Pmboyd, I have tried this far 3 deliberately shielded or filtered wires on amps: Cardas Golden Ref (slightly warm with some stray intermodulation in the treble and gentle rise in the mid-lower bass), Shunyata Anaconda VX (removes very low level detail and has some intermodulation in treble), Purist Anniversary (slight rise and unspecificity in bass and not most extended in treble). I tend to prefer moderately or no-shield PCs like the already mentioned Shunyata CX KC, the somewhat shielded Furutech Evolution II, and the equally moderately shielded Furutech Hi Performance (bulk) series wires. They tend to be more open and paradoxically exhibit less artifacts in my system. On the other hand, one man's artifacts are another man's (or woman's) grails. . . thus my general caveats. G.
