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

Michael Green,

Why wouldn't an, for example, amplifier work to manufacturer's specification once received straight from the factory? Ties, rods, rings, whatever else, in place as manufacturer left it. I am not talking about some packaging material, but about a finished product taken out of the box? Why shouldn't we expect that manufacturer, when tweaking and finalizing before releasing to the market, is testing the product as customers would use it? In fact, why would not manufacturer do it? I have a hard time believing that someone engineers a half-baked product and never pays attention to how it sounds when finished? I am sure it is possible, but why would anyone put time and effort into engineering something that she/he would not adjust as the finalized product? Regardless of personal opinion what does or does not sound "better" (tied or untied, etc.). Or, did I completely misunderstand your post, which is also very likely?

If it is only about removing vs. not removing shipping material (as it seems is the case in your example), why would anyone not remove it? Even if you forget the sound, which may or may not be different to someone's liking, the machine would not look the same as what you envisioned when parting with money.

When you have too many parts too close together the parts are not able to perform at their spec. This actually causes blockage of the audio signal and makes the soundstage start to collapse or get congested sounding.

This is an interesting one. It seems that when parts inside some equipment get congested (capacitors etc. closer together), the virtual image of the performance, as heard from your listening position, also gets congested (musicians closer together). Serendipity at work? It would be interesting to know why would that happen just like that. I do not doubt many things (including this) can happen and that is why there are good audio equipment engineers out there who think of all the details, but this one is, kind of, funny. Almost makes me think that, if amplifier is turned to one of its sides, I should expect to hear a cellist sitting on top of a violinist.
glupson,

Nice to see people like yourself bringing critical thinking to MG’s claims.

They apparently don’t allow too much critical thinking on Michael’s forum. Skeptical challenges to their ideas - simple things like asking for measured results for some of the more controversial claims, listening tests constructed to control for the variables of people’s imagination etc - are frowned upon as "bad vibes" and a sign one is not being sufficiently open minded. (You’ll find exactly this attitude on any number of fringe medicine, New Age, psychic medium, astrology, etc groups...funny enough).

There isn’t the luxury of of fan-worship and lack of skepticism when he brings his claims here. (Though I’d like to be wrong insofar as he could actually substantiate some of his claims). So I’m sure it’s not as comfortable for those claims to be brought here.

But then: A wise university professor pointed out: Discomfort is a sign that something that you think is right, is being challenged. And that should be exactly what you want, because that’s exactly when you are most likely to be on the cusp you are learning either that you are wrong - or by taking on the challenge you gain more confidence you are right. One can either take that opportunity to be challenged and learn from it, or use the discomfort to declare those who challenge your claims as "trolls" as a way of running from the challenges.

As for how the crowding of the electronic parts producing crowding of the soundstage, you’ll find quite a bit of these folksy-level "explanations" in MGs stuff. For instance he’s written how running wires close together would produce a "tighter" sound, a bit more apart will yield a bit more open sound, moving further apart yielding even more open sound.

As I said, it’s something of a piece of the folk-wisdom behind homeopathy - the same conceptual appeal of "like cures like" (even though there is no actual basis for the claims made on this hypothesizing).





Sounds like hifi voodoo. Literally. Would like to see the empirical evidence of that. Some kind of cult?

Tuning sounds a like lot what many here would call tweaking.   Semantics I guess.

The mysteries of HEA. Queue the spooky music!

Hi glupson

I don't want to answer for HEA companies, but I will say, that when listeners start to tune their views change quite a bit toward manufacturers. I also know for a fact that many guys and gals who start tuning sell off their massive components and get products that tune easier.

To Everything tune, tune, tune eh?  

The tunable speakers are interesting.   How does one tune them and what changes physically with the speaker when you do?
