Well got my kefs up and running, so far so good. Quick blast of a bluray and a few games on the 360 and i'm impressed. I've gone from a samsung all in one box jobby and the difference is very noticable (new amp aswell though).
I understand what is meant by neutral I think thats a good description, I dont think you'll be disapointed! They are very clear and clinical, reloading a gun for instance on the 360 is incredibly clear.
They look great too, wasn't too taken by them in the shop but up I think they look good, and a bonus that they have mounts which rotate (very slightly) giving you a bit of an angle if you dont want them facing straight.
Took some photos for you, the one of the sub aint great but its very nice and sleek.
HTH Cheers
