I suggest you build speaker cables yourself using Cat 8 Ethernet Cables
I’m 75, tried many speaker cables over the years, myself and my friends. They sound great, cost comparatively next to nothing, and there are advantages to having quality removable connectors. most are 26 awg (x8 = 17awg), I use 24 awg (x8 = 15 awg).
cat 8, 24 awg x 8 = 15 awg pure copper, S/FTP
S/FTP: SHIELDED WITH FOILED TWISTED PAIRS
Similar to F/FTP, the individual twisted pairs are wrapped in a foil tape before being wrapped in an overall flexible yet mechanically strong braid screen. The additional foil on the twisted pairs helps to reduce crosstalk from adjacent pairs and other cables. The braid provides better grounding.

I use two different colors, wrap them around each other, tape every 3 lf ; add expanding banana or spade connectors. easy each end to know +/-
add a bit of length to allow for wrapping them, leave slack both ends, extra length costs next to nothing compared to expensive cables. cut them after you make them, add connectors, done!
