I second that. Very detailed without having to be played at high volumes. I've heard the steps, the tempo III and the virgo - all great speakers. The only negative is that for them to get the spooky imaging thing to work, they have to be placed well into the room and be away from the sidewalls.
I love my Spendor S3/5's. I have them matched up with a pair of Sunfire True Jr. subs to fill out the bottom end, but at nearfield, I really only need one. At the same price for two Jr.'s, I could have gotten one Signature, and that's what I would recommend.
Swan M1. This little 2-way compact has an excellent ribbon tweeter and really makes the music sounds alive at low volume in a way most speakers can not compare. Not an expensive speaker and even available as a kit, it is surprisingly good.
