Interconnect Recommendation

I just bought 6m balanced kimber Hero's for my main speakers, and 6m single ended kimber Hero for center. i'm finding them too shrilly in the high's. Anyone recommend anything else in the same price area that has tamer highs. i prefer warm sound, as my system is warm, but the Hero's did something that I just cannot explain, but hate. Associated gear. Main: Vandie 3a Sig, Audio Research D400MKII, AQ type 6 double run into HF, AQ CV4 double run into LF. Center: KEF 100, Classe CA100, AQ Indigo Gear: Pioneer Elite PD65 EAD Ovation Tributaries SCV100 dig. coax I had used the Trib SCA200 in shorter length before the Heros, and surprisingly was much more subdued than the Heros. I've had the Hero's for about a week, running them about 6 hours a day, and this weekend continuously.
