I've had Kimber Select interconnects in my system for a while - the KS 1021 (unshielded) and lately the KS 1120 (shielded). I like both of them, maybe the 1021 the most. They are obviously a high quality product, and worth auditioning.
Compared to my Nordost Blue Heaven, they give some more detail, but are a little leaner. The top end is maybe a little sweeter in the KS and transients are a little "slower", especially in the 1120. I'm going back to the Nordosts, as they are a better match in my system. Better value also.
I have not tried the KS speaker wires.
