Not open for further replies.
Not claim but a reminder to other readers who aren't yet familiar with certain posters.
What is his commercial interest? If you can't back it up, it's a claim.
If posting the words shill, snake oil salesman is in violation of forum rule, mod/s would have done something about it.
Read Rule 1. I guess you don't realize the mods don't read every post, and as Markw4 pointed out, this thread is considered a little less strict.
Real smear campaign is coming from those with audio business interest against DBT.
Please explain how criticizing certain DBT practices (not all) benefits anyone's business if we don't even know his business? Do his presumed customers buy more stuff because he mentions controls in DBTs? ...in DIYAudio!?!?
 
With regard to this whole subjective vs objectivist thing.

In my book it’s quite acceptable to describe subjectively how something sounds. You put some opera on, the recording is great, the system is faithful (whatever your interpretation of that may be) and you go on an emotional journey.

The problem of course with this whole thing is when people try to ascribe their emotional experiences to technical aspects of the equipment and then open themselves up to ridicule by those who technically are highly proficient.

I am very comfortable describing my DIY amplifiers as sounding ‘liquid’ and ‘light and fast’ or ‘having an expansive sound stage’ because that’s what I experience when I put a record on and sit back to listen. That’s the soft, emotional stuff which is exactly what music and art brings out. But I draw the line for the most part at explains those experiences in engineering terms. Electrons feel nothing. Neither do transistors, or speaker cables or any other physical part of a Hi-Fi system.

And, whether people like it or not, visual cues play a seriously significant part in all of this. How many of you, after two or three glasses of wine at dinner in a nice restaurant have not looked across at you wife and thought ‘damn, you are beautiful’. It’s the same with Hi-Fi, but you can get that feeling without the alcohol. 😀

The problem in all this arises when people coming from the subjective emotional side try to explain their experiences in electronic engineering terms.

Sorry, it does not work. It’s like trying to explain to an atheist why praying makes one feel good. There’s no connection there.

And the same applies in reverse of course.

So, kick back, have a drink, enjoy your music but don’t try to explain why it makes you feel good because you’ve just replaced a 10 foot $5 mains cable you used to quickly lash up your speakers with $1000 Nordost’s.

😀

Spot on. The only other issue is when folk confuse a perfectly reasonable subjective feeling with "I'm right". Subjective is subjective. Music is subjective - we all like different things. and even we like the same things, we like them differently! Vive la difference!!
 
^Jakob3? 😀
😛 Nope. Jakob (and MM) and I disagree on some major issues. I don't belong to either tribe that snipe back and forth. I'm an open-minded skeptic. Yes, I know the joke about having too much of an open mind, so my brains might fall out. :rofl: But I'm open to new ideas if they are backed up.
I particularly dislike unfounded smearing. If you don't like someone's post, argue (even attack) ad rem, not ad hominem, and I'll be happy.
 
To the phase?

Can’t pin it down exactly but yes anytime I change up something that affects phase it seems to move this in or out of focus.....

Like right now I’m right on the edge of it but have a pretty nice sound going otherwise......Something tells me the best place might be right at the edge.

The edge of what I have no idea.....that’s why I bring it before the braintrust.

To put a little more subjective explanation behind it......it seems to be when the soundstage envelopes you almost as if you were one with the music, micro details become abundantly clear and relevant.

Where do you think the focus ought to be regards psychoacoustics in the audio equipment chain?

Have you tried listening nearfield? I presume your speakers are positioned sensibly? We had a very strange set up described a while ago.

Really? If your selling snake oil you have to make the buyer believe. The only way the buyer will think he hears a difference is to not do a DBT, so you have to make sure he thinks that DBTs dont work. So take your snake oil home, install it and listen, no switching back.

There’s nothing about the way it’s set up right now that would lend itself to near field monitoring.

Speakers are 8’ apart, The subs are centered and overpower if you move too far fwd.

Positioning is tweeter just above ear level ....there is nothing behind the speakers open to below in a loft

But it’s not positioning.....I was getting the same results when it was setup downstairs (2’ from the wall) where it’s going to end back. (This is temp until cabinetry is done downstairs)

For the end user or the designer/engineer? I guess the answers are the same: where improvements are needed, and either when solutions require trade-offs or when the solution is not obvious. By chain, I assume you mean from instrument to ear canal, and it would seem one should start at the weakest link which one can control/change. We have little control over the microphones, but we do over the speakers/room!
I'd bet the biggest influence in the next decades will be spatial sound, and I'll predict the solution will include IEMs with head tracking.

What is this post good for other than for stirring up pages of pointless argument? The thread finally got back to some almost readable posts.
Apologies if you think I stirred up the pot. And I admit I've only read the last few hundred pages, but I don't sense any real change in the mixture. This whole time there have been many readable posts mixed with many that are less so. I was calling out what I saw as "less so".
 
I’m learning.....

By the time I get done here my innocent views on audio will be put through the cynical and opinionated objectivists meat grinder and stuffed into sausage casings to be fed to syn08 and evenharmonics!

One of those is an eccentric if outspoken objectivist. The other is in a league of his own that highlights all the ugliness of being an ignorant pseudoscience purveyor.

Most importantly, know you're ultimately (hopefully) gunning for your happiness, however you get there. Which may or may not translate to anyone else.

Thanks Daniel, yah I get it; that was just cheap humor!

I am trying to share something I’m experiencing that seems to be relevant in audio research at this time.

It seems many don’t grasp exactly what I’m saying and the ones that do are on the defensive against constant ridicule.

So in the face of adversity I trudge on 😀

Who's selling snake oil? Are Geoff Kait or Peter Belt posting here? What are their usernames? Is EVERYONE here who sells an audio product selling snake oil?
Who is saying that ALL DBTs are useless? As far as I can tell, most people here would agree: Properly performed DBTs are useful. Poorly done DBTs are useless.
Where I disagree with many is how to define properly/poorly, and whether lay people can do them properly.
It seems that for a particular group here, anyone who points out issues of experimental design that the group is unable to intelligently answer must be selling snake oil. Attack the info, not the person! Attack ad rem not ad hominem.
Unless you can't, in which case, continue displaying your lack of understanding...

Golden words. All of them and especially the one I highlighted that could be cut in two rather in four.
