The fifth foot on the A8A has special brass parts inside, designed to further provide detailed, rich sound reproduction.Newly Designed Mechanical Structure
The symmetrical internal layout of parts and totally renewed circuit boards are designed to keep the signal paths on each board as short as possible. The new H-cross frame improves the rigidity of the receiver body and sound stability, allowing for clearer, sharper, and more transparent reproduction. Also, the newly redesigned mechanical structure contributes to avoiding the transition of vibration from the transformer to the amplifier circuit. Sound noises are reduced to improve clarity.HDR Support with HDR10+ via a Planned Future Update
HDR (high dynamic range) video provides incredible contrast, smooth tone, and rich, bright colors, giving you full, high-definition enjoyment with an exceptionally realistic and natural picture quality. HDR10+ greatly improves the dynamic range (the ratio of light to dark) of video content on a scene-by-scene (or even frame-by-frame) basis. Also, using frame-by-frame metadata, it improves the scene characteristics between bright and dark so that important detail can remain. This enables displays to reproduce images more realistically, adhering to the creator's intent. HDR10+ support will be enabled via a planned future update.4K60 with Planned Future Support for 8K60<sub>AB</sub> and 4K120<sub>AB</sub>
