I have had a pair for about a month (white). They are driven by AR REF 3, Ref CD7 and AR Ref 110 stereo amp. I thought I would buy a pair just for fun and probably sell them quickly. After hearing them, it will be a long time before I make another change. They are the most accurate and natural sounding speaker I have ever heard. I am in the business, so I have heard a lot. There is almost no coloration from the lower mids on up. The blend between the tweeter and mid is seamless. They have a lot of detail, but sound buttery smooth at the same time (the AR gear helps I am sure). There are more powerful and dynamic speakers out there, but for listening at moderate levels in a medium size room they are among, if not the best in the world.
