In Reply to: RE: Cable shootout... Are all audio cables the same? posted by geoffkait on June 24, 2014 at 03:26:27
Wow, a "gold star" for persistence, the consummate audio salesman type, unfortunately untainted by engineering and also possibly hallucinating.
For example for hallucinating, what article are you talking about that “I linked” talking about directionality and a number of your assertions such as; “Sine waves are not alternating current. Nor do audio signals produce alternating current. Hel-loo! The audio signal is the thing that's moving at near light speed down the track. “???.
The thing I linked here was about cable velocity which is 100% engineering related and says NOTHING about audio or directionality unless you can read what wasn’t printed or intended.
At the same time you avoid addressing any of the things I brought up and say silly things like;
“Nor do audio signals produce alternating current. Hel-loo!
Hel-loo Geof, your right we ARE a LONG way from a meeting of the minds, you’re talking the language of alchemy and audio trinket sales, I’m talking the language of chemistry and electronic engineering and design no wonder there is no common ground and your unable or unwilling to answer even my simplest engineering question with a direct answer like;
“Ok, i am game, in exactly what way are they directional and how large is that effect an alternating signal like audio?”
Sure we can hear things, but we also "hear" things unrelated to what arrives at our ears and influenced by what we know and believe.
If this signal directionality and “audio is not an ac signal ”is a real effect, it exists in the electronic domain, not just in one’s head, show me some evidence of that.
Sure I am skeptical, audio has been a lifetime love, I have worked in both electronic and RF engineering most all my life, much of that time designing circuitry that works, even flown on the space shuttle (sts-7 and sts-51a).
This makes it rather hard to believe here is something about audio traveling down cables that isn’t present at all at frequencies above 20Khz or below 20Hz..
You said “I suspect this might be another case where someone has fabricated a theory of convenience to explain a strongly held belief that wire directionality is false and ALL EVIDENCE to the contrary further buttresses that belief.”
Show me engineering evidence, any evidence at all, some mechanism, or measurements this exists in audio for directionality, where it doesn’t for RF, more arm waving and smug salesman talk won't do it..
I was quite sure this "discussion" would deteriorate into name calling and silliness. Thanks for making my prophecy come true. Some people refuse to come out of their caves.
Similarly, from the start, i pretty much assumed you couldn't answer in an engineering fashion or answer even one question honestly, but is was fun to see how far you would bend before bailing out.
Fwiw, Engineering isn't silliness, its what honest design depends on but it's never to late to learn something new, hence a number of sincere attempts to get you to explain directionality leading to the conclusion you can't and are an alchemist in a world of chemistry.
More jibber jabber from the man who lives in a cave. An engineer, a real engineer, would have gotten to the bottom of this whole wire directionality thing a long time ago. You rely on phoney arguments like "voltage velocity" and other pseudo engineering terminology. It's apparently true what they say, you can't teach an old dog new tricks.
Why Geoff I am glad to not be your kind of engineer in fact I am an inventor and here are a couple samples of what I have done “living in a cave” as you put it;
The first invention link might even appeal to you especially as it looks like magic to most and all are the result of understanding how things work;
Would “your kind” of engineer have inventions which changed the way things are done, some examples;
Or would “your kind” of engineer have changed the face of large scale sound in just a few years?
Have you ever been to a stadium and heard what concert speakers sound like?, they don’t sound like this.
Pop on some headphones; By this fall, 4 years after introducing the products, we will have provided the sound systems for more than half of the 100,000 seat stadiums in the USA.
Soon there will be several recording studios using our smaller Synergy horn loudspeaker systems for monitoring audio too and next season we are introducing a new “stereo capture” system which can capture an entire hemisphere, try a recording or two, again use headphones.
So, this is sort of fun, teach me a new trick Geoff, somehow in some way if at all possible, try to describe how / why audio signals aren’t AC and audio cables and wire are signal directional.
