PS Audio Noise Harvester

What do you think of this audiophile coat? It has 4% carbon fiber inside. http://www.esd.tv/Clothes.html

Should I get blue or white? If I get white I can take it with me when I get commited to mental institution. But with the white coat the stains are more visible, I would like blue for that reason. But I don't want to buy another coat when I get commited.

QED, the material is for ESD protection, not EMI.

ES, I think you should get a nice wind-jacket and spend more time out-doors.

I call you now for pulling our collective legs :p , and you did quite well. Congratulations! :)

The more noise the Harvester removes the more noise is radiated out of the wire before reaching it. That's why I heard a difference when the wire had better shielding.

In other words, according to your logic, the harvesters worsened your noise problems, but you mitigated that by using a screened cable :roll:.

Most of the noise comes from the power conditioner plugged into the same AC outlet. You can see how much they blink in the video.

Then the solution is obvious: Scrap the power conditioner, the harvesters, and the screened cable.

While you are at it, remove all that ERS paper before it catches fire, tidy up and clean your room, then invite a girl.

Hey, I use an MP3 player to listen in the gym, and bought some good earphones to make it sound better. I find it hard to tell high bitrate MP3s from lossless files in a blind test at home, and no way I'd be able to do this in the gym - so why worry about an audible deterioration of sound I can't hear.

Admitedly, my earphones are small, not shiny, and don't include toilet paper. Still, I'd argue that good quality MP3s can sound pretty good; I'd guess (though couldn't back up with measurements) that any deterioration in sound caused by compression will be less than that caused by speakers, room interactions, etc in most settings.

But that's not what I'm talking about. There is a world of difference between someone listening to music on an MP3 player because they enjoy it and someone spending thousands of pounds on expensive equipment to get the "perfect" sound. At the gym, the quality of the sound, as you say, is pretty much irrelevant. As long as you can hear the music you can enjoy it. In the latter case however, the differences between MP3s and lossless and between headphones and speakers are orders of magnitude greater than any little changes in your wiring. Anyone listening like this cannot possibly be interested in sound quality to this extent, only in the gadgetry involved.
 
My father is a tweaker of things that he makes, drives me up the wall, just never ever happy with anything, he just can't enjoy something for what it just is, years, no decades go by and the projects he started are still not done.

This kid just whats to play games with his toys.

I don't want to play games with toys, I just want to listen to proper audio that doesn't sound broken. I don't enjoy tweaking 16 hours straight with back burning from pain from bending over so long. When I got my 2nd batch of ERS Paper it took a couple of weeks for my back to recover from the injury. I couldn't bend over anymore.

Wrapping my system in ERS Paper makes it sound less broken. If it didn't make a difference I would remove it. One time I removed it from my P300 Power Plant and wondered what happened to the bass, I checked my whole system and didn't know why. After I wrapped my P300 with ERS Paper again the bass was better than ever before. The plate of P300 is open a few inches for better airflow, it is in the path of radio broadcast towers outside my window.
 
It's really bad where I live, it's an old house with crappy wiring and vibrating floor. Radio towers outside my window makes it even worse.

My first amp picked up radio channels, I could listen to radio through my headphones. When I replaced the cable the problem was reduced but wasn't gone. I had to buy another cable and that solved the problem, I didn't hear radio anymore.

The components themselves dump noise back into the AC outlet which interferes with the other components. Just scrap all the gear...no music but problem is solved...:rolleyes:

I don't do humans. I want something with a clear outer skin so I can look inside. Each of the intestines need to be in air dielectric. The intestines also need to be silver plated and highly polished. I will dress it up with ERS Paper clothing.

No you play with your toys, you have no true theory behind what you do, I am saying it like it is, and no the paper does nothing, it is all in your head, you know what you have done with the paper and you hear what you want to hear, you are no (none) different then all the other so-called audiophiles who think they heard things that with their so-called golden ears that no one else does, and in ever double blind test they fall on there faces. And what you are doing is BS my friend, I have been in the hobby for over 40 years now and I have seen the BS come and go. It is all the same BS, just in a different package. Also if you hear it that will there is that million dollars U.S. just waiting for you................ Randi is waiting………. Call………….

Now that's interesting and may explain some of what you are hearing. I once lived close to multiple 50kw erp FM transmitters. The emi level interferred with all sorts of items. I could actually capture a significant signal on a 6 inch gnd clip loop of a scope probe in mid-air.

Perhaps you should build a Faraday cage into your room.

Attack and decay? I don't even know what they mean by that, in the context of equipment. A room has attack and decay parmeters, it is an acoustic thing. The reproduction equipment should not play a role in it.

As for the audiophile contra engineer thing, I have seen the same in other belief systems. Our old Kumar was a prime example: He thinks that as long as science does not know everything, then anything is possible.

What they fail to realize is that there is negative knowledge and positive knowledge. If I say: "No external noise can change the frequency characteristics of an amplifier", I'm in the deep end. And obviously, I can't prove it, since you can't prove a negative. However, if I make statements about how EM signals are radiated and propagate, I'm on solid ground, provided I'm an expert in the area (which I happen to be).

Just an OT sidenote: A negative is not necessarily impossible to proof.

It is a stetment of the form "there is no a with property b", which can be falsified easily by showing one a with property b.
OTOH if the number of a's is known and finite and all a's are accessible then the opposite can also be verified (in that case you can show all a's).
Another possibility is an indirect proof - assume there is an a with property b and proof, that this would be a contradiction in itself.

Besides that, maybe we skeptics as well as the audiophiles may be barking at the wrong tree. As a semiprofessional violinist I am used to noticeable differences in the sound of my instrument if there are changes in the properties of the room where I am playing. Just opening or closing the curtains makes quite a difference, even in the response of the instrument which, as an acoustical device, interacts with the acoustic of the room. (in a room with a resonant frequency near g sharp my violin has a terrible wolf note on g sharp played on the g-string makng ths note virtually unplayable) Changing cables, wrapping the amp, slight changes in position and direction of the speakers will slightly change the acoustic properties of the room as well as cause phase shifts in the sound reaching the listener and make an audible difference to people who are trained to listen to such differences. Sounds incredible, but if you consider, that the trained ear of a violinist (not mine to such an extend) can hear a difference in pitch of much less than 1/10 percent, it could be possible for some person to hear very small differences in room acoustics as well and erroneously blame the equipment when the cause is just, that they are sitting 10 inches nearer to the speakers.

just my $0.02
 
The time of day has a lot to do with how you perceive sound too, there is a reason that concerts are not done in the morning but usually in the evening.

Yes. That's the second possible cause. And there may be more to it, but most of it not related to the equipment, but to the listener. (woo included)

Btw, I'd prefer to play concerts in the morning: pull me out of bed, kick me on stage (I am dying the whole day of a concert from stage fear :))
 
I am not a morning person, the only thing that the morning is for is to get the the rest of the day..................

Why, if it is something you love to do, you should be passionately crazy to do it any time of the day to drive the audience out of their minds, I know I would.
