Duelund shielding

I use the DCA12 Gauge as-is in both of my systems with no addl. shielding.  Great cable and a tremendous value... no need to spend more or add shielding IMO.

I didn't try it with Duelund cables but I DIY speaker cables with similar construction and providing a shield improvement the sound quality (mostly blackness and image). The shield having equivalent gauge is used as the ground lead. The added capacitance will provide a path to ground for high frequency noise. Give it a try to see if you like it.

A shield can keep RF out, but whether it affects the sound is unknown.
But the extra capacitance would form a filter to diminish the higher notes.

One sort of needs some proof as to which is happening to assign a root cause to the effect.
And it is unclear whether the effect is real.

In any case I am assuming that the shield is floated at the amp and speaker, and tied directly to some ground like the safety ground?

And the other good news in that the cotton would make the addition of a shield have a lower capacitance than it wold have with a higher dielectric constant material. So the cotton coming in lower.

Thanks all, for your comments

@mitch2 , I'm not intending to use connectors, but will follow the advice in this review. 

My speakers (ATC SCM40) are 3-way and have 3 sets of binding posts.  At the moment I have the supplied metal jumper bars in place.  I had up to this point been dreading having to buy 2 sets of jumpers for my existing cable (TelluriumQ Ultra Black II).  But, instead, I can use bare wire.  Just have to be careful there are no stray strands which might short the amp.

I have made ICs from the Duelund 20awg (DCA20GA600V) Tin Plate Copper Hookup Wire and shielded those cables using tinned copper braid shield connected at the source end only.  The cables are balanced/XLR interconnects and they sound good with no noise issues.

@mitch2 I am wondering… why not tie the shield at both ends of the XLR?
I need to make set of XLRs, and have wire of a similar construction in 20 or maybe 23 ga.

Because the shield is being used as a shield only - I run a separate, third wire for ground that is connected at both ends.
