what's best cables for this system ??

I would consider either Bear Labs Silver Lighting interconnects, and/or Granite Labs #470 Silver Interconnect. If you think silver will be to forward sounding consider the cardas Gold Reference interconnect. Presently I like the Silver Audio Symphony 48 speaker cables.

Check out Homegrown Audio on the maufacturers link. Silver at good prices.

What Ljgj says is true. For their price they are hard to beat,but I don't think they can compete with the Bear or Granite which cost more$$. The Homegrown Audio new speaker cables are a killer!

YES I FORGOT TO MENTION THE PRE-AMP,IT`S A ARC-SP9 WITH PHONO.THANKS FOR ALL REPLYS.
