my computer speakers have nuff bass trust me - got one of those jellyfish-glass floor level sub-woofer jobs
ramadanman is great
a more serious point, though:
i've noticed that people have absolutely no problem with people offering comments when they're based in Australia, or other remote-from-the-scene locations, when those comments are positive
no problem at all with positive comments that are based on YouTubes, soundcloud clips, MP3s of dj sets
BUT when it's negative comments, then people will draw for "you have to be there", "you can only judge if you've heard it in the club, through a big system" counter, to discredit the argument...
which is a tad inconsistent !
anyway I concur with Man Like Ory: if you've got 20-plus years of going to clubs under your belt, it leaves you with a pretty sharp sense of how a track would impact through a big system
