Here's a reasonably priced very high quality source of cables.
http://www.signalcable.com/. The owner is a pleasure to work with. Marty DeWulf at Bound for Sound is very high on the Signal Cable interconnects speaker wires and power cords. I use the interconnects and speaker wire.
This flame should hopefully be ending soon but I'll add a little more fuel to the fire. Those that say "wire can not make a difference" simply do not have a system that is capable of resolving the difference.
Or, in other words, if you substitute for the source in a $499 HT in a box system a top of the line Wadia CD player, will you hear a difference? Of course not, end of argument.

PS- a good portion of the members of the audio club I'm a member of have Omega Micro cables (the distributor is a member of our club); believe me, you can hear a difference.
