  High quality: HDMI transmits the audio far and wide to the amplifier in pure digital connections are more prone to loss due to wiring from audio conditioning equipment and other electronics. Compared with SPDIF connection, HDMI has greater bandwidth, allowing it to support the latest lossless audio formats.
  Ease of use: HDMI integrates video and multi-channel audio in a single cable, thereby eliminating the cost, complexity and confusion of multiple cables used in current A/V systems. 
  High intelligence: HDMI supports two-way communication between audio sources and audio conditioning devices, supporting new features such as automatic configuration and one-touch playback.
