220 power supply

[Confused]

So the first question you can ask, but you mean to know something else. Especially the graphics in the last showthread shown by Confused says a lot. But not everything. Everybody should start with the beginning and I don't ever see such discussions about it: the 4k power needed by the Devialet is much more easily delivered in an European situation then in the USA. Like the best kitchen appliances from Germany (Miele) cannot be sold in New York city because the power which the houses can be entered (the mains) are too low. (380V-20A maximum in the Netherlands, Europe when you buy it into your house; 230V-16 A standard. Almost nobody pays for the extra mains here). If you want a Devialet to sound fabulous you need a minimum of 4.000 Watts of power from the mains. Continuous and in milliseconds as well. My entrance is 230Volts by 20Ampere= 4.600 Watts. 2 times only for the music.
What (or Watt) are yours? All over USA 110V? And the rest of the world? Devialet is build in and for the Europe situation. Especially current needs extremely bulky cables (in silver-expensive). My VandenHull mains cable costs 420 euro pro meter and that's only for 230Volts...... To reach the same effect at 110V you need more then 2 times the diameter.....

And another factor are the mains plugs: I once read on a Japanese website (Furutech) that the mains plugs in different countries can handle different powers. My conclusion is: I think that the Devialet is not the limiting factor here; the different mains inputs in the different countries are. And the investment on your mains entrance is very important with such a powerfull amplifier. It's a D class as well: switching by electronics: so the power of the amplifier is dependent on the mains. Very.

Perhaps something to think about...?

From Devialet's website:

The control loop is ultra-quick and particularly well suited to audio engineering. Expert Pro systems can instantly shift from 0 to 4000 Watts while sustaining an average running power of 1200W. Output voltage is variable by a factor of 8 from +/- 10V to +/-80V and constantly changes to minimize overall thermal dissipation.

A load balancing controller ensures even load sharing between reservoir capacities across different power rails, doubling the available energy supply.
Power supply relies on a central transformer based on planar technology. It serves two purposes: spreading energy in packets and ensuring the electrical safety of the product by isolating the hazardous areas. Compact and perfectly symmetrical, the central transformer is far superior to traditional solutions in terms of efficiency and primary/secondary pollution.

Power supply is unaffected by the mains and runs silently with remarkably low electromagnetic disturbance. It is universal and compliant with all power grid supplies: 90-240Vac – 50/60Hz. Driven by a microprocessor, power supply is automatically protected from anomalies including surges, dips and overloads. On a practical level, functional range is stretched out even further to 50 - 270Vac ~ 40/70 Hz, making your Expert Pro available for use anywhere in the world.


The above text refers to the power supplies maximum capability.  So with the amplifier running at its' absolute maximum, the power supply will need no more than 1200w continuously, which is about 5 amps in the UK or Europe, and even with 110v in the USA is less than 11 amps.  To be clear, these are maximums, with most domestic listening the figures will be considerably lower, probably nearer the 1 amp or so level.  Consider that most speakers will only cope with 100w to 400w continuously.  If you did manage to run 1200w into your speakers on a continuous basis then melted voice coils are more likely to be your problem that the amplifier demanding too much current.

4 kw is a LOT of power, it is the kind of power that something like an electric oven, a patio heater, or large room heater would use.  Devialet's get hot, but not hot enough to heat your living room in winter or roast a whole chicken.  

So looking at the numbers, I would say a Devialet user in the USA with 110v is likely to get exactly the same performance as one in Europe, all other things being equal.
