Hi, I am shopping for some decent quality cables for my new speakers. If I buy cable by the foot (unterminated), the price is like half of what it is if I buy it terminated in preset lengths. A few questions: 1. Is it worth it to buy them factory terminated? 2. Is it difficult to terminate it yourself, and should I except better sound quality if it is "professionally" done? 3. Are there any advantages to an "internal" bi-wire configuration (for speakers setup to biwire) as opposed to just going doing it full range? Here I am referring to using a single cable and splitting it to bi-wire at the speaker end, not actually doubling up on the cable. I ask, because a vender told me that there is no benefit to bi-wiring unless you actually double up the cable. He said save your money and just have it terminated normally, or else go the whole 9 yards.
