I am in the process of making a batch of RCA/RCA line level audio interconnects. These will be used to connect hi-fi components.
I have looked over the web and need some advice. What is the best cable to used for audio interconnects? I have so far found 3 options, and will list what I have found for them.
- 2 or 4 conductor mic cable
This allows one conductor for signal, one for ground and the shield can be disconnected at one end of cable, to allow low noise and hum.
- Coaxial
This has very high shielding against noise and very low capacitance, but there is a debate on Characteristic impedance matching, being 75ohms and not 50ohms. By the way, I have found discussion that RCA connectors are not 50ohms.
- Standard screened single conductor cable
This seems to be the standard configuration. Single cable to signal and shield to ground on plug.
I have a longish run of 30ft, so I am keen to avoid noise. I am also loathed to spend big bucks on shorter interconnects, when I have a soldering iron.
Any advice on the best type of cable would be helpful and appreciated.
