@arafiq,
unfortunately I am not familiar with your router. Assuming it‘s 5 or 12V DC though, you have a wide choice of LPSs. I have best experience with Kingrex but have also used $100 LPS on Alibaba with good results. The effect is best described as lower noise floor, less harshness in the treble and overall more air around individual instruments in a wider sound stage.
As to the switch: my experience has been that I got better results from the EMO filter than a standard switch. I cannot comment on ENO or Etherregen from personal experience. The Etherregen with its optical and 10m inputs sure looks intriguing, though
