All this blather when you could have just answered "yes" you've done double blind test or "no" you've never done it. 🙄
Then why did you use the phrase "may be" on post #336?
I have observed that in your discussions you often make a reference to an older posts, post in different thread, and I think also post in a different website. It means you do investigative works. It is hard to believe that you haven't found out either from my statement in the past or by deduction that of course I have done double blind test. It's probably normal for you to keep asking "Are you in audio business?" when you sure remember you have asked the same question and got your answer.
You thought there is an effort to blur the line between Electronics and Psychology for business interest and I said may be it is just their honest views about audio, long before they have their business and they just carry those views, understandings and knowledge with them anywhere. I don't know whether people you addressed are in audio business or not, but I know that (1) I'm not (2) The subjective views about audio is naturally not driven by business need but stem from inability of the experts in the field to explain some phenomena such as why there is little correlation between numbers and perception. The less their electronics knowledge the more the confusion. Your 'target' should be those with high electronics expertise like Bruno but you don't know whether they really don't know everything.
beyond all this non sense, a good argument for discrediting blind tests A/B or X is that most people have no taste.
Only 0.1% of people have taste and it is mostly acquired, maybe a part by birth, the other by education, and the other by money. If people had taste, the good audio gears out there and the good food would be so scarce it would be frightening. I would never ever be able to obtain some of the things that I like a lot, if 99% of people had taste, or my tastes.
It doesn't mean that fast-food doesn't taste bad, but there is something beyond that and good friends to share too is important.

Then why do you post such nonsense quoted below when responding to Bill Coltrane's "Double blind testing is bias free."?
"Only if you get positive result. And you don't get positive result in an instant." (post #359)
Perhaps you don't really understand DBT as if you've never been in one before which led me to speculate that way.
And lets not forget the posts #255 and 260 of this thread.
You sure did (in bold) speculate despite your claim that you don't do speculations.
BTW, not all posters who are in audio business post the same way. Some do hide their identity and intents. Lets also not forget what others have observed from your posts.

That's grainy gossip!
Now I'm hearing a very high freq hiss, probably HF trash from tv, chargers, the refrigerator...
Or am I suffering from ...acufeni!?
Preparing a coffee to push away that ghost!
😱🙄
I mean, this is grainy sound. What is the origin? The refrigerator, probably mechanical. The electronics, a mix of mechanical ( do transformers operating at 50 kHz ring ?) or electromagnetic induced .

Just a wild guess. Could be IM product from SMPS and inverter hash. Other possibles is non smooth phase variance of generated harmonics vs frequency.
Yes, the so-called beats ( that slip into audiofrequency)
The switch on the back of the radios used to be labelled as Beat

But that looks ( hears ?!) like an infinite sustain, and indeed it's rather philosophical ( the infinite, ad libitum) and incorporated into 'the flowing of time' concept ( which is rather natural. I'm alive, I got my five senses, what else? !) which can be easily put under sub-routine task
Just a wild guess...

Do you remember that I ever challenged you into an ABX. Not only you, but I mentioned anyone that you champion and stated that I will beat you at every turns? That's not because I have no experience with it.
If you get positive result from an ABX, what is the unbiased conclusion? Answer: there is differences. If you get negative result from an ABX, what is the biased conclusion? Answer: there is no difference.
Sometimes we can feel there is differences but we cannot pass an ABX. If we stop there, the conclusion will be different than if we persist and at last find out that the difference is so obvious. I experienced lots of things like this. I know the correlations between most of what I can hear with numbers. I have built my own method to lower a lot of 'distortions' not present in normal THD test. But may be I'm the only one who can hear the difference?
It sounded like I'm dismissing engineering or Physics so I can sell something based on voodoo, but I'm not. Even if I had this technique to remove distortions, it doesn't mean I'm interested in selling amps.
What the f are you talking about.

Details are different for every test.
Imo the science guys kinda know what they're doing.
And if they don't, peer review will stop publication.
Believe it or not I thought it was quite clear (for Pico) I'm interested in his clarification, if one is forthcoming, so don't want to say what I thought he was talking about. But, perhaps if you consider his question........
A very simple test for prat:
Record a system with high prat and one with low prat. Then see in a daw how the music lines up.

Well, lets see, I have experience with formula 1 car. Does that automatically mean I understand it to the point of being able to use it fully to the extent that it is designed for? No, but I have experience with it.
Which alternative ABX universe did you gain experience from? As Bill Coltrane put, what the **** are you talking about?
I can feel that you are in audio business and trying hard to disguise it.
Feeling = fact?
Bigun,
Sense qualities are expressly unmeasurable, undefinable and unanalyzable. I learned this from Aristotle back in the day and I never said otherwise. Unmeasurable entities (including events) can only be assessed subjectively and the interpretion of quantitative formulae occurs in subjective qualitative terms as well.
Unlike sound, amplifiers can be described using demonstrable attributes in order to make things comprehensible. That's my point. Anyway, I like it when you are observant.
Yes. If there is such an information. More often than not, there is not.
Illusion? Yes, but it is also the only reality.
PRAT - Another paragon of stubborn idiocy.

Exactly what? That you are in audio business and my (gut) feeling was right because it turned out to be a fact?
