Yes, that would be pretty safe to say.

The audio consultant Dick Pierce discovered that over a decade ago. He was testing some very well known & very expensive digital gear. It was so poorly designed that they would only work with some digital interconnects.post #1909 of 22762/10/13 at 8:31amQuote:
I remember that. Great guy. Though I always thought he should have stuck with "Richard."

You should, it's the only way to educate people who do not know it.
But as to all shouting numbers...um...I don't hear numbers coming from the mythology camp, ever. Because if they did make a claim like "standard cheapo wire produces an XdB roll off at Y-KHz" because of Z-effect, we'd just go prove them completely wrong simply and easily. No, the number-shouting only comes from people with proof, even if the algebra isn't shown, it's easy to check.
Everything you need to know is pretty much out there already, published, and possibly there's a web-based calculator that does most if not all of the job for you.
You know as well as I do that a believer will never bother to look up the algebra themselves. Which is why I feel it should be posted here, preferrably in a way that is easy to understand. Also stating "I use actual numbers while the other camp doesn't so I am right" is really pushing it
So, you take me to task for not publishingthe example, yet no problem with somebody who says "Oooh, watch out for the capacitance, or impedance (we never touched on that one..) as if that were fact too.
That is not the way I think about it (not sure how you got that from my post), on the contrary. Again, which is exactly why I feel the proper way to counter them is to not use their typical way of providing inaccurate unverifiable nonsense but instead hard scientific proof whenever possible.
As much as my lack of "proof" may have upset you, people posting comment without Googling the concept first annoys me too.
I got thatpost #1914 of 22762/11/13 at 6:14am
Yeah, thanks, you're right. I just got a little frustrated, my bad. Check my recent post over on the "If it graphs bad then it is bad" thread. See if you think I've done any better.post #1915 of 22762/11/13 at 8:34ampost #1916 of 22762/11/13 at 10:43amQuote:Originally Posted by drez
IMo the ability of science to account for the experience of life is very limited, I don't mean that it is useless or incorrect, but just limited in what it can predict. For me my direct experience comes first and foremost above a priorised mentally constructed determination of what my experience will be. Science enters to help make sense of what I directly perceive.
For example I just bought an HD800, and seller says look at the FR chart there is no 6Khz peak, and sure the FR plot provided shows no peak. But my ears tell me otherwise, so I look into it further and the FR plots made by Sennheiser are absolute rubbish. If I were to assume the evidence provided to me was absolute and reliable, and that my own observations are feeble and worthless I would still have sore ears. On the other hand objective measurements help to determine what might be causing what I was observing. Still other people might listen to e exact same headphone and be perfectly happy with them, even with all things being equal.
6 KHz sounds like a resonance in your ear. Read this http://www.head-fi.org/a/how-to-equalize-your-headphones-a-tutorial
Science wins again.post #1917 of 22762/11/13 at 4:35pmAnd yet somehow the pattern I perceive is pleasing to my eye. I'm going to have to change the brand of tube wax I'm using...Quote:Originally Posted by stv014
If the observation is not made under properly controlled conditions, then there is no evidence that it is true, and it could very well be false, even if it is the same for the majority. If you look at this picture,
do you trust your observation that B is a lighter shade of grey than A (especially after it is backed up by 10 out of 10 other people looking at it and also saying that B is lighter), or the measurement tool of the image editor that says that they are exactly the same ? What do you observe now, with the source of bias removed:post #1918 of 22762/11/13 at 4:54pmpost #1919 of 22762/11/13 at 6:18pmpost #1920 of 22762/11/13 at 6:55pm
Initially counter clockwise and then clockwise after looking up the wiki page (but before reading the article, strangely)
Closest I could think to this sort of phenomenon in audio would be the illusion of stereo imaging. This is an interesting talk from the editor of Stereophile, as well as a cheeky dig at the opposition:
