Where should I put new Furutech GTX-D Rhodium outlet?

My system has two 15 amp circuits (same leg), one is dedicated outlet for my Classe CT-2300 Power Amplifier that powers my Focal-JMlab L&R Utopia Be speakers via Morrow Audio SP 6 cables. Current outlet is Gaofei Red Copper.

The other 15 amp circuit powers the rest of my system, but the target outlet there is duplex shared by my Classe CT-SSP and my Fosgate Signature Phono Stage. Interconnects between all three of these components are top level silver Anti-Cables. All two channel listening is done in analog bypass. Current outlet Gaofei Rhodium Plated Red Copper.

So I am looking for advice (opinions) on which of the two outlets replaced with the Furutech would provide the most improvement to my system.

Thanks in advance for any response!
