Not quite.

Pity as that is what I use all the time when I listen to & enjoy my music system. Should I not do that? What happens when you do your "blind test" & it "proves" that there is no difference between A & B - does your ear/brain/vision system stop being fallible or when you go back to sighted listening of A & B you have to keep reminding yourself that the pretty, shiny one does not sound better? Or have you simply replaced one bias in this fallible system with another opposite bias? Chose your bias!! Teresa 1 Link to comment

I wouldn't argue that knuckle-headed responses don't happen here or that people aren't inconsistent in their willingness to follow advice. I just wouldn't generalize from that about "subjectivists" and their perceived inability to be rational, ie, to follow logic, to engage an argument consistently, to enter into meaningful discourse ---dialogue, discussion, conversation, dialectic, debate, terms which can be filled out and distinguished at least to some extent. But people seem to have very different notions of what these things are, and there are no ground rules that address how to discuss here. So we are not even on the same page regarding what it means to post in a thread, and what good practice is. This is a formula for the chaos that we experience. Sometimes I'm amazed that anything useful comes out of it. It happens almost in spite of itself. MikeyFresh 1 Link to comment

Sal writes with a sharp edge, but it's simply true that the ear/brain system is easy to fool. It's also true that sighted listening changes what we hear - that's well established. Obviously each person is free to evaluate sound however they want, but you can't claim accuracy/authority if you are basing everything on sighted evaluations using the ear/brain system. If that's my only tool for evaluation that is fine, but then I should also acknowledge the distinct possibility that I'm fooling myself at least some of the time. Part of the problem that in real life it's basically impossible for most of us to do any proper blind testing, so we muddle through as best we can without it. Some of us are comfortable with that reality, others find it very bothersome. Hey but in the end it's only audio. It shouldn't bother anyone else what I choose to listen to.

What happens when you do your "blind test" & it "proves" that there is no difference between A & B - does your ear/brain/vision system stop being fallible... Unfortunately, our brain will often continue to allow sight to override what is coming into our ears. We are creatures very oriented towards sight. You obviously can listen and enjoy how you like - and should. I think what Sal and some others are reacting to is using sighted listening as some sort of objective, authoritative yardstick. It isn't. Even for our own ears. We should at least acknowledge that. It's fine to say, "I like this better and that's what I'm listening to."; That isn't the same as saying, I added this to my system and I KNOW for a fact that it does x (reduces noise, lifts veils, firms up bass, etc)", because I heard it. A better approach would be "it sounds better to me, but I haven't tested it non-sighted, so I could be fooling myself."

It's also true that sighted listening changes what we hear - that's well established. firedog, not my intent to negate the value of blind testing, or the fact that the ear/brain system can be fooled (Isn't this less the case for trained listeners?). By going too far, I meant to take the caution about the ear/brain system so far as to negate the value of human listening, including the implication that average everyday listening and aesthetic appreciation are either radically subjective (to the point of near solipsism) or worse. To imply that there is something wrong with the listener? Perhaps the listener should be subject to a retraining program? Perhaps we can find psychological deficiencies as to why someone really dislikes the sound of a piece of gear (for me it was the Auralic Vega) that tests really well? Testing, including both measurement and blind testing, is not yet at the state that can guarantee preferences in sound quality. This combined testing is a growing, promising approach that has already yielded some fine results. But even Sean Olive has to exercise some caution in his claims, and woud recognize that nothing near adequate testing has been done yet. So I think Sal's sharp edge includes hypoerbole and overclaiming. Which is human, especially when someone feels passionate about something. But that passionate, rhetorical subjectivity often undermines the very objective message that one is trying to communicate. I find sharp edges fatiguing. Teresa and MikeyFresh 2 Link to comment

Nope, the correct phrase is "CAN change what we hear" but so can smell, mood, lighting, worry, tiredness, company - any number of things! What would you say is the best way to eliminate these influences on what we perceive? Teresa has found that over longer term listening the variations in each of these other biases may well cancel out - in other words her mood listening one day is likely to be different to her mood on another days listening, her tiredness one day, different to her tiredness another day & so on. Over long term listening, these factors will vary so much that what is the essence of the sound becomes apparent - the characteristic sound of the device, if you like. On the other hand, blind A/B testing focuses so much on eliminating just one bias sigthedness/knowledge that it ignores all the other biases/influences in how we perceive. It tends towards a one shot at "proving" what is audible. See the problem? Teresa 1 Link to comment

The problem is when audiophile only use sighted evaluation and make claims sound improvements brought about things like cables and other items that can't be supported by known mechanisms.

The mistake often made is to try to generalize this specific illusion to the statement "how much sight effects our auditory perception" What is generalisable is that all perceptions use whatever information is available to try to solve the particular puzzle that is perception. Why is perception a 'puzzle'? Because there is usually not enough information within the signal stream to come to one specific solution that matches the signals being received - there are many possible ways those signals could have been generated & the job of our perception is to select the most probable from all the possibles in double-quick time!! 4est and Teresa 2 Link to comment
