Thanks, all.
The rest of my equipment is Bryston B60 (60W), Arcam CD 92, Rega Planar3/Dynavector DV-10X5. My curent listening room is ~13'W X 21'D X 9'H. I will definitely be moving within a year, so I am not tied to trying to match everything exactly to my current room.
My current speakers are Signet SL 280ex floorstanders, which until adding all of the above components, were the best part of my system the past 7 years. They have a nice sound overall, but a bit harsh (ex. vocals' "s"'s are grating at times), a lack of detail (as a sax player, for instance, love to hear that detailed reed reverberations and the clicking of these sax keys), and no where near the imaging I appreciate from B&W and Epos bookshelfs I've heard. While I realize moniters might be best for me, but my wife aethetically finds floorstanders more pleasing, and I am somewhat used to the oomph the Signets afford in rock and large orchesral works.
So in my online research, the arros seemed to be a good match as far as floorstanders that image like monitors.
What's leading me to consider the Sttaf's are the size of my room, the potential of added oomph/moving air, and the opinions that I've read that Arros are more finicky with power ... but don't want to lose too much of the imaging capabilites of the Arros.
Am open to other speaker suggestions (under $1,500 new/$1,000 used)- the Totems just seem to fit the bill from what I see(read), short of being able to compare speakers in the same room.
