I researched a fair amount before I upgraded my ethernet cables.
Found a few who suggested unshielded Cat6 as the final cable to your streamer.
I have 10m of Blue Jeans Horizontal in-wall Cat6a from my router to my wall outlet (to be installed this month). Settled on Triode Wire Labs ’Freedom’ ethernet cables from wall outlet to switch, and then switch to streamer. The TWL Freedom is unshielded Cat 6, copper cable with Telegärtner RJ45 plugs.
