Expert Pro sound quality

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.

It does make sense Antoine and sure I know it's the sum of all the improvements that makes the PRO-Sound.

I won't say that my mods make my D200 equal to a D220. It's because if you alter different parts/components of an amp you can not compare the achieved sound improvements. They would differ in several aspects. But you would get a tendency (e.g. eliminate the IEC-Filter-Component) of improvement. That's what I was talking about when I (did I?) compared it to the PRO.

Actually there is another mod I made first of all the others that gave the biggest impact but I don't want to talk of it yet (no Devialet-Style intended).

As I also had some D250 on my workbench to modify and the modded D200 (with first mod) was compared to an original D250 the D250 was outperformed by far. No chance ever.
Though if one knows the improvements in sound a D250 has in comparison to a D200 in original you could imagine these improvements (e.g. subtle resolution) 'under the hood' of the D250 but they would not come to surface (kind of nebulised) and the D200 (mod) came out with more clearness/stability/control.

If all mods were made to both the original difference in sound of the two is restored hence the D250 outperformes the D200 again.

p.s. I really like to do a comparison of new/old(mod) but it seem's not to have as many PRO models in Berlin yet. Or are there any who like to do a comparison?
