Do you demag or destat your CDs/DVDS?


Just curious about these CD tweaks. The Furutech destat machine is tempting at around $350--I like their products. What is the story behind Furutech's discontinuation of their RD2 disc demagnetizing station? I see it was taken up by Acoustic Revive as the RD3, a supposedly improved version. Did it not prove effective by Furutech's standards, or did they let it go in favor of their much more expensive demagnetizer for vinyl and CD? Just wondering if the RD3 does work to improve sound. There isn't much mention of it in the past few years.

Why so much science when there's a simple math?
All of these articles are just about fraction of % of other materials and minerals inside aluminium???

Folks got enough talent and weed to smoke to write and continue to write hundreds of articles about nothing that makes money and makes product or process markettable and Furutech is one of the champions in this strategy, according to their array of products they sell.

There are certainly other articles that clearly state about bogus tweaks in audio industry(CD demagnetizer is certainly listed as one of the articles' bold headlines), but they're not as massive as marketted reviews and philosophical product articles. Can you do your math?

Might as well grind anchor because everyone on the ship will tell you that it'll work better LOL!

You can also wave the broom over the antenna to blow away EMI and other interfearances. That one also common on military or Navy. Everyone will tell fool to do that!
In the Navy, the 'freshman' were told to grind anchor with file so it penatrates bottom better.
CD's are not magnetic and need demagnetizing just as anchor needs grinding.
Jea48, If your bike has aluminium frame, you can try to attract magnet there and see what happens. Try to attract CD with magnet and see what happens.

Try to offer to private boat owners grinding anchors and you may also find some fools that would actually pay for service!
I have zero practical experience of waving broom over antenna and also have zero practical experience grinding anchors.
Should I have any practical experience demagnetizing CDs and vinyl? Figure out and do ya math.
Sorry Jea, but there's no lab tested evidence at all.
No information is quantisized or leveraged.
Do you or any one here knows of published info with any magnitudes and/or quantities? Any info on flow of the lab test?
Any scientific evidence will help.
Sorry but i wanted to see lab results not review after all.

Can you tell difference between scientifically proven results and reviews? I can build hypothesis out of literally anything, but how can I prove?

Jea, you don't you even know a-bit of science? If not, math is simpler way to comprehend. Check my previous notes.

Did you ever check these values??

It's fake dude.
I'm not ignorant. I fight foolishness and sometimes with humor(or laughs with anger and somewhat courage), because same money fool pays for bogus or fake can be much more useful elsewhere real. Even fool can feel difference between $350 disk demagnetizer and $350 pair of shoes after all(or $350 is too much for shoes huh?).

It's alway's one's call weather one realizes or not who to support -- the bogus factory(ies) or as per example above shoe designers.
Jim,
I read all articles, but couldn't find scientific proof and properly presented magnitudes. The values and graphs are NOT real and I pointed that out prior. It's faked and it's visible even by high school pupil.

Lots of theory why..... scientific proof?

...because I don't like to be fooled by no one including even Allmighty! Lots of theory is never an argument till some of it or all is proven not just by reviewer or bunch of positive review articles or earlier mentioned Him.

Even if something is already scientifically proven still requires a research towards desired results vs. investments:

I found some proof about wire properties affecting sonics, but also found no point to spend thousands of $ per wires. By default to me they're all overovermarkettedoveroverratedoverovervalued and don't make sense therefore. One can achieve same results or better by properly researching electric properties of pro-audio wires to synergise with your system. They're priced and valued far closer to reality per performance. Why pro-audio wires, because there are more truth in description vs. home hi-fi wires. No point hiding anything or boosting parameters.

I had HHScott amp with vintage telefunken tubes and liked that one a lot, but had to sell it due to the very curious toddlers in my dwelling. I also like vintage transistors and capacitors. When I get chance to research circuit improvements and find vintage goodies I go mod my units, but most of the time I'm very busy with my vinyl/cd shop.

For powerline safety and performance I also shop at pro-audio. It's manufactured by major brands that have great support for pruduct such as Furman.

As for powercords, stock one usually has best value for performance no matter how good is aftermarket one.

I like good recepticles and good connectors and use hospital grade Marnico.

Regardless weather reviewers are biased or not, I believe that most of them hear what others sayin' or listen to what manufacturers are saying, then believe, then write something what they believe.
