+1 BJ cables have been mentioned several times. If you want to save money (about 50%) and enjoy some DIY, here’s what you need:
Choose Belden 5T00UP (as used by BJ), primarily because it has the lowest DCR (0.001 ohm/ft). Ideally, you want the resistance to be 0.01 ohm or less, so a 10-foot speaker cable made of 5T00UP is right at that threshold. Also, it gets one of the lowest capacitance (26 pF/ft) preferred for optimal sound fidelity among the cables in the market. Pair it with Nakamichi plugs, and you’ll have a high-quality set of speaker cables for around $60 / pair.
The result sounds excellent—comparable to the solid copper AudioQuest cables I’ve owned for 25 years.
