I recently put some soft leather pads on the HE-6 and it's like I superimposed the bass of the LCD-2. Who ever heard of a U-shaped ortho?
I think Brian Reimer Audio had an HD800 for audition at some point. You could give Steve (sckeith) a shout if you want to try out the K702 again.
I'm still trying to figure out what path to go if/when I downgrade.
