That'll surely help (and probably is part of what Devialet calls 'the new power supply') but of course it's the sum of all changes including but not limited to the addition of four extra filter inductors and increased thickness (double) of the PCB traces on the class D board.

Power comes from a supply but it must also be controlled. Plus the devices using the power need to be able to use it without limits other than those the designer intended.

Edit; I'm not sure if what I said here makes a lot of sense. What I meant to say is that I wouldn't "belittle" the changes other than the ones you mention. There's many more differences including the ones I already mentioned but also, for example, the bigger inductors on the board that got loose in mine. There's also changes underneath the black transformer cover which are detailed here in this video: http://www.digitalaudioreview.net/2016/0...-end-2016/

Don't take this the wrong way and I'm not saying that's what you think or said but in short I don't think your mods would make a non Pro model equal to a Pro model. Perhaps not even close.
