I agree that some hard techno has got a little generic, but top producers such as Skoog, Wilson, The Anxious, Klein and Rodell have kept things more than interesting for me personally. The devastating Wittekind/Laker sound still does it for me too i have to confess, love those hammer beats...

OK, so you may have to sift through more records these days before you find somin that's gonna go straight in the box, but when you do come across those records, i find it more rewarding having had to search a little harder...

Plus, it's like Mark says, there are more specific genres of hard techno than ever before right now, so it stands to reason that certain sounds are gonna become slightly dilute...
