Ah..Pgulrich, before you claim the JMLabs with Be tweeters are the "most transparent speakers around", have you heard the various current electrostats (SoundLabs, Audiostatic, Innersound etc), ribbon speakers (Apogee Synergy, Analysis Audio), and horns (Acapella with the plasma tweeter, Avant garde)? I've heard most of these speakers, and transparency is not one of the standout features of JMLabs (Grand Utopia Be) in comparison.
