I always love a mystery, and when a mysterious box appears from Frederik Carøe (Duelund Coherent Audio) I get intrigued real quick!

I go through the same procedure as I did as a kid during Christmas time when checking out presents under the Christmas tree. I picked up my presents, considered their weight and size, and gave them a little shake to see what I might hear. 

So I picked up Frederik's box, and its big, but light in weight. I gave it a little shake, but didn't hear much. Hmm.

Out comes the box knife to cut the tape, then I pulled out the packing, and voilà, a spool wrapped with the new 600V version of the Duelund Coherent Audio DCA16GA tinned-copper wire appears!

The new 600V version of the DCA16GA Sn-Cu wire!

The 600V DCA16GA tinned-copper wire joins the 600V DCA12GA and 600V DCA20GA in the Duelund Coherent tinned-copper cable product line.

If you are new to the Duelund line of tinned-copper cables, you might want to read my Positive Feedback article "An Adventure in the Art of Tone with the Duelund Coherent Audio DCA Series of Tinned-Copper Cables, Part 1" (HERE), that gives the background about their origin, and of course describes their musical and visuospatial performance in the applications I have tried them in.

The original lineup of Duelund tinned-copper cables were intended for signal level applications, like headshell leads, interconnects, or speaker cables, for example.

The original version of the DCA16GA tinned-copper wire (above) is clothed in a baked oil-impregnated cotton dielectric. 

The new 600V version of the Duelund DCA1tGA tinned-copper wire is clothed in the new Duelund PolyCAST dielectric that was developed to allow for the 600V rating.

Per the Parts Connexion description, PolyCAST is “… a unique thermoplastic resin composite, which emulates Duelund’s “Signature” CAST process”, which means it is similar to the deluxe CAST damping material that is used in the Duelund CAST capacitors, inductors, and resistors - the black material you see in the 10uF Duelund CAST tinned-copper capacitor you see in the photo above.

The original Duelund DCA16GA tinned-copper cable uses 26 strands of 0.25mm diameter tinned-copper wires clothed in an oil-soaked and baked cotton dielectric, and the new 600V DCA16GA tinned-copper cable uses the same 26 strands of 0.25mm diameter tinned-copper wires, but with the PolyCAST dielectric to achieve the 600V rating.

Well, you know what the arrival of the new 600V DCA16GA means - I must experiment!

While I know this new 600V DCA16GA is rated for 600V so it can be used as hook-up wire in components or in power cords, where lots of voltage is flowing, I also value its differing aural properties for voicing purposes in non high-voltage applications.

I suspect the new 600V DCA16GA cable will be slightly mellower sounding than the original DCA16GA oil-soaked and baked cotton dielectric version, which is how the 600V versions of DCA12GA & DCA20GA sounded to me compared to the original oil-soaked and baked cotton dielectric versions.

Stay tuned for more on the new 600V DCA16GA tinned-copper cable as I get a chance to experiment with it!

As always, thanks for stopping by, and may the tone be with you!
