Give a listen to Harmonic Technology (www.harmonictech.com)Truth-Link (copper) and Pro Silway MKII (2-copper, 2-silver conductor), and Goertz (www.alphacore.com) MicroPurl (silver conductors, copper ground) before making any final decisions. Some of the major problems when system matching are impedance and capacitance of interconnects. These designs hit extremely low values in each category--a major plus. HQ sells only through dealers. Goertz (Alpha-Core) has a 30-day no-cost approval program. Both designs, I have found, are excellent.
