I have purchased that device on the advice of my friend at Switchonshop. I didn`t fully understood all existing settings but ARM Cortex-A53 processor easily plays 4K content at 60 fps and does not create an excessive load on the network. Even when playing compressed audio, HD media player delivers clear surround sound with built - in support for eight-channel Dolby Digital Plus audio and provides Hi-Fi sound. I have some questions about MAG please write me if you can help.
