Is the sound of ATL plug performing the best?


I read an article as:

 ATL ETP-M16RH ETP-F16RH 
16 Amp Pure Copper Plating Rhodium Power connector
100% conductive
4 layer non - magnetic plating
Comprehensive upgrade
D I Y the highest level


Are they good?

Usually, the best thing to do is to upgrade your speakers, or add better room treatments.
