I cannot help with the KS comparison but I just replaced a very nice sounding RSA poeimaii cables with a new set of GS Mk III speaker cables. The RSA cables retailed new about 5 years ago for $500 more than the GS Mk III. It is a bi-wire pair of silver ribbon conductors with the spade slot milled into the end of the conductor itself. The bass leg is significantly larger than the cable for the high frequencies. They are wonderful cables in my system and thought that they would be the last speaker cables I would ever need, but they were bested by the GS after a reasonable period of burn-in. They added a wee bit more structure and depth to the soundstage and the attack of strings as they are struck makes acoustic string instruments sound spooky-real on better recordings such as the vinyl version of Reference Recordings Kronos Quartet and on Yo Yo Ma's recent cd "Goat Rodeo."
I am in process of moving my system to a far better location with a new Steve Blinn Rack and lots of other goodies and plan to rrerun the RSA cables there, but I think the GS is probably going to stay.
