Solid core OFC vs stranded OCC copper

I really wouldn't obsess about this.

Thanks for the replies guys. 

@carlsbad lets say speaker cables. 

Stranded cables are actually made up of tiny solid core wires. Morrow audio stuff (which works fine) illustrate that point sort of, although they claim to be "small coated wires" bundled together...their top of the line "anniversary" speakers cables have 2,304 small wires...now that's some solid core!

I find stranded cables smear the time domain and never provide the attack of a single solid core wire. This applies to both interconnects amd speaker wire.

OCC silver has proved the most lifelike and detailed for interconnects. I tried different wires with same plugs as I make my own cables. My speaker cables are solid core soft silver (bendable and better sound) 4n pure.

Sound stage is holographic, detailed, phase coherent and wonderfully natural and tight.. Never had anything close with even two strands of wire doing the same job.

How good is your hearing?

OK.  So talking speaker cables.  I'm not aware of anyone using solid core cables for speaker cables.  Speaker cables should be at least 12 awg and preferably 10 awg.  That would be very stiff.  

Speaker cables can be made by weaving individual strands of solid core ofc copper into a round braid.  12 strands of 22 gauge is 11awg equivalent so weave 24 strands (half for positive and half for ground) would make a good cable.  I use a very similar speaker cable but each of the woven strands is also stranded.  I am very happy with their performance.

I do use ofc solid braided interconnects.
