If you're after decent shielding to keep RF out of the circuit, Radio Shack might have what you want. Nowadays a "high impedance" is typically 1 or 2K ohms instead of the 50K ohms are more common a few decades ago. Audio cable shielding has been reduced accordingly - especially from lower-cost suppliers. Where audio cable shields used to look much like the shield on good RF coaxial cable, nowadays it's common to find RS and other low-cost cables have a "shield" that consists of a few strands of bare wire running parallel to the insulated center conductor - maybe 10% or less shielding.
For that reason I make my own using RF type coaxial cable. RG-174 makes excellent lightweight shielded cables with a diameter of about 1/8".

I need one end to be a phono plug and I assume that the end that connects to the K3 is also a phono plug. Does anyone have any suggestions looking through the Radio Shack website as to the cable that would work the best. Thanks for your help!
