Where to Place Network Switch

Good Day Audio Fans,
I will soon receive a network switch.  I am getting an Ansuz Power Switch for ethernet distribution and noise reduction.  I currently mainline my ethernet from the router to my dCS Lina DAC & Master Clock.  Do you think it will make a difference if I put the Ansuz on the Router side of the ethernet cable versus the DAC side of the ethernet cable?  I’m thinking if there is no difference, then I could put the switch by the router, and plug in my home theater equipment (TV, AV Receiver & Blu-Ray player) as well.  The home theater room is just a wall away from the router but the main audio system is another floor away with a 50ft ethernet cable.
