Looking for Solid Core Speaker cables

Cardas cables are also solid core copper and made from multiple strands of small diameter wire configured according to the golden ratio.  Many like Golden Cross or Golden Reference, which are occasionally available used at reasonable prices.

I use Kimber 8PR as they put their "varistrand" grouping of solid core wires in this cable and the 8 version puts a 10 guage total into each leg. A great sounding cable for peanuts.

Side question, I’m not that smart. Do you guys put Anti-Cables in this category or did this whole topic fly right over my midget mind ? Disparaging comments are ok, thanks. Mike B. 

Thanks for all the input. There are so many exotic and cool designs I did not know of. So appreciate all the input.

First, and I did not mention before, I need 3 runs of 21' and 3 runs of 13' of cable. Yes, I tri-amp each speaker which has 3 drivers...so a LOT of cable, which for economical reasons prevent any high-priced stuff in my situation. I am not going to spend 10k on cables ;-) 

Second, when I said "solid core" I had a very narrow definition in my mind. Max. 2 strands in a twisted pair (or star-quad) configuration or very similar minimalistic approaches. The mentioned Kimber 8PR definitely does not meet that standard (even though interesting concept). 

I was more looking for something like this https://jantzen-audio.com/wp-content/uploads/006-0085.pdf

(I ordered some to make some tests...)

And yes, I like the idea of DIY, and while the Neotech stuff looks great, some silver plated copper could work also work well....

I would message Chris Van Haus at VH Audio and see what he can build for you.  He carries many brands of cables and bulk wire with high end terminations.  He will custom build.  I have bought a few custom cables from him; he has always been honest with me as to what it will sound like.
