For me, a switch was different. “What the hell’s going on here” different. I’ve spent er gosh 4 decades in IT/digital and that might have fed my pre-experiment cynicism. But I do humility too.
I've picked this up late, so may have missed things, but....
My curosity is perhaps focussed vai the comments you made about this not being a "belief" earlier. I haven't read/seen all the details of the test setup, etc, that you did. But the "belief" may be a matter of having heard a genuine 'difference' and then assigning it to something other than the actual cause. To know, we'd need to know more about all the details that may have had an effect which you then concluded were specifally due to the 'switch' itself which you concluded is 'better'.
The reason people do double-blind, make as much as the rest of the setup "common mode" and repeat check, perhaps even use a head-clamp, etc, is to reduce the chance of such problems. Otherwise easy to mis-attribute the cause of an audible change. So may be reasonable to doubt 'surprising' reports.
