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

@uberwaltz. I was not referring to you really. A little bit of healthy skepticism coupled with your humor is just fine. I grow weary of the long and repetitive argumentative posts from folks who really just need to move on as they will never enjoy this thread. That’s fine if they can’t learn or agree with MG and others here. However, why continue to derail the thread and waste our precious time as some of us would like to expand our knowledge here. Constantly trying to put a negative spin on someone’s motive and methods is just not what these threads are meant for. Today it seems many think it is exactly what these forums are for. |

It’s been that way since audio forums were invented. Leave it or live with it. If it looks like a duck, talks like a duck, walks like a duck, it’s a duck! 🦆 You don’t even have to look up the definition on Wikipedia. Pop quiz! Is time real or simply a construct of man? If there were no clocks and watches would time still exist? |
amg 56..here is how and why it works..and with further additions pertaining to strapping caps.. theaudiotweak1,676 posts05-16-2018 9:48amSpeakers cones generate shear and polarities of shear before they generate a pressure wave. Thats how speakers work. Polarities of shear on a cone for example travel on all surfaces of the material shape..they also travel thru that material shape. The speed and direction are much determined by that material and shape. Shear can return to the point of emination or the wave launch..this is what we call interfering energy. There are ways to eliminate this interference in vibrational objects that re corrupts the original intended signal. Some methods are easy to see and hear others must be dealt with in new and unique ways or just a new look and understanding of what had always been there. And it has always been there..The best method is the use of a select material contoured with no 90 degree angles and contains a shape angle where shear can be rejected and not allowed to re enter. Some here wish to cancel or eliminate all polarities of shear. If you do so you will reduce all amplitudes of the resulting sound wave. Selective identification of shear polarity and its return into the signal path is what is crucial. Kill all shear..no sound. Resonators work because they capture a pressure wave and change that motion into shear. The size, shape and material's shear velocity determine the sound and perceived quality of the acoustic waves output off of that solid object.Thats why brass, gold and silver objects of the same exact shape generate a different sound out come. Also that's why most everytime you see resonators they are attached to a solid surface or very near the surface. There is an action reaction between a flat material surface :drywall: and a resonator where the pressure wave that impacts the wall and becomes partially shear and travels thru that solid :drywall: That now altered pressure wave encounters a resonator of some size shape and material alters how the molecules of that original pressure wave actually reacts and sounds to our ears brain and body. This continual rotation between compressive and the shear world is what makes sound..and what makes things sound different. Our ears are also shear generators because of material structure and shape we each interpet the compressive wave in a similar but unique way. Oh and then there is the skull and bone structure and mass. Later on..Tom and then my response to the tie down of caps..for that matter anything. You can interchange the word drywall above for the words horrid,glue and sawdust below. The following applies to all material surfaces especially 2 or more dissimilar materials of varied shapes. Adjusting the surface tension changes the surface shear speed of the materials ..becoming either separate,combined or somewhere in between. The result is more or less interfering energy being transferred back and forth between these surfaces in intimate contact or from the compressive world onto a solid then becoming shear. So in many examples of using gucci caps tied down to horrid materials made of sawdust and glue you will have the sound of that cap altered for sure by the larger mass of the material it is forced upon. The size and mass of the same substrate will also give you a different result.The tie down material will also become part of the sound of the cap. As we know vibration is all around and cannot be isolated. We can make vibration a useful tool and most pleasant. Just need to know the why and how..Tom ..

