Solid core OFC vs stranded OCC copper

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.

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.
