I think it is detailed and a bit open, as if showing you the ragged edges of transients, attack etc. However, the bass is solid and tight without being over-damped. I used a Rowland amp and Piega speakers and what I consider a very honest front end (Levinson/Naim). Levinson amps may be a bit laid back with overly deep soundstage and lots of air. Don't know about the Extrema but I think Satori may work well in your setup.
