Which purist interconnect??

Hi, My related equipment is Music Reference RM9 MKll,
Audio Research sp9 mklll with GNSC ref. mod and Aethetix
Rhea with GNSC ref. mod. So I need two sets of interconnects. I am currently using Cardas Golden Ref.
My budget is not unlimited, perhaps in the range of the Cardas Cable.
Thanks
Richard
