Audioquest DC cables - why are there almost no high end DC cables?


Hi everyone,

I noticed it's very difficult to get high end dc cables.

Why is that?

Surely a lot of components use DC connections: LPS, DAC/Streamers, HDD's, Switches.

I have been reading that a good DC cable need 2 things:

1. Geometry: starquad
2. Thick awg (12?)

Now I want have a DC cable made with audioquest wiring. These tick the above two requirements.

Can I use AQ type 4, CV4 or Rocket33 to make a DC cable?

The plug I will be using is Oyaide. Oyaide has high quality DC plugs in 2.1 and 2.5.

Ideas?

yeah, the total cable is 16awg, but it uses 2 x 19awg conductors for each leg.  I was going to mention that the Audioquest power cord is quite stiff.  If you want to completely strip the outer cover and then just use the individually insulated conductors, you're better off just getting straight chassis wire.  Look at the Neotech 20awg Teflon OCC:

Or, if you want even better wire, try the Unicrystal OCC hookup wire from VH Audio:

Then just use as many conductors for + / ground that you need.  Every time you double a wire, you increase the awg by 3.  For example, 2 x 20awg = 17awg.  3 x 20awg would be something like 15.5awg.  You can twist the wires or braid, then cover with heatshrink and/or techflex.  This would be more flexible than the Audioquest NRG cable.

If you do VH Audio, 18awg is what I would suggest.  Or use 18awg + 21awg to make the cable.  VH Audio has different colors you can order so that you can identify + / ground.  The Neotech wire is all red.
richardhk - take a look a Ghent cables - they are making up star-quad DC cables for reasonable prices

star-quad alters the inductance to act as an inductor (choke, ferrite beads) and reduce RF noise injection to the DAC

An LPS is not a bad idea either
You folks may be over-invested in the star-quad construct.  I made several PCs that way from TFT-insulated silver-plated copper wire that were subsequently trounced by thicker, pure silver wire in a simple twisted pair with a foil shield.  It's worth a try.  Thick silver wire is too expensive for commercial marketing, but relatively cheap for DIY.       
"yeah, the total cable is 16awg, but it uses 2 x 19awg conductors for each leg."

the site says 2 x 16awg

so does that mean 2 poles and in total 16 awg?

I read it as 2 times 16awg, so 1 x 16awg conductors for each leg?

This is what I found on another site:

thickness conducturs: 2 x 1,31mm²

The main question is: will it fit an Oyaide 2.5 and 2.1 DC plug?

http://shoponstage.com/Oyaide-DC25G-DC-Power-Plug

Body Material: Gold-plated brass finish
Cover material: Berri brass chrome-plated finish
Plug Type: PL03A (φ5.5mmxφ2.5mm)
Max Cable O.D.: 6.3mm
Accessories: Comes with three silicon spacer rings
Manufacturer Oyaide electricity

Maybe by taking the sleeves off at plugs end?

We can use heatshrink to cover the sleeveless plugs ends off?
