bro, you need better knowledge.. because you are misleading some information.. please research before telling to people.. Coaxial cable is for digital output, it can handle upto 5.1 but not high quality as spdif Optical cable and hdmi.. Also you mentioned, that power adapter not needed if HDMI ARC connected, is that true? please check and let the viewers know..
