I'll post some more thorough impressions once I've had the chance to listen to them...but right out of the box, I'm impressed with their balance - bass doesn't seem to hit as deeply or viscerally as either the Nio (w/m20) or Solaris 2020, but there's zero bleed into the mids (which I get with the Neo), and the treble is bright, very well articulated, clear, and crisp. Stage is very wide and enveloping.
I'll sell my Nio's (I was leaning that way anyway), and prob keep my Solaris 2020's as a "balanced hybrid" alternative.
1) pretty amazing for $1349!
2) since I tend to prefer bassier/warmer tonalities, this will be a perfect match to the LX SE. the bass on the Hero is very present - not overwhelming at all, and very well controlled (not sure if burn-in will change this)
