There may be potential for a surprising aesthetic initially or down the road with the display stand if one's particular Devialet currently uses or might later use a high-end/high-current power cord that can't accommodate the rear cover due to diameter of IEC plug housing. I compensated for a similar situation with my wall-mount by mounting my 200 between my roll-top desk & wall with 70% of the 200 above and 30% below the desktop thereby hiding the missing cover & exposed cabling.
