Analysis Plus Oval 9 Black vs Black Mesh

I have the Oval 9 Black, wondering the differences between Black and Black Mesh. Thanks. 
Have same questions...anyone know?
I called Analysis Plus. They said they were sonically identical. I forget the details of why the name change. 
I think it's the color of the jacket.  the older one is more purple.
The Analysis Plus “Black Mesh” oval 9 are considerably better sounding in all ways - but not sure technically how they achieve this.

They've been my reference cables up till I did a 2 month comparison with Tellurium Q’s newest Black II Cables ( ) and my Analysis Plus Black mesh Oval 9’s ( literally new) at similar price points!

quite intriguing exploration, INDEED!
