I feel I need to make something clear: The above is an educated guess on my part, not something established empirically through hours and hours of listening. However, on the one occasion I have listened to an indisputably top flight system - 808.2 into 8ks at HH2 - I could hear/feel the space around the instruments and voices in the live recordings demonstrated by Bob Stuart. However, this "air" was absent in the studio recordings demoed.

It's not a huge amount to go on, but I think I'm on the right track.
