The objectivist/subjectivist battle rages on in audio forums. Denial that subjectivist types hear what they think they hear etc. That the ear is not reliable in blind tests etc. That natural body and resonance are coloration etc.  
That an explicit, hyper-detailed sound must be right when long-term realisation shows that it is just tiring. If you want to show your system picks up a vocal inflection, a click of the tongue ''more betterer'' than your friend's system that's fair enough I suppose. The fact that it probably has a manipulated upturned frequency response to impress in a comparison audition... well never mind. When I look at Hi-Fi magazine reviews I am mainly looking out for the reviewer's description of something as 'musical'. That is what music is about not logic. Should not need to be said really...
I sometimes genuinely forget that I have loaned an item from my system such as a DC blocker and filter which would be hidden behind the equipment. I rack my brains thinking why is the soundstage relatively congested, where has the life gone. Then I remember I have loaned out this or that. Or when you audition something that should be better than what you had. You start by hearing what it does better. Then, maybe through tiredness, you just listen almost subconsciously, half-listening. The mind coming and going. Then you can judge if overall it is more musical and enjoyable than what you had before. In other words, when you are not looking for a difference and you hear one that is what counts! Call it subconscious comparison.
