Hello,
Does anyone know this tweak and how it really works (in case it does)?
Thanks!

A moving e field produces a b field. Does the device have moving parts? If one isn't careful he might stumble down the rabbit hole of how can a CD have a magnetic field in the first place.A static electric field on the CD perhaps. A static electric field e eliminator. And that's why they suggest using the e disc before every play, since playing a CD produces build up of static electric charge. Final answer.

The contents of CDs are bits, one or zero. Errors are bad, and essentially a fail or not. There is analog electronics needed to detect the signal on the head, but the SNR is usually big enough and ECC usually good enough, then that isn't a problem.
There are also buffering issues also sometimes complained about, and 'timing jitter'. The only jitter that is important is in the D/A converter, everything else is buffered in a queue.
You'll get the best payback to get a really good D/A interface with no ground noise or conducted noise effects.
Lots of snake-oil, I am one of the few who knows, will discuss this, and has no interest in selling or shilling for anything like this. This old Bell Labs engineer (tops, offered for direct Research council funding, but decided to make $1M/yr inst4ead.) knows where the cr*p is, and it is in the D/A and the nonsense that misleads people into wasting money.

That's weird, because I have very good results with both demagnetizer and anti static electric charge device on CDs. I also have good results with the Green Pen around the outer CD edge. I am also the inventor of the world's first and only complete scattered laser light absorber. The Geen pen only affects the visible red portion of the light. But you probably already knew that. I guess different strokes for different folks.Yes, I'm aware a lot of people say that buffers, Reed Solomon and laser servo systems solve all the woes of CD playback. By the time the data gets put into the buffer, assuming there is one, it's too late - the damage is done as soon as the laser reads the pits and lands. If Reed Solomon codes are so great why do they need a buffer anyway? I can understand why they implement buffers in portable players, to eliminate the effects of shock. I was also the inventor of audio's first 6 degree of freedom isolation platform for CD players, etc. a long time ago.

Ans: expectation bias... We all have it, and that is why we have to keep things 'scientific' and truly technical. Metaphysics is so easily misleading.
John Dyson
If it was expectation bias, wouldn't the expectation to be the "damned thing" wouldn't work? Beside I suspect you would be the first to say controlled blind tests are designed to eliminate or minimize bias from the test.Why would you characterize it as metaphysics? There are almost always scientific explanations for everything. The challenge is finding them. That's what the scientific method is for, no?
When you say we need to keep things scientific what it sounds like is you are closed minded and refuse to discuss anything you deem "unscientific." Who made you the guardian of all science?
Allow me to quote a paragraph from Zen and the Art of Debunkery introduction,
"Science seems in many ways to be treading the weary path of the religions it presumed to replace. Where free, dispassionate inquiry once reigned, emotions now run high in the defense of a fundamentalized "scientific truth." As anomalies mount up beneath a sea of denial, defenders of the Faith and the Kingdom cling with increasing self-righteousness to the hull of a sinking paradigm. Faced with provocative evidence of things undreamt of in their philosophy, many otherwise mature scientists revert to a kind of skeptical infantilism characterized by blind faith in the absoluteness of the familiar. Small wonder, then, that so many promising fields of inquiry remain shrouded in superstition, ignorance, denial, disinformation, taboo . . . and debunkery."

All I know is that talking about E's and 'Ms on CDs that aren't really affected doesn't make much sense. (There is some chance of a static charge on the aluminum, but won't have an effect when there are no ECC errors.) There'd likely have to be quite a static charge to affect the ECCd data (the ECC is spread around, so the correction is pretty effective.)
No ECC error changes, then any audible change is impossible. PERCEPTION might change, but perception has a mental component.
John Dyson
I realize it might not make sense. So what? In this hobby a lot of things don't make sense. You say it's impossible. I say it's possible. You haven't done the experiment so I win. Try to be like the little engine that could. I think I can, I think I can....

All of audio is about perception, only partially supported by physical reality. The rest is imagination and processed signals from the hearing process. I do the physics, DSP, comp-sci & pure EE engineering stuff side, and try to avoid anything to do with the variables assocated with the human 'wetware', including the 'transducer', the environment where the transducer resides, and the neural processes including the human mind.
You can say something sounds better, and that is okay. I am stuck with physics so must determine that the difference is in the perception. THAT IS OKAY, that is the way that the world works... I just do the engineering, very difficult engineering. People other than me can do the 'packaging' and 'perceptual' matters -- I don't like to do that stuff, and happy to stay away from those specific aspects of a project (now and in the past.)
John Dyson
I hate to judge before all the facts are in, but it appears you are the victim of the Dunning-Kruger effect when it comes to audio. I don't think I've seen anyone use the appeal to authority quite so much and so fervently as you.
Edits: 07/07/23
I am making no appeals to anyone except the only authority about physics -- physics itself. I am not taking ANYTHING away from your claims about perception.
Egos and secondary agendas become obvious.
John Dyson
What's outside Pleasantville?(Trying to stay calm and keep from revealing he was from the future) I'm from a town where the roads don't end at the edge of town. It's not like Pleasantville. There are some places that the road doesn't go in a circle. There are some places where the road keeps going.
Keeps going?
Yeah, it all just keeps going.
I equate perception with hearing. You are playing a semantics game. When a person listens to music he cannot be aware of subconscious influences on his sensory perceptions.

Never heard of it and likely most here do not know what it is.
Never heard of what?
It is possible to correct the damage done in the digital audio distribution system, but goes far far far beyond something that is easily run on a smaller computer. My 10 core computer grunts and groans undoing the digital 'mastering'. Essentially it 'unmasters' a consistent processing done on almost all recordings.
Anything less is really bordering on worthless.
John Dyson
It looks like it might be a demagnetizer. Like the Furutech. I have the Furutech. It made a small positive difference, but nothing earthshattering.
I wonder what it does?
Lightens your wallet.
is a disc free of fingerprint smudges and dust, a really good dac, and
a really good transport.
Life is hard. It's harder when you're stupid.
