Building Speaker Cables

I have made many cables with both the FP-201 spades that use set screws, and the FP-203 spades that can be crimped, as well as with spades that need to be soldered such as Cardas GRS and CGMS spades.  With the FP-203 spades I have used hand crimpers and, for the past 10 years, hydraulic crimpers to forge a virtually air-tight bond between the spade and wire.  I have not heard any sonic difference that I would attribute to the type of spade or connection.  My only observation is that the Furutech FP-201 and Cardas CGMS spades seem to fit on my binding posts a bit more securely and so I like those two better than most others.

IMO, the OP will be just fine with his plan to use the Furutech FP-201 spades and associated set screws to secure his wires.

Silver solder yes. Shrink tubing, yes.

I see no posts/discussion from Williwonka on DIY Helix cabling

There are Two Threads on this and a Link to a Web Site that originated the following of the build design.

This is a Scratch Built Cable, one chooses their bare wire and gauge, insulator, termination, there are many descriptions of what was detected as an End Sound, when a particular permutation for materials are used in a unique system.

As in all cables, systems are not ubiquitous, hence not all discoveries made and reported on will produce identical results.
