Mapman is most likely just on a leisurely troll. Just a guess. |
The ex demo ICs are definitely something to contemplate. Would love to have them for my humble headphone system. |
vibration isolation is simply the attentuation of structural vibration, including that produced by Earth crust motion, wind, traffic, subways, etc. If it were as easy as coupling then everyone would throw away their 10K dollar isolation stands and the search for gravity waves would be concluded at last. It's the stuff with frequencies below 5 Hz that can have the highest energy and be the most difficult to ameliorate. |
The Coulomb Effect is well understood. Coupling is well understood. The Diode Effect for cones is well understood. And vibration isolation from very low frequencies is well understood. But these techniques are not interchangeable. They are complementary. |
A question: for isolating a scanning electron microscope, which would be better for purposes of preventing movement of a specimen while it's being photographed -- a coulomb effect device or mass-on-spring device? Answer at 11. |
That's weird. I found lead to be one of the most harmful materials, evicerating the bass frequencies and generally just making the sound, uh, sound funky. |
One of the most important things I've run across recently is the value of damping or isolating the toroidal transformer from the printed circuit boards and to isolate the printed circuit boards as much as possible from the rest of the chassis. Damping the capacitors is also a worthwhile endeavor. Constrained layer damping for CD transports, transformers, top plate of isolation stands, etc. has proven to be Verrry Interesting. |
Just for the record, and not being a fan of soft materials as a general rule, viscoelastic damping material is a "soft" material. The viscoelastic material just needs to be constrained, allowng vertical vibrations to be converted to heat via horizontal motion of the viscoelastic layer. |
Over thirty tube traps in a small room? Now I don't feel so bad about having so many Shun Mook Mpingo discs. :-) |
I'm not about measurements either, you know, just in case you got that impression. |
What do you think the magnets would have an effect on? The audio signal? The dielectric? The jacket? Just curious...... |
That's one angry audiophile. |
Helping a human being out? Do tell. |

"It's a safe bet that there is a concrete relationship between magnetism and electricity. Any electromagnet is proof that the relationship exists. How to apply it in reverse exactly in teh interest of "better sound quality" is beyond me, but its a topic that I am willing to learn more about."
Current in a wire produces a magnetic field. You remember the right hand rule. Does a magnetic field interfere with or influence an audio signal? Does an audio signal have mass? If the audio signal could be influenced by magnets it should have mass, right? |
Badman wrote,
"Using magnets around audio is not a new idea, it's been tried every which way. The primary way it would apply to cables, is to make them worse, not better, if having an influence in the audio band."
How can magnets have an effect on the audio signal since the audio signal has no mass? |

"Enjoy the music." If I'm not mistaken that's exactly what the bandleader told the people gathered on the Titanic's deck while the ship was about to roll over and plunge to the bottom of the sea as the band prepared to strike up a rousing chorus of Don't let the Sun Catch you Crying. |
If the alloy in HF cables is like mu metal it's conductivity is around a fourth of that of copper. I'll take the copper, thank you very much. |
Sabai wrote,
"Because the physical carrier of the signal has mass."
The carrier is either copper or silver and usually of high purity, therefore not magnetize-able. Nice try. |
You can't tell the Poindexters without a score card. |
Tom wrote,
"If you took the time to read Ricks patents you would learn that he describes the use of an alloy that is ferro magnetic as a key conductive ingredient not the 2 materials you mentioned. The CT-1 conductor is made from highly permeable alloy that, once attached to the connectors, becomes fully magnetized."
Very good, Tom. So I'll ask the question again: How can a magnet or magnetic field influence the audio signal if the audio signal has no mass? |
if magnetic fields were good for the sound then the copper or silvers wires would do just fine, you know, what with the induced magnetic field arond the conductor that results from current flowing through the conductor. Besides, wouldn't the mu metal *absorb* the magnetic field? I mean, i'm pretty sure that's kinda what mu metal does. Hel-loo! |
The magnets are affecting what, the signal or the electrons? Just curious. |
"Also, when they annihilate they produce a pair of 511 Kev photons that travel 180 degrees from each other. Probably not what you want happening in your listening room! ;-)"
Only if it improves the sound. |
Magnets attract or repel electrons but unfortunately not the audio signal since the signal is not electrons. Follow? |
If magnets would make electrons move faster than one meter per hour I'd be a happy camper. Get along little electrons, get along! |
Oh, one more thing. Wouldn't the electrons clump up into a big ball around the positive end of the magnets? Am I missing something? |
Doesn't that beg the question: If mu metal is used for the conductor, presumably to avoid the consequences (magnetism) of current flowing through wire why are magnets used for the conduction, magnets that ...drum roll...produce magnetism? See the irony? |
Another question for the manufacturer to answer. Why use mu metal or an similar alloy for the conductor when copper is an order of magnitude better as an electrical conductor? Order of magnitude - that's 10 times better for you English majors out there. |

