It would help to know what you're currently using and what types of sound characteristics you're looking to preserve or improve. Also, you don't mention any power conditioning or dedicated lines?
Morrow and My Audio Cables(MAC) seem to get consistently good reviews (along with may others listed above) although it always comes down to individual tastes and system synergy of course. At least they make it easy to try them. As for PCs, I haven't tried them yet but Triode Wire Labs seems very interesting. And I read a nice review of Luminous Audio power cables a while back (Positive Feedback I think) that always stuck in my mind. Best of luck.
