The HE-400 should be in at any moment.... GAH, the wait! That and my KSC75 to steal the clips off for use with my KSC35.
Edit: Got them in. Why in the hell did I EVER sell these? Dear sweet Jesus, how I missed that holographic sound.
These are considerably more clampy than the last ones I had. Better remedy this tonight.
I think the "holographic sound" is one of the he-400's most outstanding attributes--that and the amazing sub-bass. It's strange though. The he-500's sub-bass and imaging are almost identical to the He-400's (at least tons of A/B comparisons suggest this.) But the he-400's voicing (read "upper mid-range recession') discourages me from ever dwelling on the mid-range, and encourages instead a more bass-centric focus--while exactly the opposite is true of the the he-500. Mysteriously enough, the He-400's voicing also seems to accentuate its holographic imaging. I'm not sure why this might be, but to my ears, the he-400 has a notably more holographic presentation. They are keepers for sure!
