As I've never even remotely made such claims about myself, I'll chalk this up to 'delusion'. Or maybe hysteria.
On the other hand, the assumption that 'I hear a difference, therefore it is real' is rampant among audiophiles. For a fact, science rejects that assumption, with good reason. Your problem is with science and human psychology, not me.
I'm here by accident; I was curious of the latest post of this thread by Arnold K. (last post from the previous page).
I then took some time to revisit some, including the very first post, and few more. Your last one just appeared now while I was busy reading, plus replying to an old post from Kal, with a touch of humor.
When hesitating between which and which should I pick, the one as the best sounding component, follow your instinct, your comfort zone.

Now in reply to your post above; I'm sure you never made such a claim, ...I was replying as to it sounds like, not to true reality.
Forget about delusion or hysteria; it has nothing to do with you or I or them, us all here in this thread. Trust me on that.
Your second paragraph, now that is interesting.
It is to me a valid infinity. It works perfectly with one within the universe.
If I am a witness of the same listening event, meaning I'm there too in the room and sharing my own thoughts on what I hear, I too bring another brick in the wall, meaning a variable, differing or agreeing opinion.
Without being there I cannot bring the entity here. Meaning there is no assumption, nothing, no perception, no anticipation, no presumption, no confirmation, no nothing. I cannot even agree or disagree with the unknown.
What is science? I'm serious. How do we compare science if not by equations through time. How changes affect science. How do we interpret our analysis of theorical measurements with other's own set of measurements in a comparative normal equilibrium. Are measurements incomplete hyperbole without comparing them with other values.
I just don't know in audio, I'm here in the search to find out what I can look for.
