Looking for Solid Core Speaker cables

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.

Wow!  That takes me back.  Still using Type 4 on one of my systems.  I have a 30-year+  history with Audioquest as a (semi-retired) dealer.  I remember a demo a l-o-n-g time ago of the $1/ft Type 2 against a large, multi-stranded cable we were selling at the time costing many times more per feet.  You guessed it.  The Type 2 sounded better.  We become "solid core" believers on the spot, and became an AQ dealer. 30+ years later we till use AQ internally in our performance mods. Rocket 44 is  our 'go to' cable for most speaker upgrades.

It sounds like you've had good experiences with the AQ cables you mentioned.  Today's market has many legitimate offerings, and I'm sure there are some strong "bang for the buck" options for you out there.  But, I'd certainly give the newer AQ offerings a look before pulling the trigger.

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.
