You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).
If you need to return an item, simply login to your account, view the order using the "Complete Orders" link under the My Account menu and click the Return Item(s) button. We'll notify you via e-mail of your refund once we've received and processed the returned item.
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 transmissions to and from the transformer, the foot also contains additional ribs for increased rigidity and improved resonance control.
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 circuity from noise.
New DAC enables 32-bit operations
Digital PCM signal inputs 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 converted to analog signal.
Improved analog power for DAC
The DAC analog power supply uses a low-noise power supply IC to ensure that hi-fidelity performance is achieved.
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.
Buffer amp for DAC
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
A Sony-exclusive integrated circuit was developed to improve all amplification function on the STR-AZ5000ES. The pre-amp is independently connected to each individual amplifier channel, improving channel separation and reducing internal interference over more traditional cascading designs.
