Bwguy,
I listened to the blade 2 metal again a few weeks ago and thought they lacked detail in the mids and highs. A consistent trend for me when I hear Kef speakers. Having owned B&W and listening to the latest 802D4 I would say the 802D4 is a lot more detail but has a much rougher frequency response. Both would be a pass for me, and I really wanted to like the kefs.
