16 feet is not that long and any good quality shielded cable will do the job. If your components are truly balanced then balanced cables are the way to go though I doubt you will here any difference between single-ended and balanced, with single-ended components, at 16 feet.
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.
