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).
