Since you already own the Alpha-Core Goertz speaker cables, you know their product line. I suggest you seriously consider their Triode Quartz 2 (TQ2) interconnects, which have a MSRP of $186 per 1-meter pair. The original TQ1 was developed specifically for use with tubed equipment, and proved very successful. I recently installed the newer TQ2 IC's from the phono preamp to the main preamp, and from the preamp and power amp, and have been VERY pleased with the results (the TQ2's replaced HomeGrownAudio Silver Lace IC's). The October 2001 issue of Stereophile contained a full review of the TQ2 and other Alpha-Core interconnects.
