Hmm, thanks for letting me know. I'd be interested to know if the LPS makes a difference. There is a UK company offering a wall wart with integrated battery, for power outages. I wonder if that would be another tack. B
Yes an LPS makes a big difference with a router, cleans up the noise along with grounding the router to a grounding box like Entreq using a Ethenet port to grounding box especially if your using a ethernet dac or streaming.
