Solid core OFC vs stranded OCC copper

I use and prefer OCC copper in my interconnects.  I have less experience and therefore opinion about speaker cables.

Neither a Litz like the Cardas has individual isolated stands that give a more cohesive balance and -0 interactions Teflon dielectric ,I tested all 3  types before

rebuilding my Loudspeakers with the Cardas .

@mceljo thanks

I take back my statement about no experience with OCC speaker cables as I have Zavfino speaker cables, not the top of their line, in my exercise room system.  I love them.

There is no audible difference between the two types of wiring. The only time there is a difference is when one is more expensive than the other because the electrons know what the cost of the wire is.
