Product Overview
Newly Designed Frame Beam Base Chassis
The chassis of the ES model has been fundamentally revised: the overall thickness has been increased for improved rigidity, and the structures of the transformer base and other weight-bearing parts have also been redesigned to improve the instantaneous power and crispness of the sound, when compared to a conventional chassis.
Offset Screw Position Foot
Designed with an offset screw position to both eliminate the resonance point and avoid frequency-specific, vibration-inducing resonance transmission to and from the transformer, the foot also contains additional ribs for increased rigidity and improved resonance control.
Redeveloped digital section
The new digital section enables all signal processing to be performed on a single chip while also providing lower impedance, increased capacitance, and better stability.
New DAC enables 32-bit operations
Digital PCM signal input is processed at 32-bit and converted to analogue by the DAC, while DSD signal input during direct mode is natively input to the DAC and converted to an analog signal.
Improved analogue power for DAC
The DAC analogue power supply uses a low-noise power supply IC to ensure that hi-fidelity performance is achieved
Buffer amp for DAC
New DAC analogue output filter circuit was designed utilizing a JFET and op-amp improvement in noise floor. The phase rotation was shifted to a higher frequency, expanding the bandwidth and improving sound clarity for wide-bandwidth sources like high-resolution audio.
Sony exclusive integrated circuit
A Sony-exclusive integrated circuit was developed to improve all amplification function on the STR-AZ3000ES. The pre-amp is independently connected to each individual amplifier channel, improving channel separation and reducing internal interference over more traditional cascading designs.
Refreshed Digital Circuit Board
Metal ES-grade frames both secure the circuit board and protect it from vibration caused by speaker sound pressure. The varying fin length of the integrated heat sink reduces audible resonance uniformity while also shielding delicate circuitry from noise.
Lead-free ES solder
Applying years of sound engineering and testing experience, Sony has developed an ES-grade solder. A high-purity tin base combines with small amounts of specially chosen metal elements for a unique alloy mix that enables a quality signal and exceptional sound.
Fine Sound Resistor
The special resistance materials and structure, pure copper has been used in the electrodes to achieve high volumes of data with rich, vivid audio quality.
8K and 4K/120 HDMI Connectivity
Enjoy the latest HDMI technology with support for 8K & 4K/120 video sources. Equipped with four 8K HDMI inputs and two outputs the STR-AZ3000ES is capable of delivering the most stunning picture quality and amazing clarity.
HDMI 2.1
While enabling higher-quality video output and reduced latency from input devices like game consoles, HDMI 2.1 also provides support for Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR).
Supports Dolby Vision, HDR10, and Hybrid Log Gamma, and IMAX Enhanced
Enjoy dynamic, realistic picture quality with support for the leading HDR formats, including Dolby Vision, HDR10, Hybrid Log Gamma, and IMAX Enhanced.
