Hey - @
Antoine - to give you credit - the top picture of the inlet above is your actual 250 Pro !
I note that fuse F1 is on the side we think is live, which would be logical.
Although it does not resolve this issue completely, I think a question to Devialet will be the only way to be sure.
No, I think that is part of the marking for the square component. Similar markings for other components (like F1 and F2 fuses)

The Pro models no longer have an integrated ‘off the shelve’ inlet filter like the Schurters as Devialet built their own (I suppose to not filter out the ethernet over powerline frequencies. Functionality they haven’t enabled yet BTW). One can see the differences on the picture in the review @Nakatomi63 also mentioned.
Earlier I had already searched for clearer pictures to check for markings but couldn’t find any so for me this is still an ‘unresolved matter’. 
Antoine, you're Dutch. Do you make sure you have your phase connected correctly?
Hi Pim, if you mean have I ever listened to both directions of the schuko to determine the best sounding one; nope I haven’t. I always assumed the right direction between Pro and non-Pro stayed the same. Perhaps others have, I’m not sure if I’ll try since the Shunyata powercable I’m using probably won’t allow me to twist it.

OK, cool!
I do remember taking a photo of the internals after I received mine ‘DOA’.
You could be right about F1 being on the live side but I agree, probably the only way to be sure would be to contact Devialet. But this is usually also the time the real confusion starts unless support contacts a proper engineer!
Like Ogs I also think the white ‘L’ is just the corner of the rectangles painted on the PCB.
Hello, the magazine Stereo tests the devices with both two pins as phase! The pin with the phase where the device sounds best is given as the reference point for the phase, always refers to the view of the built-in socket !! Since there is no EU/CE/VDE regulation in Europe where the phase is connected to a portable device, the pin does not matter! L and N are only indicated on the mounting sockets in order to have a reference point in circuit diagrams.
Whether left or right, it matters, the sound determines the pin with the phase !!

Small picture (yellow schema) has the pins vice-versa versus to big picture (real connector).
Pins are matching ("Mains phase" = "L") only if small picture is connector from the cable, and not from the device.

There is no Schurter AC filter in the Pro models, see my earlier post.
If Stereo did determine the ‘correct‘ phase through listening it’s a subjective finding. Nothing wrong with that but it’s not a fact. Others may come to the opposite conclusion.
If you need to debate whether the mains phase is right/left or wrong, you probably don’t have the ears to hear. Shame!

Hello all, try and then decide what you like better! Like everywhere else, eating, drinking, songs...

Well thank you for your positive constructive contribution to this thread..as far as I know nobody who posted in this thread has even tried left vs right (some even can’t without DIY’ing a power cable or changing the wiring in their AC outlet). Did you try, if so what were your findings?

Hi Antoine, when I bought the Expert (2016) I could not find any great effects when changing the phase. But today I checked where the phase is, looking at the device from behind "right" near the case, like the test of stereo !! Things look very different with my McIntosh, you actually notice when the phase is wrong. Especially in the high and middle! The difference between the two devices could actually be the construction of the power supplies, transformer and switching power supply! Could be, right ??
