Zavfino and Neotech OCC Interconnect

Hi @temmple,  While I use K-S Realization in my home system, I have found the Zafvino Arcadia interconnects an amazing value in my weekend home.  It is unfair to compare these two, just as it is unfair to compare the Zaffino's to many of these other expensive brands discussed.

For me, I want all copper cables in my resolving systems.  For the money, you can not go wrong with the Zafvino Arcadias.

Has anyone compared Acoustic Zen Matrix Ref II vs Cerious Technologies Graphene Matrix RCA Interconnects?  Both can be had here for about $500 used or refurbished.  The thought  would be to upgrade my Zafvino Arcadia RCA interconnects in my vacation home.  Thanks!
