didn't mean to put you on the spot,. My apologies if I came across that way.
A while back when the Bedini Clarifier came out and such there was a discussion about the effects of demagnetizing a CD (actually, there seems to be a minor controversy about it). One postulate was that it simply was eliminating static as an explanation for the sonic effects. Using the Zero stat and comparing the sound of a demagnetizer ( a tape degausser works just fine, BTW) was interesting and since we're this far along, produces a different sonic presentation.
As for static itself, I've often wondered about it myself. Since digital signals are simple pulse codes, could a static discharge be perceived as a change in the data stream? In a conversation I once had with an analog to digital engineer, he mentioned that for his medical work, true 20 bit resolution was very difficult to achieve because of 1/f noise, at least nt to the point where his medical gear could guaranty 100% accuracy. This was about 4 to five years ago and perhaps things have changed, but he definitely fingered random power supply noise as one culprit.
I do use the demagnetizer frequently and often, BTW, even for my LP's, and I notice now that Furutech has an LP demagnetizer... That I figure should be right up your alley, expertise wise. Then again it's one more aspect to puzzle about in audio and human sensitivity.

Hi Stu,
Not offended at all. I was just trying to verify that you meant using it to zap the disks rather than to sniff ionized air.
I imagine there are several possible ways that a spinning charge can affect CD players. It may simply be picked up by the circuitry or do something like physically attract the focusing lens assembly causing additional modulation of the focus coil current.
All that is easier to imagine than what magnetic effects there can be with a vinyl disk. I don't know of a mechanism. A CD on the other hand at least has the metalized layer that one can probably induce eddy currents in which could conceivably have some effect.
It's always bothered me that the CD metalization is typically so thin. I can see the label printing from the business side of the disk if I hold them up to the light. Well if I can see it, surely the pickup can also and it must introduce at least a small error term in the signal. And yes, being digital with ECC it shouldn't overtly not come through, but we all know that some if it may sneak in the back door.
1/F noise is both part of the universe and a statistical surprise. The big bang still echoes, luck really does run in streaks, semiconductor crystals have defects and we don't live forever. But digital is at least overtly free of it. Actually it's not but we force it out of band by keeping stuff powered when in use. I sure don't miss rumble.
I bet you'll enjoy the stone folks, fanatics are fun. Other than picking up souvenirs I've never been one, but used to go their annual shindig in Sweet Home just for an outing.

Problems with these theories arise when one begins using the zapper on cables and *non-audio* related items in the room or adjacent rooms, -- e.g., clothes in the closet(!).... I implore you, why would that improve the sound? :-)
GK
Well: you'll have to be more specific...
Plus I don't know of what theories you are refering to, as I didn't postulate anything on zapping cables or non audio components. Don't quite see a connection to crystal rocket fuel either, so you'll have to pardon my ignorance.

Stu
I know you didn't. Now, I suppose you're going to tell me you've never tried zapping cables or non-audio items. For shame!Who said there's any (direct) connection to a crystal fuel rocket engine?
Cheerio, GK
that smacks of utilizing a scientific principle of reduction of static charges! I simply changed the decor to all red and use red jacketed cables exclusively, in odd numbers, of course.

Stu
Mr. Smarty Pants, please be so good as to tell me how reducing static charge in another room can affect the sound. What is the scientific principle?
Cheerio!
now you're adding more qualifications, but nevertheless, since static electricity is involved as your comments seem to indicate, and that static electricity is an occurrence rooted in 'science', quite obviously there can not be any acceptable 'scientific' explanation.
It would be like attributing a causation to explain why I get zapped at Vegas when shuffling through the casinos' carpeting and touching the brass fixtures. There can be no other explanation other than a 'mysterious' field pervading the universe. After all, I can get zapped in the elevator, in the lobby, and even in other hotels!

Ah, c'mon GK, lighten up, didn't you see the smiley face? I'm just pulling your leg.....
Stu
I couldn't resist
