Hey @wsrrsw @blisshifi ! We should visit each other! I've gone big in most areas, but limited my switch (ahem so far) to the Silent Angel Bonn 8. I power it off the 'other rail' of my HDPlex (the other rail powers my Nucleus+). I have seen and read on the Synergistic Switch. I probably would be all over it, but I don't have anything SR. I had not even heard of the M12 switch. I went all in on the custom Power supply by Sean Jacobs for my Auralic streamer, and was not disappointed!
I have two systems. In the 'better' one, (Aries G2.1 with custom power supply to stand alone Tambaqui, I found I did not need the EtherRegen so much in front of the Muon. Upstairs, where I have ethernet input to Makua Preamp with internal Tambaqui and ethernet bridge (no separate streamer) I find the inclusion of an EtherRegen in front of the Muon beneficial. I think it makes sense that the better streamer with better PSupply was fine without Ether Regen and OK with the Muon alone.
