Depends on your budget/taste, but I've owned the Ascend Acoustics CBM-170s for a couple of years. Not much to look at, but high content value and they reveal the soul as well as the detail of music. First used them for combined audio/HT, but have now have separate systems and the 170s are in the HT system for a variety of reasons. IMO their too good for HT. Are more musical than Paradigms, Dynaudio, B&W, the usually cast of characters at several times the price. The 170s are $330/pair. Efficiency is 89 dB/w/m. I use them with a Hsu VTF-2 that I also got from Ascend to add feel and a slight fill in. (Get extra bass due to use of wall mounts.) I love them and would highly recommend them in a $1,000 - 1,500 system.
I've also heard some of the Omega speakers. Even better than the Ascends, but only with tubes (I'm not a tube guy). Louis can do custom work for you and his cabinetry is wonderful. Prices run $400 - 1,400 for the different models. Efficiency ranges from 93 - 96 dB/w/m. Most folks/applications would want for a sub. I'm considering them for my new $3,000+ audio system.
