Yes and even without  Phantom integration, if this PLC function can connect to my Devolo PLC encrypted network, it would allow me to get rid of the plug I’m using currently to connect my D220. 

As per the impact on SQ, I have never perceived any negative impact, and I’m of the opinion that with products thay have properly designed PSUs, which is explicitly the case of the pro version which is mentioning PLC compatibility, SQ is not a problem.

PS: as per my signature you can see that my D220 pro and my D110 before are/we’re fed by PLC.

My experience with PLCs goes back to my time with Naim. For anyone who's interested there are countless posts on the Naim Forum from users who had issues and responses from Naim tech support who commented that they had received numerous calls from customers with various issues that were resolved by replacing PLCs with hard wired Ethernet.  

There are many objections to PLCs. From a hi-fi PoV probably the most important is that they inject noise into the mains (not just from their PSUs but also the transmission signal itself) which can then negatively impact SQ.  

Perhaps the mains filtering in Expert Pros is more effective than that in Naim pre-amps which is why you are able to use PLCs successfully?

I can understand that a fully analog design with a linear PSU gets affected by PLC if you have anywhere some non linear distortion that results in frequency components that fall back in the audible frequency band.

The design of the Devialet with its switched PSU and its ADH design is very different. In particular there are intrinsically high frequency signals (inherent to the class D amplifiers) that need to be efficiently rejected by the A part of the ADH, and therefore I am convinced that class D amplifiers and ADH amplifiers are much more immune to the effect of PLC than pure analog amplifiers.

Hi Jean-Marie,
would also not problems with analog applications. On the market there are special high-quality PLC filter modules, for audio applications !!
