ERS Paper - picture and video thread - Page 3

post #31 of 376
I like the new ERS paper video.

I'm surprised you listen to 128kbps MP3s with such an expensive rig though. You're spending a ton of money to eliminate RFI, then using quite lossy source material.

Didn't you know that insulating your whole rig with ERS paper increases the audio quality of 128kbps mp3 to 2048kbps?

Actually, its 2,000,000 x 128kbps, which is beyond my calculators ability to display.

BTW, why are we whispering in the video? The television (or whatever) in the background is louder than patricks voice? What gives?

I like the whispering. It gives the videos a mad scientist flavor.

According to one of the RFI resonance druids at Audio Asylum, power cables create nodes everywhere there is a connection/impedance mismatch. (plug, socket, IEC etc) RFI is picked up by these nodes and standing waves with wavelength multiples of the node length resonate in the node. These RFI resonances are strongly reinforced at that wavelength and affect circuitry particularly digital.

Shielded powercords help avoid this, but if the cords are not shielded then the recommended trick to avoid most tof the problem is to wrap a 3 inch wide strip of ERS half way along the cord, and at 1/4 and 3/4 points. These are the points corresponding to the crossover of the standing wave at the fundamental and first harmonic where the ERS will stop thewaveform reinforcing, and eliminate the mmajority of RFI resonance.

So its not really needed on shielded power cables, nor all along the cord for the majority of RFI resonance.

The same principle works for unshielded analog interconnects and speaker cable, however care must be used when using on analog cables as the ERS can actually negatively affect proper analog transmission of the signal and do more bad than good, depending on the severity of RFI.

I have found ERS has an effect for me but it is subtle and I limit it to the inside chassis of DACS /CDP/DVD players.

I'm not whispering, that is my normal voice. I don't have enough testosterone to make stronger voice.

Gentlemen, we can rebuild him. We have the technology. We have the capability to build the world's first Valhalla man.

Make the skin out of ers material. Maybe turn all that thermal energy inside the body into electrical, then filter it via noise harvestors, regenerated, and finally turned back to heat..For a more noiseless warmth! Maybe some shimmering pebbles dispersed throughout the body would absorb excess movements. The legs would just be the pneumatic section from his rack/table. Then just fill the cavity in the head with some liquid testosterone. Imagine an oversized womanizing r2-d2.

24 days without anything burning up, I'm lucky. Even if system goes up in flames after making this post it doesn't matter because the sound is already burned into my long-term memory, amazing paper.

Placebo still hasn't worn off, I guess it's real then. The biggest improvement ever, for any price! I'm hearing new worlds of detail and they don't seem to come from inside my head. It's great.

I'm planning to buy more paper so I can cover my computer too, it is water cooled so no problem with heat.

Great savings on the power bill then...

It sounds like the TEMPEST shielding the military uses. I doubt there are many civilian applications, which is probably why it's so expensive. That, and it's an "audiophile" product. Look at how expensive even fuses can be when they turn into audiophile products!
At least you get gold plated fuses with silverthread inside.

Yup doesn't need the expensive nordost thor powerconditioner anymore.

He can buy loads of ers paper for that kind of money.

I am interested as well, might put it in my amp and cdplayer.

I think it's 20 bucks a piece, right?

Patrick, does it help shielding the powercable? As you can read in a thread i opened, i removed the shielding of the powercable and got lots of improvement.

I can see how shielding on a cable can negatively impact its sound.

If you want to learn something new (which might help explain some audio phenomena), check out this page: http://amasci.com/elect/poynt/poynt.html (and the rest of the site is good to learn too)

Basically, it says that electrical energy is carried in EM fields in the insulators outside the conductor, and not in the conductor itself (it just serves to guide the fields). Crazy stuff. And no, this isn't made up theory, it's physics.

OMG... the most extreme videos I've ever seen. As long as you notice the difference and can afford to pay for it, it's all worth it. Congrats and keep up the good work

Yes, 20 bucks a piece. But I wouldn't only buy one to test it. If I did I wouldn't have believed it made a difference. It all adds up which makes it easier to hear.

Electronics students commonly assume that electrical energy flows inside metal wires. Physics students know differently! Normally the electrical energy doesn't flow inside of metals. In fact, the electrical energy being sent out by batteries and generators is located in empty space: it takes the form of electromagnetic fields surrounding the wires.
Yes, that's why dielectric makes a difference. For some reason electrical engineers want to ignore that.

Putting the conductors and shield further away gives better sound. That's what Tara Labs does with their cables. I have modded the Valhalla to get the same results. I have space in between all conductors.
The shield is also like a conductor with an electromagnetic field around it, so you need to separate it from the conductors also. That's why cables that have shielding wrapped tight around them sound muddy. You need to put the shield further away. I tried it and it works.
