Is this normal, and if not, can it be corrected?
Perhaps your interconnects are picking up RF interference. Do you have all of your wiring nice and neat, or does the back of the rack look like a rats nest? Keep your power cords away from the other cables, and if they must cross each other, cross them at 90 degrees. Do not run them side by side.
Start with only the bare minimum components hooked up. Example: nothing hooked up...listen as volume is increased. Hook up one piece, like the DVD player...listen as volume is increased. Continue till something good happens.
A "hum" makes me think ground loop...Hiss/fuzz
makes me think RF interference. Ground loop issues can be fixed, sometimes by way of a simple "ground lift" switch like the one on the rear of my processor. Hum/ground loop...plug everything into the same circuit. This is where a good power conditioner comes in handy.
In my experience, sometimes what you are hearing is the noise floor of the equipment, and there is really nothing you can do but live with it. Awful isn't it. I can't speak for or against any manufacturer, but "money does buy you love". A well built component has the potential of running quiet. If you have to put your ear pretty close to the spkr to hear the buzz, it may be something you can live with, being that it will be inaudible while music is playing.
