Power consumption when idle

[mamo944]

JonnySix or someone else with a watt meter, could you measure how much power they consume in various states (off, idle, and playing)? Would you also specify whether it is for the white or silver and any other variables? This is an important aspect of my decision about them and I can't find the power consumption information elsewhere so thanks for providing it here.

I tried to switch off the units by holding the power button for 5 seconds like trashken suggested but that doesn't change anything. 20w continous power consumption per unit remains when not in use.
During listening it can go above 80w what of course is not a problem.
