The use of PLC and mains filtering was discussed at the 1000 Pro launch event back in July 2016. Devialet's Mathieu Pernod explained that the PEM used in the D-Premier, Expert and Od'A will filter out PLC signals. The Pro with the new OS board is designed to work with PLC together with Phantoms. So mains goes in to the Devialet un-filtered, PLC can then go to the new streamer board, the mains is then filtered further inside the Devialet to power the amp/DAC itself. Apparently the mains filtration in the Pro is superior to that used in the Expert, which itself is clearly good enough to filter out PLC.
Personally, I would not want to use PLC for audio for noise / sound quality reasons. That said, I am not worried that it is being included as a feature. If you happen to need it, then it's available, if you do not want to use it, then disable it in the configurator.
