Read about acoustic and psycho acoustic and forget " gear listening fetichist" and their rejection of blind test and forget " measuring tool fetichist" and their embrace of blind test instead of their own ears... These oppposing camps are united by the SAME ignorance...
I am not against the use of blind test by the way...
But using his own ears like acoustian learn to use them is the key to audio...
And the materials you put on the wall and the cheap homemade device you will use dont need to have a price tag but need to have the right physical amd mathematical acoustical properties...All my acoustical devices cost me nothing and we dont need blind test to tune our speaker/room no more then we need blind test to tune a piano or to verify the tuner hearing, playing the piano will do the test...
Is it not simple to understand?
And dont try to test other people claims, it is a waste of time, learn how to listen in your own room...
😁😊
The interesting experiments are really hard to do. I can imagine a test involving giving some audiophiles long term daily access to a very highly regarded system in an excellent listening room. The trick would be to change things out and see if they hear it. Change out a real copy of an amp or pre-amp or other component with a shell version that looks identical but has different innards. Have available a form to report if they hear something sounding off or degraded, or improved. They would never be told about the fake components being sneaked in on them. The point isn’t to put them on the spot, but to see if they notice changes when they aren’t expecting them at all. If it is found that they do notice changes on gear that supposedly measures well enough to be beyond the hearing limits of humans, then we have something interesting to start testing - just what is it that’s different about these components that allows people to hear the difference? If something is found, then that can be tested in future components and our understanding of how to make good sounding equipment will be advanced. Without some testing like this, all the reporting of improved sound without a meaningfully correlated measurement is just anecdotal accounts of subjective experience that give us little to build on. People perceive they are hearing differences I have no doubt. But they don’t know why although they offer conjecture. Perhaps the manufacturers do know why but if so they aren’t sharing information that would be very valuable to science and would dramatically enhance their reputations far beyond the audiophile world. As it stands I don’t see research in high end audio reproduction trickling advancements into other fields. That kind of substance doesn’t seem to be present. It’s always the other way around. Or am I wrong?
