When I think of "live" sound, I think of sound that's a bit forward through the midrange. More laid-back sounds less "live" to me although I wouldn't say it's a bad thing.
As far as having better sound at lower levels goes, this may be because the sound is more dynamically compressed, which brings the volume of the loudest and softest sounds closer together. This would actually be the opposite of how "live" uncompressed music would sound. You'd lose the contrast between loud and soft sounds so that when you turned the volume up to realistic "live" levels everything would sound relatively loud, which is not how it should be.
The more dynamic and uncompressed the sound is, the lower the apparent average level will be. Conversely, the more compressed and least dynamic sound seems to have a louder average level.
Compressed sound is very definitely more laid back... For example, most Home Theater receivers offer a dynamic range control circuit to compress the sound for late night listening. This is so the loud sounds like explosions and such are reduced in level and the soft sounds are made comparitively louder... so as not to knock you off the sofa or disturb the rest of the family. This also helps raise the intelligibility of low-level dialogue when listening at lower levels.
