Canary II PCM768Khz  DAC Class A headphone amplifier

Product Detail

DA-ART Canary II

The original YULONG DA-ART Canary was an instant hit, it offers high performance at a relatively low price and is widely received as the “Best Bang for Your Buck” product by reviewers and users.   We appreciate the recognition but we want to make it better. The Canary II received a major upgrade on the digital audio circuit and this enhanced the digital audio capability as well as the quality of digital audio data significantly.   The Canary II employs the latest ES9038Q2M DAC chipset and XMOS XU208 solution, and we replaced the low-cost MCU with our powerful FPGA and Femtoclock PLL for synchronization. It is one of the very few, if not the only, FPGA based All-in-OnDAC/Pre/Amplifier at this price point. We fine-tuned the well-received high power Class A headphone amplifier and 15V fully symmetric power supply, and keep the seamless aluminum chassis,making it a real bargain for Personal Audio users.

The key features of Canary II are:

        Enhance quality of digital signal, optimize data integrity and de-jitter through proprietary FPGA with Femtoclock PLL synchronization.

        Outstanding digital audio capability:

o   Design around ES9038Q2M DAC with Class-leading 32Bit/768kHz and DSD512 decoding

o   Widely recognized XMOS XU208 solution with customized (with license) Thesycon driver to enhance sound quality and stability.

o   All inputs interfaces support DoP64 and DoP128, USB input interface supports Native DSD64/128/256/512 additionally.

        State-of-the-art analogue implementation:

o   Fully discrete, DC coupled JFET input Class A headphone amplification for impressive driving and handling capability.

        All-in-one design with comprehensive connectivity:

o   Choice of 6.35mm headphone output and RCA preamp output, can handle16Ω-600Ω headphones and active speakers satisfactory.

o   USB Audio supports MS Windows, macOS, Linux, Android and iOS.

        Outstanding power management within compact space: independently regulated two channels power supply with ultra-low-noise LDOs,

           CLC power filtering with high power conversion technology.

        Seamless, compact and sleek aluminum chassis, 18K gold plated control panel and high precision probably-damped volume knob.

        External universal voltage 12V Power supply.
