Hi:
I own a Coherence II. It is incredibly quiet, which draws out elements of the music that are not audible with lesser equipment.
I also own Rowland Model 6 mono amps (with batteries), which you have not asked about, so excuse me for volunteering this information. The word that comes to mind is transparency. Very see-through.
No experience with the Simaudio equipment.
Good luck
