Breaking News! I installed 30 copper bowls, 15 were 1" and the other 15 were 1/2". They were all installed in room corners, upper and lower, in some cases more than one per corner as there are 3 surfaces per corner. Without commenting on the sonic results yet, in my portable headphone system, I'm reporting that the TV picture is quite a bit better. In fact I had to recalibrate the color saturation from 3 down to 2. Never had to do that before. Whaaaaaaat? 😀
Cheers, everybody!

Geoff, I waffle between thinking you know what you're talking about and thinking you're a loony.
I bet you'd be fun to have a beer with. Non magnetic, of course
What's this, Revenge of the Nerds Pt. 2?

sabai OP
geoffkait,
I see. Your comment that seemed very clear needed some explaining.
Sabai, actually I haven’t explained anything yet. Aren't you even curious?

"Geoffkait often waffles as you correctly observed. He owns an audio company so his postings should be read advisedly. His agenda is obviously to promote sales. Otherwise, why would he mention his own products and history so frequently? Not for educational purposes. All in my opinion."
Huh? What you interpret as waffling is actually your misunderstanding of what I said or your jumping to conclusions. You have done this many times on this thread, I’m afraid. Your continued snarkiness is duly noted.Â
have a nice day

Jeffrey,
To close the loop more or less, my use of magnets, colored magnets, has nothing at all to do with RF, EMI, electromagnetic fields, with addressing magnetism is the audio system, or with the audio signal at all, actually, or with room acoustics, or even house wiring for that matter. And the products of mine that incorporate magnets, with one exception, do not address any of those issues either. I know what you’re thinking, what’s left, right? That’s what I meant when I said this talk about magnets might open up a whole can of worms. 😃

Geoffkait: "My thesis, which was selected to be presented at the national AIAA conference, was on the dodgy subject of bombarding highly magnetized metal with high energy ions to produce low thrust for an engine to be used for interplanetary travel."
Is that how you plan to make it back home?
Whoa! What?! Ouch!

Jeffery75 geoffkait,
I have attempted to educate myself concerning magnets and colors, are you referring to different alloys as color? That is the crux of my post and what I misread into as being sarcasm.
i already explained that too. They're painted magnets. Either neodymium or ceramic. I also already explained different colors for different materials. Going a bit further, blue for anything steel, red for anything aluminum, green for any glass including mirrors, TV screen, any and all colors for wood.

geooffkait,
This is from Wikipedia;
A magnetic cartridge (phono cartridge) is a type of transducer used in the playback of analog sound recordings called records on a record player, now commonly called a turntable because of its most prominent component but formally known as a phonograph in the US and a gramophone in the UK.
This from Dynavector;
The The DV XX-2 MKII retains the benefit of the flux damper but features the Alinco-5 magnet and the similar rigid construction to the Te Kaitora Rua. Alnico magnets exhibit high magnetic flux density combining with a low coercive therefore magnetic resistance is lower than other magnetic types such as rare earth and ferrite, providing the exceptional stability of the XX-2 MKII output voltage.
My point being magnetism or it’s field wields beneficial use in phono cartridges and interconnects to stabilize signal.
Your sarcasm concerning colors of magnets really rubbed me the wrong way. Magnets and magnetism have a defining place in audio your thesis does not...
..............................
You started out on the wrong foot by misspelling my name. You also probably need to read up a little bit on moving magnets and moving magnetic fields before rushing into this discussion. I never said ALL magnets were bad or that all magnetism is bad. You probably didn’t notice my saying I’ve been using magnets in my system for almost 20 years. (Yup, you guessed it, sarcasm)
Magnetism is High Fidelity magnetic conduction interconnects is apparently a good thing. However magnetism in conventional cables is not a good thing. Due to the induced magnetic field. Didn’t I already say that? (Sarcasm)
I wasn’t being sarcastic when I referred to colors and magnets. I suppose this is the star of the can of worms opening up. (Now I’m being sarcastic again)

Sabai, I already explained what I meant by that statement.

"geoffkait,
You stated, "In fact magnetism, generally speaking, is very bad for the sound." Not in my system. There are many people who use magnetic cables and find them superior to non-magnetic cables.
Please note that my earlier posting did not refer to using magnets with cables, although I do use that application, as well."
The magnetic induction cables avoid the induced magnetic field produced by conventional cables and use high permeability alloy for the conductor which would absorb any magnetic field that might exist anyway. So, that’s not a very good example to use to dispute by statement. 😄
I never said you did refer to using magnets with cables. Nor did I say magnets didn’t work in your system. I was making a general statement about magnetism. The magnet’s magnetic field B is orthogonal to the signal direction in cables so probably won’t interfere, depends how you’re using them. Generally speaking I have no problem whatsoever using magnets almost anywhere, especially when they are painted the right color for the application. Color is just as important as the magnet. I used or have used magnets for more than 15 years, both ceramic and neodymium types, for everything from wood bookshelves to glass to circuit boards to steel or aluminum chassis, to walls and ceilings. See, I told you it would open up a can of worms. |
In fact magnetism, generally speaking, is very bad for the sound. Having electron tubes in proximity to large transformers is not good for the sound. Having any electronic elements or wiring in proximity to large transformers is bad for the sound. Even the induced magnetic field in is bad for the sound. In fact, the whole point of SHIELDING transformers is to REDUCE magnetic fields around ANYTHING carringly the audio signal and in some cases the chassis. My thesis, which was selected to be presented at the national AIAA conference, was on the dodgy subject of bombarding highly magnetized metal with high energy ions to produce low thrust for an engine to be used for interplanetary travel.

I did not fall off the turnip truck yesterday. I have been using magnets for audio applications for almost 20 years. I have at least four products that incorporate magnets in their design, one of those products is what, ten years old. Magnets actually don’t have to be very powerful to have a powerful effect. Ceramic magnets are OK. It’s all about the colors and where they go. Everything you know about magnets and audio is wrong. 😄 Magnets are one of things that signal something lying underneath, something big. Perhaps a big can of worms! 😬 |
Wouldn’t the magnets on cables attract the electrons flowing through the cable, producing a big old clump of electrons?

Oh, wait, no, it's absurd and I don't do any of that. I get confused sometimes."
Uh, oh. I'm getting a bad feeling again.

I use magnets, too. Lots of magnets. Colored magnets. Magnets on wood. Magnets on glass. Magnets on mirrors. Magnets on steel. Magnets on aluminum. Different colors for different materials. Yeah, baby! |
