I think with hi-fi, there's three tiers when it comes to 'improvements' - calculable, measurable and noticeable.
Magazines (and forums) will wank themselves demented over things that are calculable or measurable but it's only when something becomes noticeable that it's important and then, because it's so subjective, with so many variables it's really down to the individual to decide if they like it or it's 'better' for them.

tl;dr?
Most of it's bollocks.
