I've heard them the last 2 years @ CES in their (Linn's) suite. Both 5-channel configuration and 2-channel setup, with the smaller and larger versions of the speakers including the stand-mount ones. It was VERY nice. Active is the way to go, as with all things LINN. The fit and finish on them is immaculate. If you can afford them, they have few equals, really.
