Precision, I do not own these speakers. But I was given several opportunities to listen and appreciate the amazing quality.
The first time I was put in contact with these two monsters electrostatic panels technology was there fifteen years in an audiophile equipment dealer. Asking what I would, in addition to listening to music, hear the music, he put me in front of two panels and then the slap, emotion and more!
Better than play music with perfect precision (registration required quality) require a presence, absolute relief! The orchestra musicians take the body in space. Strings are before the woodwinds, brass behind. Incredible! 3D before 3D! The enclosure completely disappears to let the instrument occupy its space, all space and live.
Reproduced from experience in totally different conditions, domestic, with other ML too, but still the same quality, the same rendering and reality of space that leaves me speechless every time.
