Those are probably the best 2 headphones for my tastes that I've ever heard, though I've only heard them at CanJam.
Very different animals I think, especially one being planar & one dynamic. The Empyrean is on the warmer side, but there aren't many peaks & valleys in the F/R I think (except maybe the velour pads boosting somewhere in the treble). It comes across as smooth to my ears, but no lacking in detail retrieval, which is a fine trick.
The Verite is more 'alive' sounding to me...similar in a warmish tone(downward sloping F/R?Edit: at least downward after the mids, which are slightly elevated to my ears), but they sound very different. Not a relaxing listen, I guess the transients are more sharply defined, but not sharp...not fatigue as far as I can tell, but it was show conditions.
I hope that helps a little...
I'd have a very hard time picking between the 2 if money was no object.
