@atmasphere "I always associated 'air' with ease and space in the highs. I've not heard of it used in the context that you do; probably a topic for another thread. "
Pretend yo are in the Berliner Philharmonic concert hall....you listen to a big orchestra playing very powerful music, the volume is high but never compressed, it is just floating around (not only the highs). No speakers in this world can do that but our ears together with our brain can let us imagine that we are there when we listen at home. Nice....
Well, I do like the sound of my 89dB speakers so they stay for now.
