dali helicon 300 opinion
Just listened to these on the way home tonight. They compare very favorably to the B&M 805 signature. They have the same openness and depth with a different midrange and mid-bass character. A bit on the brite side.. but they seem to be less nasal than the B&Ws. Acoustic bass plucks sounded much cleaner and less hollow. Anyone else audition these ? I also like the dynaudio S1.4 but have not done a side-by-side.
