Tone arm wire: looking to upgrade

Any suggestions on what is a good wire, I wouldn't want to put in a wire that is marginally better. What would be considered better or best in terms of revealing micro-detail and holographic imaging? And where do I find these rewire kits? Would like to hear of a couple of options in descending order of what is best. thanks I own a vpi tnt with clearaudio satisfy arm and grado which is being upgraded to sumiko blackbird.