"Its all relative I suppose. I'll be sticking with my modest DNM ICs and Pangea power cords for the foreseeable future though because, well, as much as I like good sound, I am still basically a cheap skate on the grand scale of things."
You could have knocked me over with a feather. Lol just kidding, no harm, no foul. |

Mapman, one assumes you're referring to Judge Judy. |
Mapman, even better, they are both Rick Schultz. That would be way cool!! |
Theaudiotweak, Of course it's only fair to point out that magnetic field has nothing at all to do with mechanical isolation, so I suppose one could say that was a Strawman argument. Good one! |
The audiotweak wrote,
"How do you isolate these cables from the Earth's magnetic field."
Why worry about that since the Earth's magnetic field is very very low compared to say the magnetic field produced by say transformers and even conventional cables. Not to mention that the high permeability mu metal conductor in HFC is an absorber of magnetic field. Hel-loo! |

"Damped if you do and damped if you don't. Damped is your key word and definition by all examples."
Hey, Tom, what in Tarnation are you going on about? Are we still talking about isolation? Help! |
I've been jamming all day too. On my cheap portable cassette player. Tape is a natural medium. It breathes. Look ma, no speaker cables, interconnects, digital cable, or power cords. Are no cables at all better than high end cables? |
Careful, Mapman's head is in danger of exploding. |
Ah, there it is! The old moralizing. It was bound to happen sooner or later. Lol |
Well, just to be fair, it's not actually a "populist" viewpoint. It's a pseudo skeptic's viewpoint. |
I was not offended. If someone spends thirty or forty years and how many thousands of dollars, what, maybe $100,000, who knows? trying to improve his system, buying any number of complete systems, and find audio nirvana I'm pretty sure he should probably just admit that at least one time in his life, including perhaps recently - oh, no! Say it's isn't so - his system didn't sound all that great. It's OK to admit it. It'll make you feel better. |
"My system always sounded good..." Really? You mean it never sounded bad? I hate to be skeptical but I find that difficult to believe, you know, since audiophiles by and large are driven to extremes by the rather poor sound of their systems, at least initially. It's ok to admit you used to have bad sound, you know. |
Your hearing is only as good as the best system you've ever heard. Old audiophile expression. |
Four treatments for discs? That's very interesting as I'm big into CD tweaks. Share, share! |
Ddraudt - thanks for comments. I've been using tweaks on CD since Christ was a Lieutenant. Among the ones currently in use are Essence of Music (surprise! Lol), Super Intelligent chip, Walker Talisman degausser, Dark Matter invisible infrared light absorber (recall most of the scattered laser light is in the infrared region), Cream Electret from the Belts, my Particle Accelerator Tourmaline Gun ionizer for CDs and cables and last but not least CD coloring kit that uses turquoise green for outer edge, black for inner edge only (black usually degrades the sound used anywhere else) and Multi Colored dots of color on the data side near the spindle hole. |
Tbg, that's weird. I have a friend in CA who reports good results, no, the necessity of treating CDs prior to ripping. He also has the edge beveler, colors the CD, Marigo mat, along with a lot of other things as well as tweaks the bejeezus out of the ripper and the Hard Drive. This is looking like it might be a controversial subject. Lol |
I am out there and loving it. No power cords to worry about. No speaker cables to worry about. No interconnects to worry about. No transformers to worry about. What, me worry? |

"Geoffkait, if you know that current flowing induces a magnetic field, why were you asking about how magnets can affect something without mass?"
I mentioned the fact that current induces a magnetic field just to show that there is already a magnetic field where the signal in running through the wire, that there is no reason for the special alloy to introduce a magnetic field, which is what one poster surmised. I asked how magnets can affect something without mass like an audio signal because unless the signal is affected by the magnets what's the point of the magnets?
Tbg also wrote,
"Ever run a magnet along a cable attached to your speakers?"
Yes, I have. What do you think the magnet is doing in that particular case?
Tbg also wrote,
"What I don't understand is how a constant magnetic field from the magnets can affect noise from EMI or RFI, especially without also affecting the audio signal."
Actually I don't think your statement is true Re the magnetic field and RFI/EMI. I think that's a separate issue. Mu metal is for (absorbing) magnetic fields, you know, what with the permeability but you need AB5100S or some other way to deal with RFI/EMI which is very high frequency electromagnetic waves, as opposed to magnetic fields. Follow? |
"Swampwalker, just a quick point about positrons that I mentioned in my previous post. Although they do exist, they are only produced during very specific radioactive decay processes. They are not in natural abundance and would likely not be involved in the effect described."
More to the point positrons and electrons are self annihilating.
