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

GK you forgot to isolate  from neutrinos.   Those little buggers are bombarding your Panasonic as we speak.   The horror!  The horror!!!!  
mapman,

I have SONY D-421SP. Do think neutrinos are wreaking same havoc as in geoffkait's Panasonic? I heard that SONY used more labile photon protection against such pests.
And to think people sometimes accuse me of shooting fish in a barrel. 

"Besides, doesn’t MG use springs?"

Yes. Michael is an equal opportunity tuner. With the rising number of listeners moving from higher to lower mass systems the original audiopoint that MG introduced in the early 90's worked well with some of the amps of that time, but by the time the mid 90's were here the brass "zing" was becoming obvious as products changed their component materials. This is when MG changed the configuration of the cone and the way the outer surface was done. Along with this MG designed and or used other MTD's (mechanical transfer devices) to work better with the newer age of components. If you look at TuneLand you can see the evolution of components and the need for several different types of mechanical grounding methods and tools.

As the changes in materials being used for listening continued to evolve so did the need for different transfer devices. This meant other materials needed to be used along with brass and of course so did the shapes used.

Yesterday MG showed me what happens to the sound as he introduced an Audiopoint MTD Harmonic Spring AAB-R and LTR Block into the system. Pretty remarkable differences. MG is about the variables and took me through 3 recordings and showed me how different they are as well. After we took a break Michael then showed me what happens as a transformer is tuned in relationship to the capacitors in a CDP and Amp. That was a revelation. He explained that only CD Players that use very small and low mass transformers should be used any where near the chips and bigger transformers in CDPs corrupt the signal. MG is giving the system time to settle and after is going to show me what happens when brass is put close to the chips and transformers.
