Just my Opinion dear friends,but with Focal La Scala,between Burmester and Pass,there are many different.If you like high details,speed and huge control ( too much for me ),go a head with Burmester.If you prefer Airness,Musicality,Fullness in Harmonics,move to Pass Labs.I I had Burmester and Spectral in the past and few months ago I move to Pass Labs for this reasons.I don’t care HIFI suond,but I prefer Human suond ( as we are ! )
