Mark's ongoing bitterness notwithstanding, this is an interesting question.
Do "listening rooms" - i.e. spaces designed for enjoying reproduced/recorded music share the same desirable design traits as concert halls (intended for live music performance)?
I would think that the answer is "yes". But I want to test that assumption.
I hope my lack of a smiley didn't throw you off my jesting nature!
My thoughts are this:
If a recording is made "live" and they are mixing in the ambiance of the hall, then you're kind of doubling up" on the ambiance if you listen to the playback in a hall-like room.
If, on the other hand, a recording is dry... lack of ambiance and no added reverb or room tone, then a recording will sound "dead" unless you add it electronically or listen in a hall-like room.
Finally, though, if you ARE adding ambiance electronically (surround channels) then you're back to wanting to listen in a non-hall-like room since you're adding that effect.
