There are those who believe if the “soundstage” is right, the timbre will automatically be a right as well.
Well, kind of. The trouble is I disagree with what "right" is. I mean, yes, sound stage and timbre is intimately linked, but those who like exaggerated sound stages also like a timber which is off neutral in absolute terms, and this is what has become the high-end bias. It's not better, it's just different but it sure does command higher prices.
