High Resolution DAC

The Ayazi was conceived, designed and sonically fine-tuned by hi-end enthusiasts and the team’s professional engineer, aiming to bring out the musical magic encoded in the numbers stored within digital medium.
It’s a compact, high-end sounding, affordable standalone DAC which combines the most proven and sophisticated design principles and techniques for digital audio reproduction. Technologically, it uses state-of-the-art components, resulting in class-leading specifications, outstanding technical measurements and exceptional sonic performance.

Ayazi offers support for up to24-bit/384kHz audio via USB, and 24-bit/192kHz over S/PDIF. DSD64 and DSD128 playback is supported via USB (all via on the fly software conversion 352.8/24 ). It also has a handy switch to easily move between coax and USB digital inputs.

The device features a Class 2 USB from CMEDIA input with electrostatic protection. This has been achieved using a technique which allows for enhanced data rates of up to 384kHz; the input is driverless on Apple devices and with drivers for Windows devices.

Cmedia drivers key features:

• Playback feedback endpoints to control the data transmission accuracy and to maximize the audio quality
• XearT Pro
• Supports ASIO2.2 driver

Unlike conventional sigma-delta implementation, the ESS Sabre converters incorporate innovative patented time domain jitter eliminator technology to deliver spectacular music free from clock jitter common in digital audio systems.

Ayazi's circuit also uses Crystek's top end CCHD-957 HCMOS clock oscillator designed specifically for HD Audio. It features a typical low close-in phase noise of -100 dBc/Hz @ 10 Hz offset and a noise floor of -169 dBc/Hz. With this extreme low phase noise & jitter performance, you will definitely hear the difference: wide dynamic range, ultra-low distortion, accurate sound stage, and jitter-free music clarity.

Ayazi DAC key features:

• Coax, and USB digital inputs, switchable from front panel
• Electrostatic protected Class 2 USB input up to 384kHz
