There's not much to audio interconnects, and just about any sort of cable with RCA's at the end will do the job of sending the signal from Point A to Point B with no audible degradation. Consider the following
link that discusses interconnects as they apply to preamps and amps.
Apart from differences in cable diameter and minor differences in resistance, capacitance or inductance, there's no audible reason to prefer one over another. They all do the job. Some have greater shielding for those who have a unique situation with EMI/RFI. Hand made, as with anything that is hand made, will be more expensive. Someone's got to pay for the labor and that someone is you. Moving up in the price chain gets you better (different) appearance and the ability to say I can pay more for something that doesn't have to cost more. So Monster, Radio Shack, various Beldens or Canare, AR's, generic material such as
these from National-Tech ($6 for a 6ft length of 3 cables) will all perform the same. If you don't yank on the cables then you won't have any problems. It's difficult to say just what justifies AudioQuest's pricing structure. Audio cable jewelry? So it's your money and your preferences that come into play. Buy what soothes your soul.
