Yeah, soundstaging is like a kind of 'peak experience'.
Once you have experienced it, you KNOW what it is.
Everybody else can 'talk' about it, but they are only spouting 'words as theory'...
For myself I like dipoles best.
Then the musical presentation has to have the 'air' around the performance there or it is just flat anyway.
"air' is another word with a nebulous connotation.
