The "AES group" includes one or more psychologists and psychiatrists. They are usually the only ones in forum theads who can back their claims about perception with technical books and papers.
And here's one for you: "This is your Brain on Music". Get back with us after you read it.
I've read enough posts to know that bias comes to play as well.
I've done enough hands-on testing to know that bias is very strong, particularly in sighted evaluations.
Thats the reason most of the "all sound the same group" wouldnt make good ABX participants....right?
So far you are a little fact-challenged.
They would have a bias to not hear a slight difference, even if they were told the amps were the same but in realty
they had very slight audible differences, they would have a bias to not hear a difference....they believe so the brain
wouldnt let them hear the difference...it works both ways I assume. BUT they were not the subjects in these 100 or more
verified tests, so I'll have to agree that the participants heard no difference because there was none....makes sense....done deal.
perchance you are free-associating?
I invented ABX and was among the organizers and participants in many of those tests that are in the archives.
What i have a problem understanding is the "why" is that the perfect amp.... at least for me....the one with flat response.
You seem to be stumbling over a gnat.
Nothing is perfect.
Amplifiers are generally specified to have flat response because that makes them into good interchangeable parts for far more complex audio systems.
Most good audio systems end up with equalizers so that the overall system has the desired response which is generally smooth but not necessarily perfectly flat. Since rooms and speakers are all over the map, it is very helpful to have our adjustments all together and properly labelled for easy use.
BTW one of the nicer amps I've worked with is the Crown XTi 1000 and 2000 which have built in DSP-based signal processors that include a number of crossovers and equalizers. If you have configured the DSP for non-flat performance and enable it, the amp is anything but flat. But yet it is a good amp and I doubt that any of the people here who favor DBTs would complain. How is that?
Ok, so heres the thing, I spend many thousands of dollars on high end SS gear, it sounds great. I also spend many thousands of dollars
on good speakers.....its really nice. Then I come here do a bunch of reading and am told that yep my amp is good, but I've overpaid.
What?...ok be open minded, lets check.....I get my bells and whistles $1000 avr out and do some serious listening...over a period
of time I see.....there really is no difference, I try to hear one, nope its just not there. Theyre correct, I've overpaid, on the bright
side I've been educated, and I sell my high price gear, take a small loss....now I'm in the know.
So your complaint is?
Then a while back I decide to buy a small 15w tube amp, very inexpensive....if I remember under $600. I hook it up to my
speakers and audition it out. Its sounds very nice....wtf? So off I go and do more reading, its a crappy amp.....I've been told
it wont measure correct....its low fi.....but....I really like it. Is it bias?.....cant be that, my bells and whistle avr....the expensive one...
cost me much more, if anything I should have a bias towards that. Ok so It must be that I prefer the harmonic distortion...
So you've never heard of sentimentality?
