I have a soundtouch 300 hooked up to an x930e, accompanied by an acoustimass 300. Whenever there is a sudden light sound such as someone setting something down on a table, footsteps, or sometimes in voices, the sound comes through almost as if it is being filtered to sound robotic, like something out of a sci fi movie. I read a 6 page post on here where people have been having the same issue since the start of the year. It appeared as if Bose thought the updates should fix it. I upgraded to V17 right out of the box because the issue was very apparent. The people on said post seemed to be returning their units.
