I think cow tipping is ahead of turtle rolling on the waiting list.turtle rollingCOOL! isn't that a new Olympic sports? it should be
Yeah, after break-dancing that should't be a problem, not to take anything away from break-dancing its-self as an art form or a way of expression, some people are very very good at it and it surely takes a lot of exercise and practice, but i just don't see it as a sports.
Looks like a very nice container for coffee beans.
They also make a $7000 version and suggest you put one in each corner of the room!

It kinda makes me think of this in a way hahaha,
and probably achieves the same
At least this one has the "proper" name attached to it.
No doubt It will improve the fidelity of the birds songs,
so they may really be on to something here!

You don't know how hard I bit my metaphorical tongue not to give a shout-out to breakdancing in my earlier post.
Then again, maybe all y'all do.

Back to the snake oil.
This is the
“An interconnect is a high impedance device,” said Kelly, “picking up anything that shouldn’t be there and its a place where you should spend money to make sure you have good screening. A speaker cable is different. It’s a low impedance device. It’s doesn’t pick up, it broadcasts. It changes frequency very rapidly with a lot of power (I’m talking about passive speakers here). I’m also talking tens of amps with fast rise times. Do that and you create wideband noise which broadcasts into the environment. It’s a bit like turntable feedback coupling back into your amplifier. Here, it comes back into your interconnects and into your amplification system as noise. It’s a feedback loop. The longer that cable, the better it is at turning into an antenna. That is fed back around into your hi-fi. If you can cut down the broadcast nature of the cable, then the RF load in your system is reduced. By connecting your screen to Ground, you can eliminate that effect.”
This comes from Atlas CEO and Chief Engineer, Kevin Kelly.
So a length of cable with supposedly solid (not stranded!!!!!) conductors is "high impedance" ????? Oh but speaker cables are "low impedance"..... errrm, they're pieces of wire too... I don't know what they're teaching at the University of Strathclyde but if an individual with a science degree in Electrical and Electronic engineering can declare pieces of cable high impedance and low impedance at the same time, they must have skipped ohms law.
This is the
Atlas Asimi Ultra Luxe RCA Interconnect.
Yes, it's got a stitched leather sheath. You can actually choose from a range of materials and stitching here but that's what you'd expect if you were paying around five grand US for the metre long version. Now I hear you, "just another overpriced "magic" cable for the hi-fi jewelry enthusiast" and I agree but what I think is worth revealing is that the designer of this has the following to say.“An interconnect is a high impedance device,” said Kelly, “picking up anything that shouldn’t be there and its a place where you should spend money to make sure you have good screening.

I can only imagine he's talking about the assumed input impedance of the devices that the cables connect to. It's just weird that he doesn't simply say that.
This seems like classic example of: "What what? People are really this ignorant?! And I have no conscience. It's a perfect match! I'm gonna be rich!!"

Such a pile of BS. Speaker cables nearly don’t radiate at all, due to the fact that the positive and negative lead cancel each other out in their electromagnetic field.
Interconnects will usually be driven from a relatively LOW impedance source, roughly 100 ohm or there about. By no means a high impedance device. By the way, one should not mixup output impedance against input impedance.
Then all of a sudden he mentions ‘RF’, where does that come from? RF is a completely different spectrum. The audio wavelength is so large, you’ll never realize 1/4 wavelength antenna radiation requirements with your audio cables. To give you an idea, a 1 meter (3 feet) unshielded cable is starting to act as an antenna, receiving and transmitting, for frequencies of 75 MHz and above. This is way outside the audio bandwidth and due to CE regulations proper audio equipment should not be susceptible to this.
Screen = cable shield.

Agree. Having worked in RF for awhile, all I can say is that at 20kHz, I get out and walk. It' a big nothingburger.
