Hello, did you use the Grun version of the Atlas Mavros ethernet cable?
If so, did you listen with and without grounding the cable?
I have the basic Wireworld Starlight connected from the modem to the router. It's sound quality was noticeably better than the cheap cable I previously used. However, I wasn't able to hear the differences between ethernet cables until the modem and router were fed by a linear power supply.
Search other threads in Audiogon regarding powering your modem and router with LPSs.
High quality ethernet cables can expose a weak point of your system which might be dirty AC.
The combination of LPSs and a better ethernet cable made a positive improvement in my system.
