D200 Mod 2.0.1

... I thought so too that a better IEC for the power cord would have been just a few Euros for Devialet to spend and would provide an overal better performance due to better power flow.

What exactly do you mean by "better power flow"?  How would changing the IEC connector have such an effect?

This is often gotten wrong. If you change e.g. the IEC to a "better" one there's obviously not more power transferred by the new IEC.
First...it's not exactly known how electricity is moving inside or outside (around) a wire...hence it might also be called magneto-electric and not electro-magnetic...imagine that for a minute (chicken-egg problem)?

Most people think of a 2-dimensional pattern or value on a display when thinking of electrical power, amperage, inductance, capacity or resistance. These are only measurements. Nothing in nature is only 2-dimensional. At least it is 3(4) dimensional.
If a sinus wave is displayed on screen it only shows a small 2-dimensional part of the actual power that is measured. It's not a picture of how power looks like. I know many of you're aware of that but we might forget such facts sometimes down the road.

What I want to say here is that it might not only be important that there is a good electrical contact between to electrical parts but also form of design and material might attribute to a good "flow".
Just a thought: Could it be that power has similar features like water (for example) when it is moving looking at it in a 3-dimensional way?
This is only an analogy...nobody knows the way power moves because nobody has ever seen it (only effects of it).

Look at how the connection of the IEC to the motherboard is designed on the PRO Devialets. If you were something like water would it be natural for you to get through that clasp-connection? This design is made by electrical engineers who think 2-dimensional (in terms of power) when designing electrical parts and connections (and they think production time and money).
Now...if you perfectly solder a wire from the IEC to the motherboard of the PRO it might not be THE perfect connection but sure it would be better thinking a 3-dimensional way.
