Sony's STR-DE345 is Dolby Digital "ready" and has some impressive features to match. The perfect source component for this receiver is a DVD player with a built-in Dolby Digital and/or DTS processor. Simply connect the 5.1 analog audio outputs (front left, front right, center, surround left, surround right, and subwoofer) into the 5.1 channel input panel on the back of the receiver, and you've got a Digital Home Theater.
