Interconnects recommendation for passive preamp?

I am currently using a Reference Line Preeminence One A passive linestage. The manual strongly suggests the use of low impedance, low Q interconnects. Any passive users out there with suggestions? I am considering DH Labs Air Matrix which one dealer highly rcommended. I can use .5 meter pairs which should help keep the capacitance down. The problem with most cable manufacturers websites is that they don't (with very few exceptions) list the "specs" for their products. HELP!!!
