Looking for a Shotgun...

Hey folks - looking to upgrade my biwired Nordost Red Dawn Rev1 with a pair of true shotgun cables (I have a multichannel EAD PowerMaster 2000). I know about the ZuWax and the Acoustic Zen Satori, but what other cables are available in a true shotgun configuration (essentially double wires). I'm looking for something on the neutral side.

System: EAD PowerMaster 2000, Revel Studios. Budget: Used for under $1000.

TIA!