Michael, You still do not understand that I do not understand why or how your explanation works. I am NOT playing engineer here, hence my repeated request for further information. I WANT to understand but you are reluctant to be forthcoming with information that can be useful to posters. Do we need to attend your Temple to be enlightened? I would have thought that these forums, post topics are there to find out and share information on all subjects audio. Why is it so hard to understand? It seems perfectly plain to me. Come to AudioGon, ask a question, search for an answer, if someone make a statement or something that seems out of normal or controversial, why is it so wrong to ask for the writer to seek explanation? Isn't why AudioGon exists? |
Hookay... It seems my very first reply to you in this thread remains as pertinent as ever. Not doing the hobby is when someone speaks as if they have some knowledge on something yet they personally have never done it. But you are casting a wide, disparaging net there. It’s one thing to say of a single subject being discussed "you haven’t personal experience with X." It’s another to cast this as "the hobby." People can be doing high end audio, doing "the hobby" just as much as you are, yet disagree on a subject. Someone could say "Well, Michael, I don’t put tuned wood blocks under my cables because I’m not convinced by your reasoning that it is efficacious." But simply voicing skepticism is NOT tantamount to "not doing the HOBBY." That person can, it should be obvious, still be quite engaged in the hobby of high end audio and their own system. But your way with words doesn’t even allow for the idea that two audiophiles can be in "the hobby," yet disagree on some specific subject. This is the type of careless way with wording that, yet again, is problematic for good discourse. Faking it is the same thing. They will make comments about a subject and yet have never really explored it. Same problem here that I highlighted in my first post to you. First...commenting on a proposed tweak (or whatever) IS a way of exploring it. If you suggest a tweak, and I ask "How does that work, exactly, and on what evidence are you basing this?" then that IS part of exploring the subject. A tweak first has to make some sense to someone in order to motivate putting money...or just time and effort...in to it. Further, there are often times when someone can reasonably comment on a claim that they have not personally experimented with. I don’t have to have gone to the moon personally to argue it’s unreasonable to claim it’s made of cheese, and I don’t have to have tried using homeopathy to point to very good reasons that the claim is based on bunk. Quite a number of high end audio tweaks fall into a similar category, where one can point out the claims are suspect in nature, if not technically, and the vetting process unreliable. So one way to be more clear on where you stand is to answer: Would YOU put me in the category of "not doing the hobby" or being a Faker? Answering this would go a long way to clarifying your stance, and also showing how reasonable it is or not. (Your first reply to me suggested you put me in the "not doing/faking it" camp...but I’m looking for clarification). The reason I asked you if you knew the difference between those two caps is so I could see how experienced you were with the sonic differences between audio pieces. Again...you seem to extrapolate from isolated examples to imply an unjustified wider conclusion. That I haven’t experience comparing those caps does not equate to my not being experienced "with the sonic differences between audio pieces." I’ve been in to high end audio, heavily, since the early 1990’s, and have been comparing audio devices with great fervor for decades. So who are you to try to extrapolate from some simple capacitor example that this disqualifies me from be worthy of discussing with you audio differences? Prof some people swear they can’t hear the differences between caps. That to me is a disqualifier for me to want to talk to them about the sound differences. I didn’t make any such claim that they don’t sound different, right? But you went on to ignore my reply with just "thank you" and no reasoning or clarification beyond that. Same goes for the ties snipped from the caps. I haven’t declared that snipped caps don’t sound different. I’ve given reasons why I don’t just accept the claim at face value, and asked for more details explaining the purported phenomenon. That’s reasonable isn’t it? You see that’s different from declaring they don’t make a difference, right? And yet everything you write keeps implying my concerns are just trolling, and are not serious questions, and even though I keep explaining "I’m not saying it’s impossible" over and over, your replies keep referring to people who say "it’s impossible." I’ve simply been asking for you to interact with what I actually say, vs what seems to be some other version you have in your head that you keep responding to. Fact is, the change did take place and Jay and others here who have gone and done this experiment while this thread was going on heard the difference and reported it to me. I’ve taken my time responding to you because I wanted to heard from folks who actually "Did" the experiment. So this is a problem I keep pointing toward. Your OP made quite a deal about being empirical, and you referenced being scientific. ("why....do people claim they know something without ever experimenting or being part of a team of empirical science folks.") But what I’ve seen from you isn’t very scientific at all. I’ve been asking the very questions someone thinking scientifically would ask: What is your explanation, what makes your hypothesis plausible as a starting point for investigation. Have you measurable results to show? And then, have you tested your hypothesis that the results are actually audible in ways that account for the relevant variables (e.g. bias, human imagination, etc)? See there is a whole world of difference between simply "empirical experience" and being scientific. Flat earthers are basing their beliefs on their experience. But they aren’t being scientific. If you were familiar with scientific empiricism, you’d recognize my questions as pertinent and in fact welcome them - scientists know they gain strength in their hypotheses insofar as they can stand up to skeptical scrutiny. But you keep reacting like skepticism is a bad thing. More like it’s a buzz-kill when you just want to discuss your claims, and only talk of positive results unchallenged. Skepticism is just, apparently, a way to troll you. Such an attitude is much more aligned with pseudo-science, or new age magical thinking or faith, rather than empirical rigor. So you should be able to see the grounds for skepticism here. If you feel it’s fair to call people out for not "walking the walk" isn’t it fair to call you out for giving lip-service to science and empiricism, while not "walking the walk" by actually taking scientific rigor seriously in your methods, and in your responses? Where the talk would come in is all these posts on this thread meant to derail or be a distraction. I would call all those with the intent to derail, troll or just old farts needing attention "fakes". This just sounds like someone who won’t put up with any challenge to his claims. Michael, please look again at your OP. You did not make a thread about your tuning methods. You made a thread specifically calling out some group of people for being fakes in this hobby. Not just that; people you claim are part of this forum. That’s what your entire OP is concerned with, from thread title to the last challenge to these people "why fake it?" Did you honestly think you could just devote a thread to disparaging some group of people...and not have anyone challenge you on your claim? Like you can just gripe all you want about some subsection of people in this hobby and you expect only pats on the back and no pushback? Surely you can’t be that naive. And you even started with the understanding you would be raising hay by saying "you didn’t want to start a fight." But again, that’s like saying "I don’t want to cause any ill will - but some of you are fakes. Just don’t challenge me on that." Numerous people have pointed out this problem in your OP, and in your follow up posts, so I don’t know why you refuse to listen to any criticism and keep blowing it all off, assuming the only reason anyone could pushback is if they are fakers or trolls. Far from "de-railing" from the topic, I’ve been in fact KEEPING this thread on topic by asking you to back up and clarify the various claims in your OP. Trying to see whether I, or anyone else at all here, warrants your disparaging remarks. And probing your claims on empirical testing and it’s implications. It seems you will only countenance on-topic remarks IF they support your claim and pat you on the back for calling out these purported fakes. But if someone challenges your claim...well they are of course the fakes and trolls you referred to. A perfectly circular type of response, more suited to religion than to someone truly empirically open or scientific. For me this is a successful thread because listeners are "doing". Which apparently means "doing your tuning stuff" and that’s "the hobby." This smacks of self-important elitism, evangelism, not of egalitarian respect for other people to have their own approach. I’m "doing" stuff all the time in the audio hobby. And I’d suggest literally everyone on and probably reading this thread is "doing" as well. But your stance continually suggests someone not doing your thing, or who voices any skepticism, isn’t "doing the hobby" or isn’t being empirically consistent, or is a faker or troll. And that’s...to put it more politely than it deserves....not true or reasonable. I didn’t come on this thread to "derail it" but rather appeal to you to clarify and substantiate your claims, and to helpfully suggest - being explicit that I was not accusing you of being malicious! - that creating a thread to disparage unnamed people was likely to be problematic. And...it was. (And it’s not just me...many others have been trying to tell you this). |
