Ok: My Update after a lot of kind help here, dowsing, pontificating, Dunning-Kruger deprogramming, reading, writing and arithmetic (or something like that).
1.) Alex (co-birth father of the EtherRegen) is beyond nice and helpful. I had emailed him about power supplies for the EtherRegen. He asked me what I was using and I told him an AfterDark: Linear Power Supply x 2. FULL STOP. I had written to him as the AfterDark: Linear Power Supply was hot to the touch and I thought something wasn’t quite right (it powered both the AfterDark clock and EtherRegen). He told me not to use the AfterDark: Linear Power Supply x 2 to power the EtherRegen as it canceled out functionality. How right he was! Using both power taps was the problem. Into the EtherRegen went an iFi iPower Elite - Low Noise Power Supply Adapter (12V). My wife came into the listing area and (unasked) told me the sound was better and what had I done? (This from the woman who’s eyes roll back into her noggin when I even get close to the outer phalanxes of all things stereo.) Better as in Wowzeer. Additionally the AfterDark power supply is cool to the touch.
2.) The other thing Alex told me was to run fiber/SPF (and to use Single mode fiber optic cable.) from a switch with SPF into the EtherRegen as that’s the best way for the cleanest signal. I got an Enterprise one from Ubiquiti. Bam.
