Now I know why a dog chases its tail; they just can't help it.So how do we know what is a bug or what is too much (cold pressed) coffee (slammed down of course), some sort of ear fatigue or confirmation bias? The whole premise of objective facts could possibly only happen if we had recordings released by FAS of what each amp sounds like. Even then different guitars, rooms, playing styles etc. would bring in subjectivity. Till then I would personally have people let them know what they are hearing and let FAS decide what to do with the feedback.
Reread the last sentence of my comment. "Having a recording showing the difference(s) would save a lot of back and forth discussions trying to determine if something did in fact change." Posting a recording demonstrating a change in the sound provides objective proof that there is a difference. We're not discussing accuracy between what FAS designed the amp to sound like and what we hear. We're discussing the difference we hear in an amp model from one beta to the next.
If you make a comparison recording and it shows an objective difference, FAS can then investigate to see what caused the change rather than spend time in discussions. If the recording does not reveal a difference, then we can chalk it up to our ears playing tricks on us. Taking a bit of time on our end saves FAS time on their end determining if in fact there is a change that warrants a deeper look at a model or feature.
Suggesting that we continue to make claims of something changing without evidence and let FAS determine which claims to pursue is not really an ideal way to perform a test.
