But when it comes to amplifiers, ASR rarely listens, with the general justification that magnitude of differences are too small to differentiate (with some exceptions). As you can see in this thread all listening (that isn’t done by ASR with partial protocols) is routinely dismissed as sighted bias, expectation bias, focus bias etc (you too can play bias Whac-A-Mole).
The pushback like that is made when the claimed sighted tests go counter to solid body of engineering and research. Say a power cable improves the sound because you swapped one for the other and proof of being right is "I have been an audiophile for 30 years" and you rightly get strong pushback. Don't offer such as proof point and you are generally fine. And even if folks object, you should be cool because you weren't going to prove anything.
How else do you want us to behave? I once asked my doctor if he could help me with research into weaknesses of blind testing. He just about threw me out of his office! He said, "Amir, the foundation of what I do is based on blind testing; I can't participate in any attempt to cast doubt on it." It wasn't my intent to cast doubt but I fully understood his position and continue to see him.
Before funding ASR, I was the co-founder of Whatsbestforum (WBF). We thought by allowing both camps to state their position, life would be good. Well, it turned out to be anything but. The conflict eventually crept between me and my partner and I sold out my shares and got out. I decided then to go the "pure" route and start ASR. The name clearly states that we are committed to teachings of audio research and engineering for decades. We don't pretend to be smart enough to invent our own rules of universe for audio and champion that to everybody else with vengeance as folks are doing here.
Net, net the response you mentioned is what you should expect if you come and make outlandish claims. You have seen me respond similarly here. As I said, it is a jazz club and you shouldn't expect folks to take kindly to you demanding that you play country music.
You want to come and challenge our position? Do so with solid research and science driven listening tests. Be ready to defend yourself and not cry victim with "oh they ask for controlled test and tell me about bias." Of course we do.
Indeed, many people who have a short life in ASR mistakenly assume they are stating something new to us that we are just going to roll over and accept. Member @kota1 for example shows up and says every cable needs to be broken in for 100 hours or the test is invalid. We have heard these claims a million times. Don't be the million and one member who thinks you should just throw that at us and we go, "oh, I didn't know that; thank you for that information!"
Read the forum a bit and get educated on what and who we are. Then participate if you need to. You are welcome to challenge us on every topic. Members do that to me all the time. But be ready for heaven's sake with some back up worth more than a fortune cookie paper!
