No, we disagree here. Your most important part is the ability to create stories that, if good enough, can sell a high end audio product. Also the ability to adapt these stories to what the prospective customer wants to hear.

What I find truly amazing is how you appear on a DIY forum with an “I don’t want to reveal” part about your original amps, and at the same time state that you are not following any commercial interest. So I have to add to the list of your traits the nerve and cheekiness absolutely required in a successful high end audio business. Good luck.

You are exactly right. I know how it works, regarding creating stories etc. But i don't have these skills. And my morale is much higher than the average. I have failed in businesses unrelated to audio. Now I'm only thinking about business possibilities making use of high level knowledge like programming and robotics to solve problems, to restrict the competition. I don't like the global free and 'brutal' market currently we have.
 
Why not presume it's all equally important, isn't that the simpler more logical thing to do?
Current measurements don't do that & you will never get an playback waveform at ears that exactly matches the input waveform so what tolerances do we use, what parts of the waveform do we focus on, what weighting do we apply to certain factors in the waveform, etc.
I don't know, do you, does anyone, and what waveform are you talking about, the one that hits your ears?
@scottjoplin, your points are clear, simple and unassailably logical. How can, and why would anyone look anywhere other than under the streetlight (link)!?
I think @mmerrill99 is saying (correct me, mm), we should look for the keys in the park, even if we don't know how... yet!
He is rejecting the idea that if we can't measure it, it doesn't exist (link).

The world we live in is built by brilliant, creative people who work under the lights. The "key" to changing the world is to figure out how to see in the dark.

Jam should have a good future ahead of him. I am moving to Asia and gave away a lot of my test equipment to him. Parts stocks also.

A lot more going on in Asia than USA. More fun there now. And, since we have little to no manufacturing in USA anymore, I can still build and test new ideas in Asia.

High end is alive and well there. Did you know that Thailand (Bangkok) has 91,000 millionaires and 324 billionaires? Thailand is now the number one distination country for vacations - 30,000,000 a year dropping money there on vacation. Lots of room to sell high value and high cost audio products plus a growing (rather than shrinking) middle class.

Centrally located between India and China and Australia... that whole region is booming.

Yes, S&M, the park is a interesting place with lots of interesting things to be discovered,imo even though some are scared by it & prefer to stay under the streetlight (it eventually gets boring just hanging around under that light)

Sorry to stretch the allegory to near breaking point :D

I simply said that I don't care which set of claims about the modulator (JohnW's or Martin Mallinson's) were correct. Somehow you have managed to take that way out of context and make a useless generalization, congratulations.
Lack of curiosity (I don't care) is one of the main reasons for staying under the street lights
 
I think both. There's aspect that can 'easily come and go' with any system being tweaked, so here it applies to me. But I think it applies to general system too because many systems for example cannot produce musical electric guitar and think that guitar distortion should be fatiguing. Many speakers also cannot cope with high level midrange frequencies. When there are so many things wrong how can one expect to hear the 'truth'?

So you get it:)

I noticed since I started playing around with pro drivers for home use that a pro 10” mid bass reproduces electric guitar like no other.
Considering that’s actually the ‘source’ sound it’s not surprising

I’ve always had this oddball idea since back when I was heavy into live recording.....mic every instrument, down to every drum,symbal etc
Level it then send every mono signal through it’s own separate amps then into separate (appropriately matched) speakers setup/placed exactly as the ‘band’ would have been.....could even go as far as using matching guitar amps etc.
A virtual band!

Wonder if anyone’s ever done that?
 
how we interpret music is kindly the final frontier in audio design....no?
Perhaps. What I do know is that people are free to experiment all they want to get a sound that is "good enough for me". Wesayso's thread, to my mind, is probably the best example of this on the entire forum. When it comes to finding the elusive "things that are not presently being measured" then the feeling seems to be that no one is prepared to invest in what Mark presumes, probably correctly, would be a very expensive undertaking.
 
I do think it’s all relevant, how we interpret music is kindly the final frontier in audio design....no?

And I don’t think it’s nearly as individualized as some portray it to be.

I agree & Harmon have done blind preference testing of speakers which seems to show that generally people (trained & untrained) rank sound in the same gradations 1,2,3, etc which is not particularly surprising as we all have roughly the same physiology & our auditory perception uses the same internal schema by which sound is analyzed.

Of course we have all been down rabbit holes where we chase a particular concept of what will deliver great sound only to find out that we were wrong in this particular path/quest. The following of a particular concept is often most strong in audiophiles who care about sound passionately (maybe too passionately) & this bias affects everything they listen to.

Often those who aren't so passionate hear more objectively & recognise when replay sound has improved - this is often seen in women (yes men's egos & need to be right can often prevent them from objectivity). So this idea that we all hear differently, IMO is rooted in & allied to the notion of bias affecting how we perceive sound. But not everyone has this strong a bias.

Sure people are free to experiment & get their version of 'great sound' but often when they express this on here they are challenged/demeaned such that it is a disincentive to people to express their observations.

Why not let everyone discuss what they have found/experienced (including the ABX crew) & treat all equally - distilling from these observations areas of investigations which are worth personally looking into?

The first step of all scientific investigation into how the world works is observation & audio forums can be a great source of reports of observations from the world of audio

For the ones that holler bias at every subjective observation.....what if there’s no bias to start with?

I seem to have the ability to shut off my brain and focus on the task, if that task involves testing my own gear why would I lie to myself (or anyone else for that matter?) I really don’t care enough about others ‘feelings’ getting hurt or my own ego getting bruised.

You put anything in front of me and your gonna get my honest opinion no matter what, even if you don’t want it!

I love destructive testing.....pushing things to (or past) their performance envelope tells me what their really made out of.....if it survives the mountainman it’s worthy!

On the other hand the testing that involves hearing subtle nuances as in this case definately has a learning curve for me but still the integrity is intact.

Blind testing certainly gives results but are they real in the manner that it applies to the test subject? And they’re set up to confuse...that’s just wrong.

My testing is real for me, real problems.....results are real and repeatable, probably even measureable!

The only problem I’ve got is I don’t know what I’m doing half the time!

although that could be to my benefit:D

Yep - Asia is where its at - it was already the case 10 or 15 years ago. The place has a fabulous vibe with so much energy.

Trust you will have a smooth move and best wishes Richard.

No one is free from (e.g. expectation) bias. Everyone has different level of it. For one, when he sees white object moving above him, he will think "I saw a ghost!". For the other, he will think "I think I saw white object! It could be ghost, optical phenomenon, someone making fun of me, could be anything. I don't have enough data to draw a conclusion of what it is."

Try a FoobarABX, you may experience the moment "I'm sure A is X!" but it turns out that A is Y. Our experience will shape the 'level' of our bias.
