Happy 4th to all in these United States. The following is just a rumination...
I’m getting the itch to change(notice I did not say upgrade) speaker cables. I currently use 12 gauge Anticables. Of course now they offer a doubled up version at 9 gauge. My speakers do not have bi-wire capability, so that is a non-issue. The 3.1 version of their cable is simply their 2.1 cables with an extra pair of wires.

This is also a factor in my head, FWIW. Supra does sell a smaller gauge wire of the same type(stranded copper with tin plating).
Lastly, I will say that I run rather long lengths of wire-18 ft., and 23 ft. Therefore, these two contenders are likely all I can afford to try. Others out there run into megabucks.
Any thoughts or experience on stranded vs. solid core, etc., are appreciated.
If it makes a difference- speakers are Spatial M3 Turbo S, amp is Luxman L-590 AX Mk2.
