Special Note: I recommend the twisted pair be wrapped with a couple of layers of Teflon plumbers tape for better performance of the DC umbilical. The assembly should then be covered with Techflex braided sleeving.

A simple twisted pair is ideal for a DIY DC umbilical project. Specifically, Mil-Spec silver plated copper, PTFE Teflon insulated wire is an excellent type of wire to implement for for an audiophile quality DC umbilical. While I find the sonic signature of Mil-Spec wire to be unsatisfactory for AC applications, it sounds great for DC applications. The performance level of a mil-spec DC umbilical upgrade can be equivalent to an interconnect cable upgrade due to better clarity vs. an ordinary stock PVC DC umbilical. It can also be considered equivalent to an audiophile power cord upgrade vs. a stock PVC power cord.

Shielded twisted pair mil-spec DC umbilicals are also excellent, but can be a bit more difficult to terminate vs. a simple twisted pair.

Much better DC power plugs do exist .. .like xt60 - beppe61 00:08:31 04/24/15 (9)

Those look very nice indeed, but there's one problem - 1973shovel 09:17:44 04/25/15 (8)

The XT60 appears to be an inline connector. - Duster 09:07:28 04/27/15 (5)

It depends on the device you're powering - 1973shovel 18:08:32 04/27/15 (4)
