I’m afraid there’s more to it than just cleaning and taking care of the CDs. That’s kind of the whole point. It’s because the REAL CD treatments, you know the ones, Optrix, Liquid Resolution, Auric Illuminator, Jena Labs, L’Art du Sond and a host of other sprays, liquids and enhancers actually IMPROVE the sound, not just clean the CD. Hel-loo! And the fact that they do improve the sound DEMONstrates a couple things - (1) CDs are not (rpt not) “perfect sound forever” and (2j even through the physical data on the CD cannot be altered the reading of the data by the CD laser can be improved. For starters the polycarbonate layer is only around 90% transparent.

There is a whole ritual I perform for the CDs in current rotation. It is rather effort intensive and time consuming. I will absolutely not listen to any CD without a minimum amount of treatment. The Full Monty includes home freezer two days, full coloring of the disc, including data side, black tape stiffeners on label side, Liquid Resolution spray, and some other things that are beyond scope and better left unmentioned.
Pop quiz: do they really use mold release compound in the manufacture of CDs or is that just an Old Wives Tale? |

That’s not what I said. When you pull a car and measure the force what are you measuring? What is it made of? Answers at 11.

It’s made of nothing. It’s a force. When you measure magnetic field you measure the strength of the field. You can forget about everything else. When you pull a car with a rope what is the force composed of? Nothing.

Actually, I find him trite and defensive. He could have explained that the atoms of magnetic material like magnets are aligned N to S or whatever and that nuclear forces are the STRONGEST force or whatever. Whereas as gravity is the WEAKEST force. This attitude of his is why he was ostracized when he was a member of the Rogers Commission investigating the Challenger disaster. I knew the guy who ostracized him, who was the director of the commission.

What magnetism is composed of is irrelevant. All you need to know is that demagnetizing CDs or LPs improves the sound, or interconnects. So I guess we can close this case.

The first article posted by Rodman99999 stated the relationship of photons to electromagnetic waves as succinctly as I've had the fortune to read.
>>>>>The article, well forum actually, might have seemed succinct to you, but that doesn’t mean it was correct. It was someone’s opinion. Just some guy.
If the magnet is not moving, then the field is stationary, and there are no photons. Wiggle the magnet, and the field wiggles. If some of these wiggles propagate away from the magnet, then those are photons.
>>>>>As far as your understanding of wiggles moving away from a moving magnet being evidence of photons, well, I’d say that’s pretty absurd. In my opinion, of course. It would be unlikely you could see a photon moving. There are no slow photons.

Just one more thing. The web site you linked to edu Illinois Physics forum of some kind, as I recall, made some statements that magnetic fields were composed of photons. Since magnetic fields are stationary how can they be composed of photons that move at lightspeed?

Hey, I was just going by what you said, which was:
“BUT- given that everything in the universe(including photons), either consists of or has(depending on your favorite theory), an electromagnetic field....”

It wasn’t meant to! BUT- given that everything in the universe(including photons), either consists of or has(depending on your favorite theory), an electromagnetic field, none should be able to unequivocally state, that magnetism would/could not affect the typical CDP’s operation, in some audible way. No one has all the answers!
>>>>Well, actually not everything in the universe has an electromagnetic field. Such as acoustic waves. But more to the point, magnetism doesn’t. Magnetism is measured in Gauss. I.e., magnetic flux density. Electromagnetic fields and waves are measured in something else. Volts/m or Power, EIRP, or whatever. One can build a convincing theory for either thing - that magnetizing the CD can’t possibly work or that it could work. This is one of those situations where the ears decide. You are the decider.

Static charge is a separate issue. Which is why ionizers or anti static sprays are often recommended. But static charge is not affected by demagnetizers. So we still have the dodgy problem of magnetism and why demagnetizing the CD improves the sound. This, ladies and germs, is looks like a real and legitimate mystery we have on our hands. |
It was a simple question. You can’t ask a question around here anymore? No reason to get your panties in a twist.
|
|
L’Art du Son the best by far? Really? Compared to what?
|
OK, have it your way. Light is not affected by magnetic fields. Then how can you explain why demagnetizing a CD improves the sound?

Digital data storage is not analog-like at all! It exists independent of the physical properties of the storage medium! This is the revolutionary change in music storage and retrieval! Analog- like fixes do not apply (sprays, green pens, trimming the edges,weighted pucks, demagnitizers ... ).
>>>>Actually, while it’s true the physical data on a CD is unalterable, the process of reading the data is an analog process, an optical process. And therein lies the problem. Because the laser reading process is not perfect, even with Reed Solomon codes and laser servo mechanism, the physical data is subject to misinterpretation/error caused by any of a variety of things, vibration of the CD transport, background scattered laser light, magnetic fields, static electric charge, and others, even the color of the CD label.
Don’t be a digital denier. Join the thousands of happy campers who use vibration isolation, coloring of CD, beveling the edges of CDs, demagnetizers, static charge neutralizers, CD sprays, whatever they can think of to improve the sound. Don’t be an ostrich.
Don’t be a cube, rube, go ape!

I was unaware people could negative IQs until you showed up.

You have the number 2 on your mind.

Funny, but in a demented 12 year old kind of way. |
All the lonely morons. Where do they all come from?

Wishful thinking? Feeling itchy?

There was a CD treatment shootout quite some time ago. Lotions Eleven by the illustrious Clark Johnsen in Positive Feedback. It might have been updated to Lotions Twelve. Kind of been a while. 😳 I’ve had a lot of em over the years, Liquid Resolution was Top Dog, and would you believe I stumbled on my stash of Liquid Res just last week? Oh, my! I didn’t get off on Essence of Music. Optrix is OK. Jena Labs is very good.
