Solid core OFC vs stranded OCC copper

I used Cardas for my speakers and amp , but it is harder to work with than other choices .  24awg from RCA inputs to 9.5awg to speaker binding post outputs .

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?
