@debrajray My thought along same line in a router, simplify the setup. Why do you need 2.5gb lan, you have super high speed internet provider? While I haven't checked lately, always on lookout for audiophile router.
My issue with SFP in router is I'm not aware of any audiophile SFP card for my custom server. Using JCAT Netcard XE in server so this mean fiber conversion post server which feeds the OpticalRendu streamer.
I've always considered adding a switch to be redundant/needless complexity for audio streaming, the audiophile switch I tried resulted in much poorer sound quality.
