PS Audio Noise Harvester

Coloration can also be caused by harmonic distortion. ES referred to this in his comment about certain audiophiles who prefer vacuum tube equipment.

Another factor is damping ratio. Here's a relatively good article describing what it is and how speakers and amplifiers work together (or fight each other):

http://www.classic-audio.com/marantz/mdampingfactor.html

I suppose damping factor is another way to affect the balance between harmonics, but it is better to just talk about damping factor on its own. Some speakers are more sensitive to damping factor than others, so certain amplifier designs have an adjustable damping factor that allows the user to adjust the amp to the speaker. Here's an example of one such design:

http://www.supratek.biz/poweramp.htm

I read through the page and while most people will think the Suprateks are pure b.s., the technical basis for their claims are sound. Of course, I have no personal experience with these amps but these ideas are nothing new in the field of tube amp design. Audio Cyclopedia has a rather interesting section on amplifier output impedance and its effect on different speaker loads, and electrostatic speakers seem to be the most difficult load for an amplifier to handle.

Anyway, I thought I'd bring up damping ratio as an example of something that isn't so much an influence the steady-state frequency response as it is on the transient respose of the amp.

Edited to add:

I forgot to say that like harmonic distortion, damping ratio can also be measured, no magic at all.

Well, there might be a definition think here, but in my book, those things are not coloration, they are various kinds of distortion. OK, damping can affect the frequency response, but otherwise, I define coloration as the ratio of reproduction between various parts that exist in the original signal. In contrast, all kinds of distortion add components that were not in the original signal.

But, it seems our extreme friend has taken absence. Here's to hoping he actually took the advice from several of us and went out to get himself a piece of life.

I will say with 100% certainty that it has no merit. Power line noise doesn't affect a modern, digital amplifier. And you can't "harvest" noise, you can only filter it out. Even in a crude analog tube amp, where power line noise might cause a problem, you'll have a small filter on the line (a simple choke coil) that will eliminated.

This is 100% pure unadulterated moose cakes, and will affect your audio every bit as much.

This makes you 100% the fool and though its many years later I'm certain nothing has changed for you.

So is this board full of armchair opinions based on self conceit of knowledge?
Or does anyone have the balls to go out and try stuff and make their opinion based on experience?

Since most folks don't invest in high quality sound equipment no point in wasting effort there.

But most folks are investing in HDTV these days. Get one of these (it’s returnable) and plug it into the same wall socket you HDTV is plugged into and let your eyeballs be judge.

My experience: much greater picture clarity leading to better colors and picture depth. Much more "pop" to the picture.

In audio, plugged in next to my amp much quieter and expanded soundstage, more definition and palpability to instruments especially bells, cymbals etc.

I'm an electrical engineer and he was right.

There is a word for this.............. BS.


A great Video for all you other guys,

Listen to JJ that the beginning sudhn, I hope you learn something.

Tweaking is fun, but there's decreasing audible difference as we go down the list:

1) speakers
2) room acoustics
3) room noise, or quiet
4) speaker placement (all of these top four are nearly equal)
5) correct wiring and setting of controls
6) your brain, ears and mind-set (for example, is your hearing dulled from being in a noisy city environment or a loud crowd for several hours?)

7) adequate pre-amp or mixer
8) adequate d/a converter
9) adequate amp

etc.



After the 9th item on the list is accounted for, there's not much effect.

People might argue about the ranking of some of these items, but not whether they make a difference.

That last bit about expanded sound-stage, etc. --if you can tell the difference in a blind test, let us know.

Becareful of accisont others of being fools, lets you look like on yourself.

No several of us are engineers.

Or does anyone have the balls to go out and try stuff and make their opinion based on experience?

Do you have the balls to conduct a blind test?

Since most folks don't invest in high quality sound equipment no point in wasting effort there.

Depends on what you mean by high quality.

But most folks are investing in HDTV these days. Get one of these (it’s returnable) and plug it into the same wall socket you HDTV is plugged into and let your eyeballs be judge.

Have one. Yes, higher resolution makes for a better picture. Surprise, surprise.

That is sort of the idea, yes. And we know how it's made; no magic here.

Of course, this comparison to HD TV probably highlights a very basic issue: For people without any technical insight, it is all indistinguishable from magic.

So if you have no idea about how HD TV is created, it appears comparable to the noise harvester.

The annoying thing, however, is that these people refuse to listen to what engineers say.

You just insulted someone on a science forum for speaking from scientific knowledge and then gave us your vague subjective experience as if it trumps the science.

You’re the one coming off looking like a fool here, trust me on that one.

Honestly… “pop”? “Palpability”? What the heck are you smoking?!

A collective response to all the "engineers"....

This is not a science forum. Science asks questions and doesn't rest on what is thought is already known.

This is a "here's what I have memorized and been told and am so sure its true" mediocre "engineering" forum.

I quite realize that most "engineers" (95%+) are basically the sum of equations and circuits you have memorized from your texts.

As you have all forgotten (or likely never learned) most new territory in science always begins with observation and objective analysis of the observed (heard or seen) phenomenon. Science realizes that while everything is quantifiable (yes, there is no magic) we do not know yet how to measure everything (and lets not even get into the fact that the act of measuring can be flawed in ways we never expect and can affect the results).

So I ask again, have any of you actually tried the device and done some objective observational analysis????

But you can’t make an objective analysis of what you hear or see? I feel bad for you.

As for the one post who says something along the lines of "one post and out of here", I am among fools who don't know the difference. Yes I won't be hear long so you can all return to regurgitating what you’ve memorized and are so certain is true.

Yes, and as things become increasingly complex the percentage of the population that will easily recognize this sort of nonsense shrinks. Sigh.

I feel so very sorry for you;

Have you done a blinded test? If not, are you really sure you aren't just hearing/seeing what you expect to see?

Scientists ask good questions, otherwise they waste their time and fail. Whether your product works is not a good question, because the answer is already known: no.

If you believe otherwise, do a double-blind test and prove it. Anything else and you'll be laughed at.

We do know what BS, Woo-woo and snake-oil are. The Noise Harvester does not science behind it. If you think it does, show the science.
