Amplifier score is based on power ratings, minimum impedance load, power supply, transformer type, total harmonic distortion, damping factor, signal to noise ratio and other small details. Audio score depends on the number of channels, front wide channel support, maximum channel processing, support of audio formats, DAC specifications, room calibration algorithm... Video score is based on HDR, Dolby Vision and video signal passthrough and upscaling, analog to HDMI upconversion. Connectivity score is defined from all wired and wireless inputs and outputs, internet and bluetooth connections, HEOS, SONOS and others. Multizone score depends on the number of zones with their outputs. Radio score is evaluated form digital radio support and analog tuner with its frequency range, signal to noise ratio, harmonic distortion...
