Yesterday saw the poorly draped covers properly pulled off the Denon DJ SC3900. This one has had more pre-release leaks and sneak peeks than just about anything in recent memory. But enough press teasing and game playing - I've had one for a few days, and for this all too brief time have been prodding it into submission. What follows is not a review, but more of an overview, with my eye lingering on the new gubbins.
