Singxer SDA-2 Advanced Version DAC/Amp
High-Performance Decoding & Amplification
New from Singxer, the SDA-2 Advanced Version delivers certified Hi-Fi audio with cutting-edge circuitry and premium components. Equipped with a Crystek CCHD-575 femtosecond crystal oscillator USB clock, the SDA-2 Advanced Version comes equipped with XMOS's latest xCORE-200 series chip for USB audio. On the DAC side, it features AKM’s flagship AK4497EQ DAC chip and supports PCM decoding up to 384 kilohertz, as well as native DSD decoding up to DSD512. For the amp, the SDA-2 adopts a four-way fully balanced design with an independent, discrete class-A amp drive circuit. To fit any setup, it’s outfitted with SPDIF coaxial and AES balanced inputs, an analog XLR balanced output, and an analog RCA output.
Note: This run is for the SDA-2 Advanced Version.
