I haven't heard any K-S product but found the Nirvana SX-Ltd disappointing in several different systems. It wasn't hard to find other alternatives that I preferred, in almost every case for substantially less money. I'm currently using Grover UR5 interconnects and UR speaker cable in my main system (Walker/Shelter/PhD, Herron VTSP-2, Yamamoto A-08, Avantgarde Duo 3.2). Good luck.
