I've now owned my M3's since April. Over that period, listening about 2 hours/day, the speakers have definitely "opened up." In particular. the much hoped for "holographic imaging" has significantly improved to the point where some CD's are simply remarkable, i.e., Bill Charlap "All Through The Night" and much other jazz (my primary genre). I also agree that new, upper frequencies did sound a bit rough. But now music truly "blooms" into the room and is simply ravishing. The bass is wholly satisfying in terms of presence, pitch, and texture. I was at a "dinner party" (yeah, I know it dates me) the other night and the hosts owned a music system which they lauded but which, to me, were agnostic to musical values (at best). They asked me what I thought and I asked if I could be honest with them ("yes"). I discussed soundstage (absent), dynamics (boring), and the lack of resolution/detail that make music exciting. They asked if they could listen to my system. I agreed and we decamped to my house (down the street). I sat them on the couch and fired up the Psvane 845 monos. Then I played Ted Nash, Art Tatum, Chris Cheek, etc. They sat on the couch stunned at the presentation. Then they asked me to help them achieve that experience in their home. I credit the M3's to a huge degree. Yeah the ancillary equipment is quality stuff but the M3's provide. If you're not getting similar results check and re-check your room set-up because these speaks seem limited only by the room and ancillary electronics (at least with the music I listen to). BTW, I'm using the 4 ohm taps on the amps.
