Do any of you have experiance making stereo RCAs both ways and have the unbalanced cables shown any more noise that the balanced ones.

balanced info:

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.

Hans

Its 16-18 gauge wiring, forgot the exact size.
It was in a 60 feet spool I had, Not sure about the brand but its sort of generic wiring. Though it sounds great! All I can say when I hook them up is BIG soundstage and more depth in the music.

If I wanted to wrap the a whole cable in heatshrink, where would I buy it from and how would I do it? Also I would prefer to buy it from somewhere that sells some nice techflex as well so I can combine shipping. Thanks!

BTW about how much would it cost to buy about 18ft of techflex and heatshrink?
