ES A/V Receiver: Elevated performance for all
Renowned ES Quality

Redesigned with build quality in mind
Newly Designed Frame Beam Base Chassis
Offset Screw Position Foot
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.
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
New DAC enables 32-bit operations
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.
Digital PCM signal input is processed at 32-bit and converted to analog by the DAC, while DSD signal input during direct mode is natively input to the DAC and converted to an analog signal.
Improved analog power for DAC
Buffer amp for DAC
The DAC analog power supply uses a low- noise power supply IC to ensure that hi-fidelity performance is achieved
A new DAC analog 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
Refreshed Digital Circuit Board
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.
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.
