I have built all my interconnects and speaker cables. I use Bluejeans cable and furutech connectors. Great results. The sound just as good as some high $$$ cables that I had. And yes I sold the high $$$ cables.
Building Speaker Cables
I have decided to build my own cables. For the cable I’ve chosen DH Labs T-14 cable for the cable connectors on the speaker side will be Furutech FP-201 (G) spade connectors, amp side will be Furutech FP-200b (G) banana plug connectors. Would it be overkill to silver solder all the terminals before sealing the connections with marine grade shrink tubing?
