IC's of that length are fine, but please do pay attention to the post by Al regarding cable shielding and capacitance. You need a cable that is designed to handle that length of run. Please note that if you have an sources of nearby electromagnetic noise (AC wiring for example), a coaxial style interconnect will not be a good choice. You need a cable with ability to reject electromagnetic and electrostatic noise.
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.
