Well... if the HE-6 came as a 'closed' model, with the same sound... and easier to drive, I'd snap it up in a minute.
I prefer it to the LCD-2, HD-800 (which are very good), T1, and others.
I really did not like the LCD-2. Aside from being ridiculously uncomfortable, I found them dull.
But the HE-6 has a near perfect sound to my ears.
So... the next best thing to that, in a closed can... the D7000. I couldn't live without them. I have them on my head every day, and just love the sound.
They are my second to the HE-6.
Apparently the weight and darkness are quite a deal breaker for some. Maybe I'm sill young because I find myself really really sensitive to bright highs. I just can't stand a single bit of brightness thus dark cans are just right for me, making me worry the d7ks might not be for me. That said, were u trying the rev 1 or rev 2. I heard the rev 1 is darker, I'm not sure because I tried the rev 2 and they were pretty close to perfect for me.
