| IM Distortion, Speakers and the Death of Science The point is to measure some quantifiable objective - before and after. As for equipment, I would need:1. A really good analog oscilloscope that can measure jitter in time domain.2. A really good phase noise analyzer to measure in frequency domain... | |
| 10 Audio Cable Myths and Facts I can't decide whether prof trying to be funny or just trying to be serious. Something initially may be cute, but after awhile it does get tiresome.Why would anyone gone through all the trouble trying to prove zip cord is just as good? I once wa... | |
| IM Distortion, Speakers and the Death of Science doesn’t occur in any meaningful way and hence cannot be measured. Actually, when it comes to speaker drivers (such as woofer, tweeter ....), it has been shown that break-in does change Thiele-Small parameters.As for breaking in cables, it may req... | |
| 10 Audio Cable Myths and Facts It's getting to basic ... errr ... I meant getting back to zip cord. | |
| A cable question, sort of... Answer this:A brand new pair of shoes need some breaking-in and that most people would agree. But for some reason, a cable needs breaking-in seems somewhat mysterious. Shoes and cables are made of the exact same materials: electrons, neutrons, pro... | |
| IM Distortion, Speakers and the Death of Science Measuring process, and listening experience in a controlled environment, are not opposites things... They are complementary... I agree. There are still things that are difficult to grasp such as cable breaking-in, an in which case, people are d... | |
| 10 Audio Cable Myths and Facts It's true that electrons move relatively very slowly, but it's the electron wavefront that moves close to the speed of light. It's like open up your water faucet and the water comes out instantaneously. | |
| 10 Audio Cable Myths and Facts Can I be a sonar operator? I mean I don't have any "golden ears", but I can hear just as well as the next guy :-) | |

| 10 Audio Cable Myths and Facts The free electrons in a conductor in an AC circuit move back and forth verrry slowly, a meter per hour. Net velocity equal zero. Whereas the signal itself travels at near lightspeed in wire. Now, think back to high school, which probably won’t b... | |
| IM Distortion, Speakers and the Death of Science "Linear Time Invariant systems are important because we could solve them" Richard Feynman.Once we get into the non-linear things, it can get complicated real fast. | |
| IM Distortion, Speakers and the Death of Science As you narrow down the scope of the problem to some specific variables, then measurements can be used to quantify the "goodness" of that something. For example, it may be hard to judge how good a pair of speaker with measurement, but if the devic... | |
| A cable question, sort of... I've found a similar thread on another forum with this quote which I found sort of funny. Some people would go in great length trying to prove coiling does not make any difference. Notice the words " no appreciable effect", as if there's no eff... | |
| IM Distortion, Speakers and the Death of Science Yes, there are measurements and they are valid, but nobody that I’ve known of could figure out how to measure our "hearing".For example, there is no measurement I’ve known of that can tell how good a woofer is by just looking at the freq. and phas... | |
| A cable question, sort of... No it doesn’t but I have the same degree from less known university plus 40 years experience as a design engineer in electronics (many different fields) and I can judge about somebody’s competence. The fact that you don’t or cannot understand the ... |
