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?
