Maybe you are thinking about gaussing youself and not degaussing. Subjecting one's brain to a magnetic field can have an clear effect on how on feels. There should be no doubt, IMO, as Geoff has made clear that this has an effect on sound quality and I would agree a profound effect. I rarely would listen to a cd without degaussing. I wish I thought things like this were not important. It would make the hobby so much easier. Tweaker
A permanent install of a Schuman Resonance Generator SHOULD make self-degausing unnecessary .
Too much is never enough
Picture guy, If I understand this response this would mean that you think that degaussing a cd is a waste of time?? If I understood correctly you could be putting others off of a very good tweak, as at least Geoff has pointed out before. It's an obvious improvement IMHO and only takes a few seconds. Tweaker
Do as you see fit. Play safe and have fun.
But:
Until I can figure out or be told a good reason for something like CD Demagnetization to HELP the sound of a CD, I'll pass. What really kills me is that some claim benefit for doing the same to an LP!
I think, for MY $$$, a Schumann Resonance Generator would provide the best return. I can, at least, figure how this can help.

Too much is never enough
Well Picture guy, feel free to miss out. Why you would need a reason why it works is completely beyond me. If you tried it my guess is that you would hear it and like it. There is a discussion I think here on PH started by Geoff on why. Man, I'd like to know why we listen to music when it has nothing to do with basic survival. Musicians killing themselves for years and years to become good or great and for what, food , shelter , water, air? I'd like to know how and why we were put here in the first place, incredibly complex life forms from absolutely nothing. Yeah, right! Impossible. Don't you think that a little strange? Maybe Geoff can shed some light on this?? Tweaker
Should I expect picture improvements from demagnetizing a DVD or BlueRay?
Brighter? More saturation? Different in some fashion?
Music fulfills a cultural purpose. All cultures invented some form of music. Even if it it simple drumming.
Many sacred structures, from Stonehenge to large cathedrals have acoustic properties to which man responds.
My opinion is that humans are programmed to respond to vibrations even below the threshold of feeling. I'm reasonably convinced of the efficacy of a properly done Schuman system.
Too much is never enough
It's my opinion that it a fact that cd's are programed to improve after being subjected to a degaussing magnetic field even below the threshold of our understanding of why. Your Blue ray dvd question is off topic. Do you actually require a reason why for everything before you believe it. This position is utter nonsense. Now to end this you could actually try it. If you don't want to purchase a demagnetizer maybe someone you know has one. If you can't hear it than you can come to any conclusion you want. The doors of perception are not open to all all the time. You can then say that we who can hear it are delusional, subject to the placebo effect, that maybe we can hear better than you, anything you want but insulting those who hear it by demanding a why answer why before hand. Tweaker
So, somebody 'programmed' the CD to sound better after degaussing even without understanding WHY or HOW such a thing could or would work?
And while I will totally admit that many things ONCE beyond the ken of man are now understood and understood well, as yet I have heard NO theoretical framework for such a thing to happen to a CD /DVD / BR.
And yes, I suppose so. In the world I worked in for 30+ years, we believed in Cause and Effect.
The effect NEVER preceeded the Cause. NEVER. But when something broke or didn't work to plan, we didn't have a seance, or Hope it got better or anything else. We always tried to get to first cause. The engineers I worked for when in R+D were always happy to entertain a theory of what was going wrong. Sometimes we were able to fix it. Sometimes the fix was down another avenue. But there was ALWAYS some kind of reason. We could repeat the error by 'unfixing' the process or machine.
Other than your 'perception of insult', did I actually insult you or did I just wound your belief system?
Too much is never enough
If you haven't tried degaussing a CD to see if you hear a (positive) difference, one that people like Geoff and I would like not to go through this life without, a life which has no known reason for existing, than I suggest that you listen to a cd, degauss it, then listen to it again and see if you can hear it, ok little Billy. Wouldn't it be nice to not have to wake up ever morning and wonder why I have to go to work, why there are billions of galaxy's, why there are those white spots on Ceres, why some people don't think that Chet Baker is god, why the moon is not made of cheese, why people like Mozart, why people hate evidence, why do birds suddenly appear, why is there gravity, why do people vote against there obvious self interest, why do people use 54AWG wire for speaker wire, why am I wasting so much time trying to make such an amazingly simple point.
