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.

If you think hard enough that you won't hear something's because it seems preposterous you won't hear it. It's the reverse expectation bias in full bloom. You psyched yourself out. Lol
The paint is slightly magnetic, magnetic enough to hear when it's been demagnetized, anyway. The first ion of air molecules on the plastic CD while spinning imparts a static electric charge on the disc best removed with any number of things, anti static spray, tourmaline negative ion gun, what have you.
The CD laser is a quantum device and produces a coherent beam of light. But, since the CD laser is a *quantum well* that operates by quantum confinement, the light beam of photons is a WAVE only, not particles. And since the light wave is in the *electromagnetic* spectrum it's quite possible it's subject to magnetic fields. Also, the physical data is located extremely close to the ink on the label, which helps the case for some sort of magnetic interference, even if the magnetic field is very small. It wouldn't take much since the size of the physical data is nanoscale.
The thought occurs to me that demagnetizers like the Walker Talisman can also be used for demaging cables, especially interconnects. Can anyone think of why cables might need demaging? They also appreciate ionizing.
Uh, I'm pretty sure the primary reason you don't see too many negative reviews is that the magazine, wisely, doesn't wish to put someone out of business with a negative review, especially if it's a small company.
Take any tweak, like demagnetization, for example, or ionization, and there will always be two camps, those that think it works and those that don't. For those that listen to any tweak, like demagnetization or ionization, again there will always be two camps, those that hear it and those that don't. There are many reasons why people don't hear tweaks. I don't think we need to go into all if them here, but an obvious one is the person's hearing ability is not all that it's cracked up to be.
