Whats a Pure Digital Audio System ?

Pure digital systems are digital amplifiers with digital inputs being fed by digital source material from the digital output from a DVD ,CD Player, Satellite Receiver or Cable Box. In pure digital systems the audio signal is always kept in the digital form, so there is no degradation on the signals as it goes through each stage of the various pieces of electronic equipment in its path between the source to the Loudspeaker. Digital signals have no degradation effect when passing through electronic components as do the fragile Analog signals.
