KEF Blade -- how good are they?

I liked what I heard from the Blades on two different occasions -
-blown away by their sound stage and sheer power over the room.
-did not care for their overall tone which was an odd mixture of warmth and coolness.  lots of midbass warmth yet at the expense of transparency.  upper midrange had a cool metallic after taste.  
-take care in amplifier partnering.  something like pass labs might work.
