Compressed Music Enhancer
High Slew Rate Amplifier
The slew rate measures how quickly an amplifier can respond to a rapid change of input level, which contributes to delivering a precise signal transmission and is especially effective with high resolution audio signals. This newly designed circuit achieves both a high slew rate and stable signal transmission, allowing it to handle each audio signal with precision and accuracy.
High-Quality Digital Components
Features ESS’s state of the art 32-bit SABRE PRO Premier DAC ES9026PRO. ESS’s patented 32-bit Hyper Stream, Total Harmonic Distortion (THD) compensation function works to minimize noise levels. In combination with the Yamaha original D.O.P.G. (DAC On Pure Ground) concept, which eliminates the potential difference between audio circuit stages to reduce ground noise, it dramatically enhances silence and resolution over the entire audio range for rich and expressive reproduction of even the most delicate sounds.
CRAFTSMANSHIP
Anti-Resonance Technology Wedge

The newly designed Anti Resonance Technology (A.R.T.) Wedge is a fifth foot in the front-and-center of the chassis unit base. Together with double bottom structure, it dampens much more vibrations from the power transformer, power transistors and heat sinks, as well as vibrations that might be caused by the sound from the speakers — providing dynamic sound and focused, accurate reproduction. A8A’s fifth foot has special brass parts inside which continue to provide further detailed and richer sound reproduction.
Newly Designed Mechanical Structure
MOVIES AND GAMES LIKE NEVER BEFORE
HDR and HDR10+*
HDR10+ signals not only dynamic range (the ratio of light to dark) of video content on a scene-by-scene (or even frame-by-frame) basis, it also provides, in a small amount of metadata, 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.
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+ is available via a future update

8K/60Hz, 4K/120Hz
Supports end-to-end 8K/4K resolutions and higher refresh rate solutions with a single upgraded cable for seamless integration within the HDMI eco-system.8K delivers a super-immersive viewing experience with 2x the horizontal and vertical resolution of 4K, and 4 times as many pixels; and combined with 60Hz refresh rate enables smooth and sharp viewing of content with high-speed action. 4K/120Hz enables ultra-fast motion UHD images to be crisp and razor sharp; allowing sports, action movies, high-performance gaming and VR to benefit significantly.

Enhanced Media and Gaming (ALLM, VRR, QMS, QFT)*

Enhanced media and gaming features ensure an added level of smooth and seamless motion and transitions for gaming, movies and video. They include: Auto Low Latency Mode (ALLM), which enables the ideal latency setting to automatically be set allowing for smooth, lag-free and uninterrupted viewing and interactivity; Variable Refresh Rate (VRR), which reduces or eliminates lag, stutter and frame tearing for more fluid and detailed gameplay; Quick Media Switching (QMS) for movies and video, which eliminates the delay that can result in blank frames before content is displayed; and Quick Frame Transport (QFT), which reduces latency for smoother, no-lag gaming and real-time interactive virtual reality.
* These features are available via a future update
DESIGNED FOR YOUR SPACE
YPAO™ – R.S.C. (with 3D, Multipoint Measurement and 64-bit High Precision EQ)
