It sounds highly detailed on thd leading edge ,that being said after longer listens
the naturalness and valance is nowhere near as good as the AQ Sky ,and for a slightly warmer balance the Colorado. Myself and others that have very $$ top notch systems as well as listenjng to live venues I totally agree with the purer the metal the more even balanced as well as electrically correct which is very musical. you would be surprised that at least 6 of your top U.S made dabbles use
Solo crystal, or AQ hoes one step further and I believe micro Polish the surface
