I am approaching 450 hours of "break-in" time and "liquid" is a very good way to describe the sound!
The Bass is just recently reaching levels above and beyond what I have experienced with any other speaker. Clear, tight and expressive, the decay from a plucked string is wonderful!
The Mids are in fact, liquid. Beautiful reproduction of the human voice.
And the Highs are stunning with every note clear and never smeared. Guitar pieces by the likes of Mike Bloomfield and Roy Buchanan show their genius.
I am very happy with the pairing.
