I haven't heard any electrostats in a 'normal' environment - 8'-10" ceilings and near a wall.

I think the environment in which the Martin Logans were playing would be very challenging for conventional speakers.

There was nothing flat about the MLs firing into that large space. When they cranked the volume to levels far higher than the material which was recorded, they did get a bit bright ... shrill actually. However at normal listening levels they reproduced music in a spectacularly realistic manner.

Enjoy the Music. Trust your ears. Laugh at Folks Who Claim to Know it All.
