If you are considering the Nordost try to demo the Nordost hiemdalls if they are in your budget. I have a nordost demo case right now and I find the blue haven to be a little on the bright side compared to the hiemdalls and freys. As you move up the nordost line the little more brightness goes away and more 'air' is between the vocals and instruments in my opinion. I personally think that the hiemdalls are pretty much at the point of diminishing returns (although I just bought the freys) for a tad more 'air'. You have to consider just how much you can afford for the sound you are looking for.
Also I think for the money the AQ line is the most reasonable for its price points but just not my cup of tea for long term listening (JUST MY OPINION and do have a pair of the King Cobras on my dvd player).
