preferred interconnect for FM tuner

I have an AMC T7a tuner and am looking for a compatible interconnect. I am currently using AudioQuest Diamondback RCAs and not finding the AQ's intense focus and brutal honesty a good match with the AMC's strengths - smooth sound and good soundstaging, but a bit noisy, at least where I live. Think I need a warmer and more forgiving cable for this application. Had some older Chord ICs I liked, but those are gone. Ideas?
