IMO more people should listen to men like John Strohbeen, and Alan Shaw (Harbeth). If there's one thing I've learned over the years, it's all about getting the testing method down, then real comparisons can be made.
We hear about level matching all of the time, but it's true - our ears work in a very non-linear fashion. The ear responds very differently at different sound pressure levels. When making two or more comparisons, the levels have to be matched VERY closely...
But even more importantly, because most comparisons aren't even made at the same exact time, is the issue of audio memory. It's been proven that humans cannot remember what something sounds like (or looks like, for that matter) - after just a few seconds - it's just the way it is. VERY quick comparisons have to be made.
So when someone, anyone says they're hearing (perceiving) that something sounds differently - it's really hard for me trust judgement, unless the comparison had been made properly.
