I also have Zenith MK3 with Ph’USB and Ph’Net. Reasonable to assume the PhoenixNet would make the Stack unit superfluous? Also, galvanically isolated between my DAVE and M Scaler.
@cantorgale I bet that sounds really nice, I have thought of trying the Phoenix USB. My guess is that those two offer the isolation that you need. One question, how long is the ethernet between the Phoenix Net and your streamer? A very long run could negate the gains of the fancy switch.
