2003 9-3 engine vibration

I am experiencing an engine vibration throughout the rev range, that feels like buzzing. It is not related to wheel/tires/drive train. I was thinking worn engine or exhaust mount, but can't find anything amiss. The car has 47k miles on it. Sometimes the vibration has a beat frequency, in other words, it increases and decreases in amplitude as though two vibrations are going in and out of phase.
I read that these engines have two balance shafts. Could there be a problem there? Or is this just "They all do that" kind of thing.
