I already have the great sound system Logitech Z-5500 which is in the living room. I was looking for a system which is similar only good "small" were in the processing and in the sound and am inevitably came across this system. The Rezesionen here have let me but be extremely unsafe. After ordering, I had actually already so resigned to the system again to send back.
But lo and behold: no humming or the like as I have it connected to the PC. A lightweight (minimally to listening) scratch when you move the volume potentiometer, but otherwise?!? Good sound and no noise.
While it is not the same as the Z-5500 but the value is very good as hoped.
