Yes the Wireworld Starlight is really good. Their lesser priced Chroma is actually very good value. It easily beat a long run of Audioquest Cinnamon.
I use a 8m run of Chroma between my wall jack and a Thunderbolt Ethernet adapter connected to my Mac Mini - and then a 1m run of Starlight between the built in Ethernet adapter on the Mac Mini and a Sonore microRendu. (A bridged connection sounds better).
Agreed. Wireworld Starlight hands down. Chroma like you suggested isn't bad but Wireworld wins in the long run.
