I'm definitely gonna try that (move it away, quoted the wrong post...), plus, I purchased some ferrite beads that you can wrap around the cables in different sizes, and I'm going to put some around evey cable to see if it helps. (You can find good one on a famous online shop, and it's very cheap.) Other than that, the sound is absolutely fantastic on this 2.1 kit. The bass is so much better than on my old Altec Lansing VS2121, on which the sub does not only restitute bass, but goes higher and reproduces some of the lower pitched instruments in a song!

Just bought it in France, got it two days ago, and yes, they are noisy. When they enter sleep mode, the sound goes away. As soon as they exit sleep mode, the hum comes back, in the subwoofer AND the satellites. Must be some kind of interference from the mains. It can not be a ground loop as the power wire is... 2 wires! No ground wire like a PC cord for example. I haven't tried putting them in another room to see if it makes a difference yet.
