>>>>I disagree. The weather, time of day, and things you might have done to your system either on purpose or accidentally as well as other variables must be accounted for. There is also break in and warm up to consider. It is certainly not black and white as you suggest.
What I meant is if you could hold or control all the variables except the human one, there could be a noticeable change from one day to the next. Sorry, if I was not more clear.
But If you know in your own mind it really works, then there is nothing to argue about.
But generalizations like ’most’ and ’thousands of people’ means nothing to me without empirical evidence. If highly regarded artists as well as audio and recording engineers were also to support it, I would certainly consider it more seriously.
There are scientific studies done that prove differences between reality and perception. It is not philosophical.
