Looking for Solid Core Speaker cables

Interesting, thanks.

I also consider similar designs to Type 4, e.g. twisted pair or star quad.

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 appreciate all the input. But please stick to my ask and talk about solid core design

I agree with small gauge wire! 

From the picture in the link it looks that one channel is twisted and hence the whole construction might just be star quad (which I like on paper). Question is really what "small awg" really means? Audioquest Type 4 seems on the larger side with 2x17awg and 2x20awg. 

As my speakers have 99db or more efficiency I definitely dont need thick wires. I am thinking 2x18awg and 2x20awg at the max or even 4x20awg. I know not typical orthodoxy but Acoustic Revive and Morrow (and DNM) seem on similar path..

Solid state, but again super high efficiency speakers, so while the amps have plenty of reserves, typically I would stay within one watt....

DNM has two cables, one is ~16awg and one is ~18awg. Only one conductor. So 2x20awg could work .... however, as I have longer runs (20') the combination of a 18awg and a 20awg might be perfect....I'll will try and see...

The longer I am in this thread the more I realize that we all have always insufficient data and backgrounds to have a one-size fits all approach. Way to many differences in amps and speakers (including crossovers, which my speakers dont have). Hence in the end, with limited (by definition) experiments, I will be stuck with a few experiments around a star-quad config.

Cheers all. Fascinating how diverse the market is...thanks for all the input

Tocaro 40F (single driver, 98db sensitivity, 40watts at 8 ohm) and

Tocaro 50F (3 drivers, hence tri-amping, no crossover, 103dB sensitivity and 3x 40watt at 8ohm)

They are the informal heirs of the (in)famous Rehdeko, which in my mind where a stroke of genius.

The Tocaros are super fast, toe tapping galore and very resolving....
