Underrated
Ohm Walsh, Salk Soundscape 10 and 12 (out of production), JBL M2 (uses DSP and pro amps, but damn), legacy Focus SE, Spatial M3S Turbo
Overrated
Paradigm Persona's, B+W Diamond Series, McIntosh Speakers (though not sure anyone rates them highly), Focal Sopra 2,3
Disappointing - Anything by Zu
