The kc06 tend to be rather polite when it comes to highs. Yes, they have detail and is quite well done, but they lack the sparkle to present some genres to the fullest. I'd suggest something a little bassier but with more aggressive highs. Only one I can think of right now is the Bassos
i dont think the bassos have aggressive highs at all, i dont even consider the tenore aggressive
DN1000 on the other hand hit that mark.
