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

jf47t,

Thanks. I may stop by at some point to see/hear what the hoopla is all about.
One more step in this famous "walking" business. NAD C-350 amplifier in a like-new condition (at least visually and, from what I can remember, acoustically). Screwdriver. A few screws. Magical "freeing of the signal" by taking the cover off. Stayed the same except for the questionable looks of otherwise also not the prettiest industrial design piece. True, I skipped cutting the plug off and sticking wires in the outlet, but I did "walk", maybe "crawled". Try it yourself. It was easy. Make sure you keep the screws. You will need them.

Pop Quiz for a slow weekend

Which of the following are tunes and which are tweaks?

1. Springs

2. Wood blocks and Mpingo disc

3. Maple board

4. Cryogenics

5. Heat Tempering

6. Isolating the transformer

7. Removing the chassis cover

8. Elevating cables

9. Isolating speakers

10. Crystals
Michael Green,

Regarding your post on Tuneland that jf47t mentioned above.

First, the pictures you are referring to and that I was supposed to follow appear to be posted hours after I had posted my findings. Of course, I did not expect you would have guessed what amplifier I had available and then prepare me in advance. Nice try, but not quite aligned with clock and logic.


Second, if taking the cover off is important, as it seems to be in almost all of your pictures and has been discussed even on this thread ad nauseam, the effect on the sound should exist. Smaller than if everything you recommended was done, but it should be there. It is not there. Loud and clear, it does not exist.

Now if Glupson (the poster) was doing this for real he would post pictures of his whole system so we could "see" him doing instead of just giving this brief "I tried it troll".
It may come as a surprise to you and jf47t, who ridiculed my statement that Internet forums are words and therefore "talking", but I am not aware of any pictures posted on this or any other thread on Audiogon. From what I know, you and I have posted same number of pictures here. Besides, anyone can post a picture of anything and be done with it. It really does not prove much. Assuming that pictures of that NAD C-350 you posted are taken by you, you certainly know that taking the cover off is not a complicated achievement, That is why I did it. In reality, it could have taken me more time to register for any forum than what it took to "disassemble" the amplifier. It was really easy and pictures still would have not shown you what I heard.

Except for having an excuse to call me a "troll", I am not sure why you would doubt I tried to do it. Most of the people here have done a number of things in their lives and lying to an unknown person in a faraway location about taking a few screws off of some old amplifier does not seem like something they would be desperate to do. Remember, for most of us here this is not a promotional vehicle. We have different careers and no biased investment in tuning/tweaking/music reproduction. I would go as far as to claim that almost all of us would wake up with no fear about our future if tuning/tweaking somehow got banned overnight. I hope it will not, but you surely understand the point.

As you mentioned in one of your recent posts on Tuneland, in fact you whined, you found yourself wondering why people were questioning if you did something in your past. They ended up being "trolls" or whatever word(s) you chose at that moment for questioning that. Well, you just questioned if I had done even simpler and much more believable and achievable thing. I will not call you a "troll" but just so you know.

You asked people to walk the walk, whatever that vague statement means, and I did the best anyone with leftover common sense and a few spare minutes could. Given your approach to demeaning people and defending your, so far, irreproducible results, I am afraid that after I did everything like in the pictures you showed, you could say that I am a "troll" because I did not go to Bora Bora as it works the best there.
"More like a very tiny baby step and obviously the hints of trolling to the sarcastic side, but that’s ok."
More like "walking", small step or not, with plain and simple report of the result.


If anyone is still reading this thread, you may notice that I have adopted Michael Green’s way of thinking to some important extent. That is why I recommend that anyone does some of the cheap things from the tuning repertoire. Most of you may have some equivalent of my NAD C-350 laying around. Take the cover off, do not cut the plug (it is ridiculous idea, no matter how well it would sound), and let us know what you heard. Only then you could say you "walked" for the purpose of this thread. And "troll"? Not you anymore. Someone else.
