A couple of pics here. Under my desk in my office I use an APS continuous power supply and surge protector ($100 or so) to supply and protect my modem (top left), QNAP (not used for audio) and computer equipment. There are two cables going downstairs, an AQ ethernet cable and the green fibre cable. The fibre is coming out of a TPLink powered by a low noise iFi power supply. The ethernet feed into the TPLink is direct from the modem, not via the GS108 switch, which is not on the signal path. Downstairs the fibre is converted via TPLink again powered by a SOTM battery unit going into the Innuos server, which feeds directly to my audio system (not shown). The Venom and NR cables feed the Innuos and audio system. The Asus router is not on my standard signal path (wired via the Innuos), but when my wife and kids use the system via Spotify or Airplay, it goes wirelessly via the router.
The lack of a regenerator, and I did have one, is simply because I have very good mains and the audio system has a seriously good SMPS. The setup is based on low noise rather than clean power.