Geoff does get some things right. Like degaussing, purple and black on cd's. If I didn't try the purple and black on cd's, demanded an explanation of WHY purple and black as opposed to going out and getting purple and black and doing an AB test then I wouldn't have know how good it sounded, at least to me and I would have gone though life with significantly less enjoyment of music. Which is what some of us are hear for. Same goes for degaussing. Tweaker
"people like Geoff and I"
ROFLMAO
I have a powerful bulk tape eraser. I've tried degaussing CD's with it in the past, and, although I want to doubt it, seem to hear a difference. I was in an audio club years ago, tried it on another member's CD, and he heard it too.
But what bothers me is the feeling in my hand when I pass the CD over the degausser. Difficult to explain what it feels like, somewhere between tingling and numbness.
The iron in my blood being concentrated into my hand? I dunno.
"You won't come back from Fletcher-Munson curve"-Jan and Dean
I found the exact same thing on all fronts, when years ago Ric Schultz rode my ass to simply try the Radio Shack degausser I had from my days of cassette head demags from the 70s. (I was, as usual back then, very 'resistant' to such tweaks as being 'unscientific".) But Ric, as usual, was right on the money, much to my disbelief.
Yeah, it worked. But that weird tingling feeling in the hand/fingers was the exact same reason I said, "Too weird. Not worth it." Never used the RS device after that, to be honest.
Then I got a beat-up Bedini demag device for free, and decided to re-try the demagging again, and the Bedini did a nice job for costing zero. Looked like shit, but worked fine.
When I got my Cabasse dealership long ago, I was able to finagle a Furutech demagger for a song from a guy I knew, so I have one of those, too. Very nice, and much better than the Bedini.
I was a major league skeptic on this one, until Ric convinced me to finally try the Radio Shack degausser. Still cannot believe it makes ANY difference at all. Crazy stuff, no doubt.
Whoodathunkit?
Strange that it does seem to have an effect on the sound of the CD, which, while it makes no sense, is simply curious.
The effect on my body is more disconcerting. I can't answer for you and your Radio Shack degausser that geoffkait supposes you're feeling because of the vibration. But my old Olsen Electronics TA-147 bulk tape eraser is a table top unit measuring 4.5" x 4" x 2.25" and is listed at 10 amps. This thing buzzes and vibrates, but I'm not even touching it when passing the CD over it, and I still get that odd feeling in my hand.
It's easy to use, and I'd sweep every CD I listen to over it, but it's not worth hand cancer (is there such a thing?) for the subtle improvement in sound.
...the several MRIs I've had over the years haven't bothered me? Now there are some powerful magnets!
The acid test would be to see if you get that same tingling sensation when using the Walker Talisman which is passive. I can definitely feel the physical effects of magnets and even crystals. Funny, it's been about thirty years since audiophiles started using demagnetizers on CDs yet no one has gotten very far in terms of an explanation. Oh, well, a Rolling Stone gathers no moss.
Back during CDs heyday, I remember seeing CD tongs for sale at places like Audio Adviser, etc. They reminded me of a pair of plastic kitchen serving tongs, except that they had a molded tip which fit inside the CD center hole.
The idea (supposedly) was to help keep fingerprints off CDs, but I'm betting it caused a lot more dropped / scratched CDs then it helped with fingerprints. I thought about getting one to keep my hand further away from the strong eddy currents I was experiencing while holding the CD close to the tape eraser.
As with all things audiophile , these things were exorbitantly priced for what they were. Since I'm primarily an LP guy, I simply skipped "treating" my CDs with the tape eraser, and stuck with a CD Stop Light paint pen and their glow in the dark disc.
But speaking of LPs, I've read similar (though less frequent) claims for bulk tape erasers making improvements there too. That's even more strange, since there's no metal at all involved
Wait'll they get a load of this back in Des Moines.

Best tool to use when you want to Zappa CD!
Well, it does vibrate, the Radio Shack bulk tape eraser. So not surprising you felt tingling.

Thing about magnetism is that it can repel as well as attract.
Thank goodness for that, right?
