier to close to it. It took a while then the hum increased to annoying levels. I did trouble shooting in my system for 6 months. I switched cartridges and no hum. I deducted it was the clarifier/demagnitizer doing it. |
So you are demagnetizing your copper or silver cables, that also contain no iron? Interesting. Yes, it is very interesting. Mine was bought in the 90's to be used on CDs. Figured it was BS. CDs are after all polycarbonate, aluminum, what's to demagnetize? Even way back then though I had already learned a lot of seemingly crazy stuff actually does work and so I figured Radio Shack, $20, just take it back when it doesn't work. Only thing, it did work. Easy to hear. Friend bought one when he heard how well it works. Few years later someone said it works on records. Here we go again. See the pattern? Instead of dismissing every crazy idea I actually try them out whenever I can. Here's maybe one of the most valuable items of information for an audiophile to know: When you can't get a good explanation exactly why something works, it does not mean it doesn't work. It only means we can't explain it. |
