Fiber Optic Internet...best way to connect to system

You can insert an optical connection (can be done for about $80) between the router and your Node that will shunt away the inherent noise, then you can get a better DAC if you’re currently using the Node’s internal DAC. 

BTW, I’ve been hearing Fios is really the only service that offers fiber right into the home.  Could be wrong, but Consumer Reports ranks Fios higher than most other service providers.  Google is a new player and seem to get really good reviews for price and performance but not available in my area so not sure.  Regardless, inserting an optical connection between ur router/switch at some point before going to ur DAC or whatever seems to be a good idea.  Best of luck.
