"Notice how Irvrobinson says all you need is a musician. A single musician? Talk about stacking the deck! Your system may sound "real" with a single musician softly playing a celesta, but can it handle a jazz big band or a full orchestra and choir?"
Of course not! We've already discussed this earlier in the thread. If the group of instruments won't fit your room, how could your audio system possibly make it sound real? Yes, a lot of systems can image beyond the walls of the room, but a facsimile of reality requires loudness, accurate loudness, and it can't be done in a small space. Or to put it in "you win" terms that Onhwy61 is looking for, I agree that an orchestra can't be reproduced in a small room in a way that can fool anyone it is real musicians.
