Own IC's. In my ears, they throw a "broad" soundstage which is very pleasant to listen to. Chashas1 is correct - Nearfield behaves much better. I've seen updates where the socks are removed, and a smaller ribbon tweeter is mounted on the top as well as repleacing the speakers with kevlar woven B&W parts. Offers you definition in the high/mid ranges. Do not exepect lots of base out of these. They need to be driven somewhat hard to sound good in my experience. To me, the best of its advantage is the "Broad" soundstage.
