Well there's the phatness in percussion and leads especially from SA producers. I can easily tell when a track has been made by a SA artist.

I was just kidding Of course it's a matter of taste.
Like I said if there's one thing that shows the talent behind the SA scene is teh fact that hasn't lost its quality. SA started in 2002 with almost minimal, dark techno beats, it slowly became more melodic snd really fat, then even more morning with less phat-until-you're-deaf sounds, then kinda more dark again etc.
We're talking for 9 whole years! I can't think any other psy subgenre that kept that long without losing its quality for some period.
