@veroguy I love my Gigafoil (w/LPS) and just ordered another for my second system. Also had an EtherRegen upstream just ahead of the router. I recently added the ENO Ag after the Gigfoil and right before my Streamer. I felt I didn't need the EtherRegen anymore. However I don't have my router powered with an LPS. Did you try A/B'ing with and without the LPS on your router? I don't want to invest in another power supply if it isn't necessary.
