To me the "advantage" uyou describe the N805 having is really just a feature. Plenty of higher quality speakers have not bought into the concept of a two wirign posts available for biwiring. I have heard the Revel M-20 extensively and the N805 (non-sig) briefly. I saw only broefly becasue I was immediately nto a fan of the sound. Far too forward and hyper detailed. If you are into that then it is the better than the . However for the overall speaker I thought the M20 was in a different league. the N805 is one of my favorite B&W's but I didn't liek what it was doing in the room with Krell electronics (ap ossible culprit unto itself). I woudl go with the M20: more neutral, natural, and accurate, and musical. Also please look at:
Dynaudio 1.3 mk II or 1.3se (speakers i bought btw)
Merlin TSM (similair to the Dyns)
sonus Faber Signum (warmer than above)
Silverline Sr-17 (great price used, a richer Tsm sound, wonderful soundstaging0
Of course try to listen in yoru own home, these are all small speakers and can/shoudl be auditioned in your enviornment
