@Cantrell:
A quick jaunt with my PC out (@77 ohms) didn't really scream any huge changes at me (well once I fixed the grounding problem, but that's nothing new for mic'd cables at times) so I wouldn't tend to think cables make a huge difference for them, but YMMV of course. The stock cable is obnoxiously stiff though - to the point where it's only saved and made usable by having a chin slider.
I will say that I really had a tough time noticing much in the way of differences on the first day of tip rolling, and really had to push the volume up a little more than I'm happy with to hear differences clearly enough for something to stand out as better for me.
Listening with some large chifoams T400 size inserted to a borderline uncomfortable depth (about the same fit I remember getting from real Comply) and I can certainly hear some stuff that borders on almost sibilant at times. I'll try some work from the artists you mentioned a bit later and see how they treat me.
In my many years working with guitars (a much much lower signal level I think) internal wiring, guitar to FX pedals or amp, FX loop cables and much higher output Amp to Cab and internal cab wiring I've had fairly big differences with changing of aspects of cables and solder.
I'll wait n see what happens with break in on mine and what exp you get listening to those artists for now. If nothing else I'll try buying or building a cable with unplated Copper, Tin Plated Copper or cable mixed of either of those and silver plated Copper to see if it reduces or eliminates the problem if break in and tip rolling doesn't.
