You won't be disappointed by the speakers. Also the Kube 2 sub is top notch. A driver unit failed on my sub though about 2 months before I sold them. Kef replaced with a brand new unit no questions asked. Superb customer service.
Looks like I will be trying out Kefs wireless option for the rear speakers when I get some. Should be interesting.
What speaker cable did you get? Decent cable = better sound, I always get mid priced stuff.
