Talk but not walk?

Hi Guys

This isn't meant to start a fight, but it is important to on lookers. As a qualifier, I have my own audio forum where we report on audio issues as we empirically test them. It helps us short cut on theories and developing methods of listening. We have a wide range of systems and they are all over the world adding their experiences to the mix. Some are engineers, some are artist and others are audiophiles both new and old. One question I am almost always asked while I am visiting other forums, from some of my members and also members of the forum I am visiting is, why do so many HEA hobbyist talk theory without any, or very limited, empirical testing or experience?

I have been around empirical testing labs since I was a kid, and one thing that is certain is, you can always tell if someone is talking without walking. Right now on this forum there are easily 20 threads going on where folks are talking theory and there is absolutely no doubt to any of us who have actually done the testing needed, that the guy talking has never done the actual empirical testing themselves. I've seen this happen with HEA reviewers and designers and a ton of hobbyist. My question is this, why?

You would think that this hobby would be about listening and experience, so why are there so many myths created and why, in this hobby in particular, do people claim they know something without ever experimenting or being part of a team of empirical science folks. It's not that hard to setup a real empirical testing ground, so why don't we see this happen?

I'm not asking for peoples credentials, and I'm not asking to be trolled, I'm simply asking why talk and not walk? In many ways HEA is on pause while the rest of audio innovation is moving forward. I'm also not asking you guys to defend HEA, we've all heard it been there done it. What I'm asking is a very simple question in a hobby that is suppose to be based on "doing", why fake it?

thanks, be polite

"Brass is also more sensitive to temperature change and humidity change."

I get the temperature part, but am surprised by humidity statement. How can brass be more affected by humidity than wood? I can imagine some oxidation taking place and changing properties, although I would expect that to be a relatively slow process. Wood, on the other hand, swells and what not, when exposed to the water/humidity and effects I have seen so far can appear overnight, if not sooner.


Is there a secret in wood processing. painting, or something else, that makes wood less susceptible to humidity exposure than brass?


As much as I understand the conceptual idea behind it, isn’t this statement contradicting the above statement about wood and brass?

"...whereas wood responds to nature because it is nature."
Wouldn’t one then expect wood to respond to changes in nature (humidity of environment, in this case) more than brass?


I cannot tell birch from oak when I see it in the park, and am not running for an amateur hour award when it comes to audio. I will not get a professional one, either. But I am trying to connect dots and would vote for wood over brass in anything at any time.

Whilst brass can be effective for audio apps, especially with the right ballistic shape, as fate would have it brass is a *relatively soft* material and as such does not transfer energy out of the system as rapidly as much harder materials, especially tempered and cryod high carbon steel and NASA grade ceramics. I did not create reality.

Gee, I must have taken strength of materials and indeterminate structures in school. 😳

This is great.  Battle of the footers.  Today's card includes APs, MTDs, and now DH cones.  Where's Mapleshade? Anyone see Herbie? Myrtlewood anyone?   

I am still trying to figure what is inside the Mpingo disc..... 

1. Nothing - we ruled that out
2. Morphic Message - a possibility but redundent with the writing on the outside
3. The word REDRUM - "Here's Johnny!"....this oft-used cliche is doubtful 
4. Tiny crystal - the frontrunner imo....audiophiles love secret crystals and Dr. Kim was a professor in quantum physics....sort of like that Bybee guy that uses "crystal technology"
5. Graphene - I doubt it - this didn't really become popular until after the Mpingo was coined 
6. Small rare earth magnet - a possibility, but my money is on the tiny crystal

Am I getting closer?

A piece of mud from the lake near the trees harvested for Mpingo discs. It achieves unity of those two with mystique of well-known healing properties. It focuses the Earth vibrations on the center of the disc from where it spreads shimmying to the music of an ancient tribe that first used the tree for sound.
