Duelund DCA16GA

The oil is dried up and wax like. It coats the wire making for a less direct connection. That’s all.

@grannyring thanks for the info 

Mitch2 & Grannyring; I am settled right now with a combination of both of you recommendations.  I am using Bi wire 10 awg Western electric with no connectors(bare wire). Surprisingly in my system, the single wire sounded with less highs and little less defined low ended; everything changed with the biwire, better highs, clear low end, more dynamic and of of course the famous nice midrange that this cables are famous for.  Thanks a lot for your inputs. Cheers,

I just made two sets of 3.5M long balanced interconnects using the same construction method of a twisted pair of conductors encased in a noise-reduction braided tube as a spacer, then a tinned-copper braid shield connected at only the source end and then a counter-spiraled ground wire outside the shield and connected at both ends, with the whole thing covered in clean-cut TechFlex.  Both sets were made with Furutech FP-601/602(G) connectors.

The difference between the two sets of ICs was the wire used.  One of the sets was made from Duelund 20 awg tinned copper wire with a 18 awg ground wire and the other set was made from WE 16 awg tinned copper wire with a 14 awg ground wire.  

The difference between the two cables is interesting.  I like them both and would choose either in comparison to a pair of the same length of high quality Furutech u-P2.1 PCOCC 19 awg interconnects I own.  The Duelund 20 awg cables have nice tone and good dynamics.  The larger 16 awg WE wire cables have an even fuller tone and a bold, powerful sound.  The Duelund ICs do a bit more/better with the upper frequencies but I like what the larger WE wire does for bass and midrange.  The WE cables are not as burned in as the Duelunds, which spent 4 days on the Cable Cooker and then a day in my system.  I will burn both sets in more and report back.  I am very close to having my entire system wired with the WE (or Duelund) wire, including ICs, SCs, and PCs (but not my USB cables).
