DIY Balanced Cables


I just finishing a pair of Balanced Cables for connecting an Ayre QB-9 to an AX7e. I tried to follow Jadem6's recommendations on his 2006 thread "DIY Interconnects Review".

The cables consist of 2 feet of cotton insulated solid copper wire (from HomeGrown Audio). The active leads (2 and 3) use 3 strands of 28 gauge. The ground is on one strand of 22 gauge. I used Neutrik Connectors. The wires are stitched by sewing machine on to a 1.5 inch wide cotton band the spacing is about 5/8" with the return in the middle. The three stands are lightly twisted but not braided. There is a small bit of electrical tape securing the cotton band to the connectors. I am not concerned about fragility. I will put pictures on my system page.

I would like to try some different configurations and wire when I have the chance but would like feedback about the following things.

1. Should the wires for the signal be left untwised, or braided rather than loosely twisted?

2. All the wires run parallel. I have found this to be a problem with speaker wires but jadem6's article is pretty emphatic that straight is better. In fact, I tried a version of my magnet wire speaker wires parallel and it sounded awful (veiled, thin). They are long wires though and carrying much more current.

3. What about a Litz configuration?

If these work well, I might try Gold wire but have heard negative things about silver and silver coated copper wire. Haven't heard them yet as my speakers are in the shop being upgraded. So as soon as I get them back, I will try them. i don't have much to compare too right now though.

thanks for any feedback (except really inappropriate negative stuff)

Drew, when you ran your magnet wires parallel, were there in close proximity/touching each other or spaced apart?
