Cables for Theta Processor/Amp??

I am currently upgrading my Casablanca I to a III. Additionally I am thinking about getting a Dreadnaught II amp. I am current using Straightwire Maestros pretty much all around. Since I am spending big bucks, why not up grade some cables too. At first I figured digital connections, power cords, interconnects, speakrs. Other components are Accurus 200X3 amps, Aerial 7B/CC3/SR3, Sony hi-def direct tv box, 9000Es DVD player.
Anyone using a Theta front end? Any recommends?
