Well lets say it another way. They ring very subtly in a very narrow band. You can move your head and you get within the 'safe range' in and out.I've got a pair of kh150s which are supposed to sound likewise. Harsh is really not how I'd call them. They got the best mids and highs i've ever heard, absolute clarity.
It feels like you are going in and out of phase. That really matters for me as I play the Piano and I want to feel like I am playing the Piano, and not listening somebody play it.
Same for the Genelecs I tried.
