Long IC Cable Run

Hi, I'm in the process of sorting out a new room in a new house. The configuration I'm shooting for requires running 16 feet of cable from my preamp to amp, and I'm wondering if an unbalanced RCA type configuration will be ok considering the long length? Otherwise, can my components be modified and made balanced (they are all unbalanced)? My system consists of a Rogue 99 Magnum preamp, Threshold S300 amp, and Arcam cd36 player. My speaker cables are Synergistic Designer Reference, power cables are VH Audio flavor 4, and no interconnects yet . . . Thanks.
