Is anyone else suspect that Netgear Powerline as an Ethernet solution introduces ac power mains noise into the system?

Reason I’m asking is that google Chromecast Audio runs off WiFi, but they sell a dongle that can create a powered ethernet connection, but the only way I’d use that is with a Netgear Powerline, so I wonder is this a futile chase for better sound with the possible intro of ac noise (I can tell that it’s a much more reliable internet connection and cuts out much less.)

Opinions welcome!

I can't answer your question but if you wanted to clean up the Powerline connection you could add a pair of fiber media converters between the Powerline ethernet jack and the Chromecast. Details in the link below. It's been discussed on AC.

You may already being doing this but you could also take digital out from the Chromecast and feed it to a better DAC with/without reclocking, jitter reduction, etc.

Yes I’m using toslink to a schiit Modi Multibit.  It still sounds flat.  Will try the isolation thanks!
