Neotech UPOCC Silver Interconnects vs AZen

Has anyone had a chance to A-B Acoustic Zen Silver Ref 2 interconnects vs Neotech?

The latest offering from Neotech uses UPOCC Silver 7N. There are 2 versions NEI-1001 and NEI-1002. They also have a line one down which uses single crystal silver 5N. Has anyone tried any of these products
