Yeah that's what I meant crut. Some audiophiles will swear you need shielded cable for long runs, but there's no sensibility behind it, the chances of picking up interference that could actually produce noise on a loudspeaker of decent power is nill, unless you're running the speaker lines parallel to heavy duty industrial type electrical lines. If it's a signal line that you're running IE where you're just transmitting a signal not the actual power then shielding is very important because the amplifier at the powered end will amplify the small amounts of noise you'll pick up to audible levels. Watch out for ground loops when you run shielded cabling though, I'm not sure how it effects shielding effectivness but if I'm not mistaken only one end of the shield needs to be grounded to avoid interference so you don't need to ground the shield at both ends which can cause ground loops.
