I Don't know if you gonna get the clarity you want from NAD. From what I've read it seems to be more 'smooth' hp. I think H6 would give you the clarity you want and it DOES HAVE BASS. This is from someone who comes from D7000 and LCD-3. It doesn't have over emphasized bass like D7000. The bass is there, it does not bleed into other frequencies and it is good quality IMO.
