You are there vs. They are there

The two dumbest phrases in audiophile lingo. Meaningless. 

Not "They are there" but rather "You are there." 

"They are there" puts them at their venue, but puts you nowhere.

"You are there" puts you at their venue listening to their acoustics from a near, center seat.  In this case, I would think that you would want to deaden the room as much as is feasible because you don’t want to add any of your own sound.  

"They are here" puts them in your venue listening to your acoustics, obviously blended with their acoustics recorded into the media.  Room deadening is less of an issue because this is the character of the venue that they are playing in and provides more of a sense of "liveness."

She is here!  In fact, she brought the entire Blues Alley venue and audience with her to our home.
