In Reply to: RE: So what's the deal with CD demagnetizers? posted by pictureguy on March 24, 2016 at 14:14:00
Electrostatic charge is another issue entirely. The earnest audiophile must both demag and use some sort of anti static treatment. Better safe than sorry.
Follow Ups:
I'd personally be more concerned with ElectroStatic charge. I've measured particles on bare Si wafers and found that Electro Static air treatments make a HUGE (several orders of magnitude) difference. Charged wafers are simply particle magnets. As I'd assume a CD/DVD/BR to be. Or even an LP, for THAT matter.
This was in a class 10 room. Cleaner than ANY operating theater, but NOT sterile.
Too much is never enough
But I question electrostatic charge as being a problem, too, just like I question magnetism and demagnetizing the disc. It's not too difficult to see where the static charge on a disc arises but what is the effect, how does it hurt the sound? Static charge is a magnet for particles of opposite charge, that's true. But so what? How does it affect the sound? Certainly not by affecting the laser beam.
A clean disc is a happy disc.
I would use the Zero Stat to remove dust / reduce dust buildup.
I doubt much or ANY actual audio degradation at least until the point of obscuring the laser.
Too much is never enough
Sorry, not buying it. Never see any dust on any CD. Besides the static charge builds back up and one must resort to anti static measures once again at some point to restore the sound. Yet there is no dust inside the player, it also doesn't explains why destat improves record play since dust is not really an issue for records, is it? And it doesn't explain why removing the static charge from interconnects improves the sound.
again, assuming 'facts' not in evidence.
One of the MAIN reasons I gave up vinyl in about '84 was all those ANNOYING pops and ticks. In extremely DRY climates, I suspect it is even possible for the electrostatic charge to effect Tracking Force.
In the interest of COMPLETENESS:
(I would use the Zero Stat to remove dust / reduce dust buildup) IF i ever had such a problem.
I experimented BRIEFLY with pop / tick removal. Maybe 45 seconds. I JUST 3 weeks ago gave away a good DBX NX-40 compressor / expander which found use on a R-2-R but I NEVER succeeded in finding a DBX encoded disc.
CD is not very susceptible to such dust. DVD moreso, due to the smaller 'pitch' of the geometry and BR perhaps even MORESO. That being said, I've NEVER in 30+ years of CD ownership EVER had an issue I could ascribe to dust or such buildup. My ORIGINAL 3 discs including a wonderful Eric Clapton Blues Breakers has NEVER had a single issue. The garage sound of that that disc is wonderfully preserved and reproduced.
Too much is never enough
Well, you somehow managed to totally confuse me. On one hand you say electric static charge attracts dust then you turn around and say CDs do not attract dust. Color me confused. In any case, there is no doubt that both demagnetization of CDs and LPs and interconnects is beneficial to the sound. And so is the use of ionizers like my Particle Accelerator or anti static sprays such as my Sonic Tonic or Nordost anti static spray. It's just the operating mechanism that we are only guessing at. Don't get hung up, just keep moving, it's hard to hit a moving target.
