Have bought the receiver, because I had tired of the tangles, PS3, LG Blue Ray player and Sky TV tuner for. Three HDMI's and an optical cable to the TV, which unfortunately then also not given the sound of the new generation back to my AIWA receiver (only partially DTS and Dolby Digital). Thus, needed a solution and that is the STR-DH520 7.1. Now plug the HDMI Use the equipment in the new receiver, which gives the sound of the latest standards, and again there is only one HDMI cable to your TV needed.
My old Magnat speaker system with subwoofer I use on and the receiver is a class sound again. The automatic calibration of the boxes is quick and easy when you have to be incorporated into the operating instructions and in the display of the receiver.
All in all this equipment for the price ..... just great
