Pimp out thy router – Not with carbon but light fibre shall ye do it. So says the law of LHY, subsidiary brand of Jay's Audio. They  just released the FMC [$494], an RJ45 ⇒ SFP converter with linear power supply and 10MHz OXCO clock. If you have a LAN distributor from the same catalogue as their SW-6 or SW-10, you can now hardwire your router to their fibre-optic ports via the FMC. Hello ultimate network noise isolation. The same goes for network streamers like Lumin's which offer dedicated SFP inputs. Good-bye network switch. Run straight from the FMC to your streamer without CAT5-type cable or WiFi. Commercial fibre-optic cable is dirt cheap, ultra thin and for any conceivable domestic install length insensitive.
