maybe if all clubs around the globe had a state of the art sound system we might notice the difference, but unfortunately most techno clubs are gonna find it hard to supply a system of the quality that would enable most of us to tell the difference. a lot of clubs still run a mono system, so again its got to be down to quality tunes. if the music really rocks the house, only fools will be complaining at the end of the night, because no matter what the medium is, its all about the music, and i think that maybe we should all bear that in mind.
