RE: So what's the deal with CD demagnetizers?

The deal with cd demagnetizers is that a fool and his money are soon parted, or don't believe everything you read, that kind of advice against a cruel world comes first to my simple thoughts.

Jokes aside, one identifies sound only with the brain, and the brain has no self awareness. It decides what it hears , take it or leave it. If it gives you good information, or bad, that is all it knows, and the judgement is always subjective. If you think it sounds good ,it will, and does.

All the charlatan has to do is to make you think the product works, and then it, the suggested illusion, will work.

IN my years reading audio, this stuff comes and goes. It used to be a felt tipped marker was the Cd fixer upper, than a commercial product came out and it had to be a special color. I think you can still buy a magic clock for hi fi nuts, and the same company under discussion here also makes a vinyl (!) demagnetizer, but the special rocks are long gone. All 0f these products were very well reviewed, apparently by idiots. not being able to explain the results of your review by not understanding how the products works is weak, too thin for me and my poor little wallet.

A simple illustration of brain subjectiveness.One can see this easily with eyesight, and optical illusions.

Sometimes, unless it is explained to you , you miss the illusion, your brain doesn't see what the other guy sees, although it is always there for both. It is the brain that interprets the image, and it is always subjective . For instance, when people think they see ghosts, the ghosts wear clothes. How do ghosts get clothes, or need clothes, other than the brain has misfired and generated the image.

Sometimes one will stumble , an error while walking, and you realize you have made an error . The body has awareness, you know when a muscle misfires. Not so with the brain, where the reality is always subjective, and a misfire can be anything. As seen with brain disease, where people live in a long term false reality caused by mental illness, and not a passing simple suggestion, such as ,did you hear that?

If one considers hearing, it does some things better than others. One can easily hear a sound down the street, and know it is around the corner, even with the window closed. One knows this without thought. Pitch takes some concentration, and is often a learned skill.

With these results, It is suggested human hearing developed in the tall dry grass savannas. Where escape was the primary goal, not sonic accuracy. If you think you hear something, you run, to keep off the menu as special of the day. A misfire is no big deal ,not so with the food safety senses 0f taste or smell .

One knows the hand is quicker than the eye, everyone knows the hand doesn't leave the arm, it is just moving too fast for your optical system, so it is no longer visible. Few people consider how hearing works, it is not perfect, and is very prone to suggestion. Consider a smile and a refreshing beverage as a sonic upgrade before buying anything with results that can't be measured or function explained beyond buy it, it works.

This subjective stuff is slightly irritating to me, as is most intentional ignorance . When hi fi was new, test were made, and results were used as a way to understand the product. However, how to measure audio was also new, so some sonic results were not able to be measured. This "unable to know ' because the measures were being developed has stuck, in part because nothing will sound the same at different times, it is up to the brain to tell you how it sounds.
Just like if a guy in a lab coat handing you cheap wine in a fine old bottle and it tastes better.

With cars, performance can be measured. With audio, the finish line is in your head. But you can still buy a turd in either situation. Still, it you think it sounds better , that is your reality. Just don't pay too little or it won't work. I was once cruising the web and saw a single wooden hi fi knob for $450 with the statement is was sonic magic.

IN my personal experience, I was helping a buddy set up his new Bose 901 speakers, a trash design that used multiple midrange drivers only, with heavy signal processing to generate the bass and highs. I was plugging in wires and we were thinking if we could hear anything, sometimes we thought we heard something, as I tried different inputs. Then I plugged into the correct socket, and thinking we heard something was gone, we could easily hear the signal processor and the thinking I hear something was over. Yet for a while there, when we were trying to hear something, we thought we did, kind of, at times.
