I still forget with my planar/ribbons, that they ARE in fact playing loudly, they just sound not as thinkly loud as the driver-based speakers I have owned. Took me a while, but now I recognize that tradional cone driver "thickness", as distortion.
The downside is if I set the volume too loud, like rock concert levels, with difficult 20th century orchestral recordings, they can break up with things like ffff timpani shots.
Those times when I want head-banger levels, I use my Tannoys or Cerwin Vegas. Otherwise I listen to undistorted sound at high but realistic levels on my planar ribbons.
