Hi! :)

My brand new Denon M40 micro hifi system is constantly making a buzzing sound, not the low frequency (50Hz) buzz, but higher. The buzzing doesn't change with the volume setting, however it stops if the voulume is all the way down (mute). The buzzing can be heard through speakers, and headphones (more pronaunced with headphones). It doesn't matter which source I select (CD, USB, FM...). Nothing is connected to the hifi, only the speakers.

Any advice or possible cause?

Take it back to the shop and get a full refund.
