I might have some insight based on my own reactions to my own experience.
As a scientist (I am actually a scientist), I really hate the notion that I can hear the difference between interconnects and speakers cables, and it really PO's me that I can hear the difference with power cables.
There is no objective reason that I accept for power cables to make a difference, yet I can hear it. Cost does not seem to be a contributor, I have a pair of Blue Jeans Cables interconnects that I greatly prefer over a "nice" $500.00 pair, and the pair I am using now cost under $300.00.
Not all people deal well with this type of dissonance, and some of them lash out at others because of it.
I really appreciate the hard work that Alpha Audio has been doing. They are conducting the actual research that Amir at ASR only pretends to do. He is certainly not doing science, I am not sure he even knows what a scientist does.
In my mind, the issue is we just do not know how to measure a signal for its character. My field is like that, 20 years ago we did not have access to the tech to conduct the research I do on a daily basis today.
I suppose some folks really can't hear a difference, but I think most of the hostile ones do, and are angry about it.
