Looking for Solid Core Speaker cables

Trying some Duelund DCA cable might change your mind on the merits of solid core. There is good reason many use it as internal speaker wire. Run the stuff bare and it will complete with far costlier alternatives. I am convinced there is something to the waxed cotton insulation that makes this cable outperform most others, solid core or otherwise. 

Tara Labs Time & Space (with return) were a great option years ago and they still sound good in my auxiliary system. I think Stereophile liked them a lot at the time. Solid core so they're a bit stiff but a very good choice if you can find a used pair.

Albedo Silver cables are absolutely fantastic from their entry level Blue Cable on up.  https://albedo-silver.com

Anti Cables, I swear by them, amazing clarity and bass... Currently running the new Flex 4.2 , one of the best bargains in HiFi, blew away much more expensive cables I had before like Audience ... 

I use Acoustic Zen for everything else, they make my favorite interconnects and power cords, I tried the Anti-Cables power cord and it was terrible compared to to my Acoustic Zen Krakatoas 

I never tried the interconnects but I doubt they can compare to Acoustic Zen Absolute that I use, but I would try them someday

I run Morrow Audio SP-7 speaker cables and am very happy with their performance.  I’d suggest their SP-6 line as the best bang for your buck.
