Does it matter the wire gauge used in interconnects?


I am thinking of trying my hand on building some DIY interconnects. It will be balanced (XLR) and 10 feet long. I have seen interconnects made with thin 30 gauge wire, is there an advantage using super thin gauge wire?
I was thinking of using 20 gauge but is that too thick for interconnects?

Thank you for the response.
I am thinking the longer the interconnect the thicker the gauge should be. That's why I am considering using 20 gauge for a 10 foot run.  I believe that should lower the resistance / capacitance. But, thinner wire may have other attributes and may be beneficial for higher frequencies.
So any advise on this subject is welcome.

Thank's for the help. I'll check out that information.
I guess I like the Xhadow XLR's because they use screw connections, thus eliminating solder.

twoleftears,
Thanks for that info. I have tried Duelund wire, and although its good , soft solid .9999 silver wire is better. At least IMHO.

grannyring,
Thank you for chiming in. I don't understand why doubling up the cable is better than just using a heavier gauge wire? And, I need 10 foot lengths.

ozzy
twoleftears,
Thanks for the link. It will come in handy.
Perhaps I missed it, but it's still not clear to me how various gauges affect the sound.

kijanki, audio2design,
You guys really know your stuff. Thank you for that very helpful information.
So for now, the plan is to use 20 gauge soft .9999 solid silver wire with oversized PTFE tubing and braiding the cable slightly.

I was thinking of using Xhadow XLR connectors but they don't seem to be available anymore. When I look at the XLR connectors that are available they seem to use a lot of metal in there design, which to me seems like it could affect the sound.
Is there any XLR connectors that use minimal metal like some of the RCA connectors I have seen?

ozzy
Mitch2,
Thank you for that information.

Nonoise, Yes I believe using oversized tubing is a plus.

grannyring,
I already ordered 60 feet of .9999 20 gauge soft silver wire along with oversized  PTFE tubing. To keep the cost down, can I also then add 60 feet of copper to make the double runs?

Then not sure if it will all fit into a XLR connector...

ozzy
Interesting, I may try my hand on the double helix method grannyring refers to.
But, then I also agree with auxinput comments about using too thick of wire aggregate. Thus my original question.

ozzy
Thanks grannyring for the additional information. Since I have already ordered the materials I will try a single run first. Perhaps later I will try the dual runs.

My experience with using heavier gauge interconnect wire is that the highs are not as pure.

ozzy

It is amazing how different lengths, gauge and conductor type can have such an impact on the sound. Not to mention, stranding, twisting, looping, and then the dialectic, shielding and all the other variables.

Oh, how I wish I had the Synergistic Research capabilities...I would probably try 2+ million volts!

ozzy

auxinput,

Interesting, are you saying to combo copper and silver together?

Ted, I hope you know that I was just kidding. I really like SR products and the innovation.

ozzy

auxinput,

The price for silver wire from VH seems really high. I can buy .999 16ga. solid silver wire for about $10 a foot.

digsmithd,

It’s about what sounds the best. Even though I have tried several (many, many) interconnects through the years using all types of different wires/configurations, the Shunyata Sigma V2 has been the best (thus far). And I'm not really sure what size or type of wire that is used.

ozzy

Auxinput,

When I used the silver wire it was with oversized high quality teflon tubing. I believe that air is supposed to be the best dialectic. I'm really not sure what OCC silver is.

ozzy

digsmithd,

I am really not sure as to the Shunyata gauge. They have a couple of innovations in the design.

And yes danager, everything seems to matter...
