Solid core OFC vs stranded OCC copper

I personally prefer to sonic signature of solid core OCC copper.

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

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.

I will say it again.  Some people cannot hear differences between stuff like wiring, caps, etc.  And because they can't hear differences they believe that noone else can.   True, they get to save money.
