@hartf36 The difference could be that I moved an armchair from one corner of my listening room to another, and it completely changed the room acoustics, all else being equal. Does that count?
Yes. The all else being equal being the the objective measurements of the equipment. It is data. It can be banged with a hammer and it will not change.
Then game-on for individual preferences, circumstances (however defined), room arrangements, and exaggeration.
I understand. Indignation. I use that word with some trepidation as I tip-toe away into a safe zone. .
