@audioman58 -- I have the opticalRendu in my second (home office system). SmallGreenComputers sell a bundle that includes a separate power supply and an FMC bundle -- the cost of the bundle adds an extra $200 I think. My system is setup like this ...
Router >> Switch (which is optional) >> ethernet cable >> media converter >> fiber optics cable >> opticalRendu >> USB >> DAC
The only additional step compared to other streamers is that you insert a fiber-to-ethernet converter in between the streamer and your ethernet connection. It sounds more complicated than it really is. The other option is to buy a network switch that supports fiber optics output.
