Wire world Eclipse are better then most in a lot f ways ,any type of stranded in a minus to start with
For all strands micro arc that is a dac which = more distortions Wireworld use individual wires different gauges
In the lowest dielectric out there and the Purest OCC Copper = 7-9s pure none better .
And very important connections ,pure Copper silver plated , and spades or bananas can be changed by their screw on connectors and they have the Eclipse Copper then 3 grades higher up to the Platinum line ,
Vs the competition very accurate and clear ,excellent value perr $$ ratio. I have tried many ,I am speaking through experience ,check them out before making and decisions.
