Separate Ethernet runs or one, then to a switch?

My wifi router is about a 25 ft cable run from my AV system. I can run 2 or 3 Ethernet cables from the router to the equipment, but should I run one cable and connect it to a switch such as Etheregen (my max budget probably) or any other kind of switch/splitter  to go to the equipment? I may have an integrated amp or preamp for Qobus streaming there eventually. Now I have a Bluesound Node2 into an Anthem AVR and a separate Roku.

Or maybe 2 runs. One dedicated for the (BS Node2) streamer (or eventually an all-in-one integrated) and a second one for everything else with a switch/splitter for them.


or


Place the switch at the wifi router with a short patch cable, and still run the multiple lines from that location to the equipment?

Is there a best practices for this? 

Thanks
