I like the idea of using quad star cable to make a set of stereo RCAs using a pair of blue and white wire for signal and ground per channel.
But i read that to make a balanced connection the cable should use twisted signal wires and use the shield as the ground for both channels.
Do any of you have experiance making stereo RCAs both ways and have the unbalanced cables shown any more noise that the balanced ones.

Hi, As you may know I manufacture cables myself. Here are my experiences and methods I use. (and ofcours all is my opinion but sofar my cables have never been rated to have a bad performance)
All my cables use twisted signal wires, whether unbalanced or not. It seems (and I experience this with my own ears) that twisted cables have a good influence on the frequency characteristics of the cable which is established by the positive influence from twisting to the capacitive value.
The single return lead is always in the middle around which the signal wires are twisted.
For longer cables in environments where a lot of radiation/disturbance etc can take place I use a braided shielding to cover the cable and this shielding is connected to the earth at 1 (one) side only and preferable the ground at the component where the signal originates from (e.g. pre-amp, iPod).
It is also my experience that for short(-er) distances unbalanced versus balanced shows very little to no difference. This is also logical sine balanced was created for professional application and thus longer distances on stage and in studio's for example.
I hope this is of some help to you.
