Well for me it is that sense the music is live and presents a feeling of solidity that seems to surround you like the difference of what you hear when you turn off your CD player in the car and walk into a club with a live band. Not a factor of the volume but more of a sensory thing. Even low volume settings can have that prescence. May have something to do with the mic and the quality of the PA except it happens with acoustic sound in certain acoustic settings.
