Audio Physics Virgo II's - Cabling


Just wondering what speaker cables folks have tried.
I have a set of these speakers ordered and am now in need of a new set of cables.

The rest of my system is:
Plinius 8200 mkII SS Integrated amp
Ridge Street MSE II Interconnects
Muse Model 9 CDP

Forgive me for not having much experience in the audio arena and asking silly questions, but should I aim for copper or silver cables?

I will probably need a 6-10ft run so wouldn't mind suggestions of cabling under the 250$ used mark.
I've used and been happy with Signal Cable in the past.

The best way to describe the DCCA cables is they
are unfatiguing, you can listen to music for
hours.
Thanks for the responses guys!
The DCCA's are nearly double the amount I have budgeted for speaker cables, so unless I can find a used set at a significant discount I won't be able to afford them.
Also a lot of the other suggestions (like cardas Neutrals...) are 300+.
Any recommendations <250$? or is Dimarzio the best way to go?
Another set to consider, if you can find them used is Straight Wire Maestro II. New they are @$300 less than the Cardas Neutral Reference. They are well made (except the spades are easily bent), but in my solid-state system were pretty neutral, clear, had very good resolution, and did nothing to call attention to themselves. I think I was able to hear more what the rest of my system was doing than any limitations or colorations of the cable.
