I'll post more, but for the time being, think perhaps of an LCD-2or 2C, but less thick, a bit more airy and lighter, which also means the lower bass is more lightweight as well. Still a tendency to warmth but not thickness. A smaller footprint if you will. There is a suckout in the upper mid/lower treble (common with planars) which tends to make things sound a bit dry in that area, but also allows a smooth bass/lower mid/midrange and less danger of painful sibilants. The downside is that cymbals and other high frequency information can sound somewhat muted. See, transferring what I hear into sentences is not always easy..
