I've removed the last few posts, sorry, I really don't like doing so, but pig headed reasoning and personal attacks don't bring much to the table.
the problem @groovyd is that you keep talking as if there was only one way, disregard all the possible options, how plenty of variables totally affect the values and behavior of the phase shift, and how the human ear reacts differently to all of the above. including the most obvious matter of threshold that you decide to forget just to make an overly simplistic statement. if a claim has plenty of exceptions, then it's a false claim. it doesn't matter that it's true under a few given circumstances if you don't explain what those are and instead keep making general hand waving claims.
I'll take this one:
1) is true, there are plenty of ways that phase will be affected and it would be nice to explain it, but overall, that is true.
2) is also true, but more like when I say people can easily die from drinking water, kind of truth. they the can drink 15 liters per day and ruin some organs, they could fall on the glass and cut themselves. they could drink contaminated water and get poisoned of sick. so it's "easy" to die from drinking water. you can say it, but don't pretend to be surprised when people show up with counter examples(including the paper mentioned above) where humans have in fact a hard time noticing certain phase shifts unless they are past a given threshold.
3) is an empty claim not an argument in favor of anything. I have no doubt that you can manufacture a phase shift you can ear, even I can do that, or there is a nice example in one of the proQ tutos on utube( those vids are great stuff to understand the basic of EQ IMO). but that's different from proving that it's easy to hear the phase shift from proper use of EQ in music(from all kinds of EQ).
add conditions to your statements, or stop making them, those are the 2 ways for you to really tell the truth.
