Not a problem... they serve 2 different functions, the signal is only the signal but the ground also carries ground currents due to differences in potential between the grounds of the components it connects. The voltage of the noise caused by these currents is dependent on the ground wire's resistance due to Ohm's law, V=IR, and possibly also by the power cable's ground depending on the component's grounding scheme, but either way it's a benefit to use a heavy gauge ground conductor in order to reduce noise as much as possible. The gauge of the signal wire will make an audible difference and I'd suggest not using wire heavier than 24g and combining multiple runs into one larger gauge wire. 2-3 runs of 26-24g solid-core wire will work out well for signal and for ground I'd use at least double that, but the more the better. FWIW my D3/4 uses 6 runs of wire for ground making for a pretty robust ground connection.
What I don't understand is why Kimber (and others) use 2 wires for ground. Is it just to get a larger ground or does it serve another purpose?I can't help but wonder if an interconnect that only uses 1 hot wire and 1 ground wire and NO SHIELD would work.My system is so quite now it makes me think I don't need an interconnect with a shield at all.Damn, it looks like I've got another DIY project coming up. 5 pairs of 3 wire braid interconnects $$$.
I love the Belden's. I decided to keep them in my system and give the Parsec's to my son. They are crystal clear, black background, more so than the Parsec's. No brightness and no sibilants like bluejean cables. I would say that they are on par if not better than my Audioquest Columbia 72v DBS XLR's. I bought mine here-https://btpa.com/IC8402XLR-XX.htmlI do not notice any recessed midrange. They are a very balanced (no pun intended) sounding cable.
It takes big expensive machines and a good quality control department to make good interconnect cables.
A 3 wire balanced interconnect cable is a relic left over from decades ago. Then Neil Muncy wrote about Shield Current Induced Noise. That third wire or a foil and drain wire just add noise.Now good balanced interconnect cable is either Shielded Twisted Pair (STP) with a braided shield or Cat5 or 6 (more often unshielded).In either good cable, symmetry of both conductors from end-to-end is very important. It takes big expensive machines and a good quality control department to make good interconnect cables.
Speedskater,I read your post and link about DC offset on mains power. Thank you. I agree that a 3 wire braid may be a relic from the past, however, for unbalanced interconnects getting rid of the shield maybe positive.As I've stated previously I've built many interconnects using several Belden cables balanced and unbalanced over the years.What I have determined is that I don't need a shield for unbalanced interconnects. I'm about to shit-can all my Belden interconnects using 8412,1694A,9207,9463,89207, and 89259 for a 3-wire braid without a shield.I'm only going to do this one more time. Foreclosure on my home isn't an option.Here's the plan, unbalanced only, much like Kimber's Hero I think .(1) 20-18 gauge solid or strained silver wire for the hot, Undecided.(2) OFC copper wires for the ground.Note* What I have read is not to have the (2) ground wires larger then the signal Hot.I do not want a shield at all.Opinions please. Lay it on me.
SpeedskaterJust what does your system consist of?What perfect wires are you using?No one has asked.
Are you sure? I've read on multiple forums that some guys sell hand braided high end cables. How could they do such a thing otherwise?
I only write about good engineering practice, not this system or that.

A twisted pair is all one requires. A shield is not required for most audio level signals. specially since the standard has move up to pro 2v vs the old audio gear 0.5 volts.The one place an audiophile might need a shield is on phono cables, since that signal is pretty small voltage.
Engineers are well aware that there are differences in cables. My link above has some papers measuring some of those differences. There is paper after paper and book after book about making good cables.Now if I were to setup a new system (in any price range and either home hi-fi or pro audio), all the interconnects would come from Belden, Canare, Mogami or BJC.
