Yes they might. If properly conducted.

"My contention is that, if there was a difference heard and we wish to ABX test it, then altering any part of the system (except the component under question) sorta makes any result thus obtained pretty meaningless."
Yes this seems basic to me. Not all DBTs that upset the subjectivists have been done in a lab or unfamiliar surroundings. I have done simple blind tests in my home and really upset myself. It was only after this that I started to appreciate just how suggestive I was. I believe if more people on this thread tried a simple test, minds would change.

OK, I must have missed that too, popcorn and all.nunayafb said:No Brett not the link, thank you for that. No I proposed a theory about how small head movements would affect the spectral balance, just a mm or 2 would have significant effects at higher frequencies.
It was ignored, repeatedly.
I think you and Ethan are correct.

I would like ask at this point.....
When did people last change their interconnects or speaker cables.. and why ?

Gees, that sort of response must make it basically impossible to tell which instrument is which, and where they are located in the
soundstage. Move a few inches and everything would sound completely different.
Who has noticed this ?

I believe in this. You get up to change your cable, when you sit down you are not in exactly the same place so the sound IS different even if you actually didn't change the cable.

What? isn't your seat molded to your body shape yet ? 🙄
I have read nothing in this thread but try this.
Stand in front of a small group of people.
Give a glance over the group.
Now close your eyes and blow out air through your nose, 3-5 times.
Now slowly open your eyes and glance at the same group in front of u.
Is there a change?
Find for yourself

I am talking of tests done. In the future man's hearing may improve and DBTs will give a different result.Andy Graddon said:Yes they might. If properly conducted.

makes you realise just how incredibly clever our ears are compared to microphones, doesn't it !!
Have you never seen an in room measurement (sweep) of a speaker at listening position? That's what it looks like.Andy Graddon said:Gees, that sort of response must make it basically impossible to tell which instrument is which, and where they are located in the

Now go measure on of your speakers at the listening position with a sweep and some decent resolution and post it. Then you might get what others have been saying for a while.
Not completely, but noticeably so.Andy Graddon said:Move a few inches and everything would sound completely different.

And yes, if the tests improve , that may also give a different result.

DOH ! Many times !! I KNOW this is what it would like !
How do you think this related to what we actually hear ??
Apart from spatial cues and detail, how different do good speakers sound compared to a pair of headphones with a flat frequency response. The sort of measured frequency abberations measured there would surely have major impacts on tone, timbre etc etc Is this shown vs headphones ?
You know this, but the tiny possible effects are cables are still consistently audible to you?Andy Graddon said:

Instruments sound different in different acoustic environments and we have evolved to adapt. Instruments played outside sound very different to the same ones inside. Ditto speakers.Andy Graddon said:How do you think this related to what we actually hear ??

[/B][/QUOTE]Headphones aren't always flat, but are much, much closer than a speaker/room. When I was playing with amps a lot, I used my STAX to test for changes as they're the highest resolution, most consistent listening system I've ever heard.
Andy Graddon said:And yes, if the tests improve , that may also give a different result.
This is where you and I differ. I think the tests are perfect now. You think they are not perfect. I assume it is because the results don't support your personal experience. They don't support my experience either. It is bizarre.
Brett said:You know this, but the tiny possible effects are cables are still consistently audible to you?
excuse me? please find one place where I have stated that.

I guess the answer you want is nobody hears this? So for you here is another example of measurements not corresponding to what you hear. In actual fact they do correspond. The mic is measuring real phenomena. What you see is the same signal that impinges on your ears. Your brilliant brain then makes sense of it, "that is a sax over there". When your head moves just a fraction the signal changes a lot but your brain is able to ignore that as it is focused on that sax. You do not realise just how brilliant your brain is.

Oh, but I do !!!

That is why I am constantly amazed that people want to put basic measurements and basic theory "above" what our ears tell us.

That didn't come out right..
I meant, the human brain in general, not my brain particularly.
