The DAC uses two ESS Sabre ES9028Q2M DAC chips, one dedicated to each channel (left/right) — a dual-mono architecture that reduces crosstalk and delivers superior stereo separation and high fidelity.
It supports high-resolution audio: PCM up to 768 kHz / 32-bit and DSD512, with full MQA decoding.
Digital inputs include USB-B, coaxial, and optical, as well as Bluetooth 4.2 with aptX.
Analog outputs are available in both balanced (XLR) and unbalanced (RCA) formats, plus a headphone output (6.3 mm jack).
It includes a built-in headphone amplifier. The 6.3 mm jack provides genuine power: over 300 mW at 32 Ω or approximately 65 mW at 150 Ω, sufficient for most headphones, including high-impedance models (recommended range: 10 Ω – 600 Ω).
Frequency response is 10 Hz–50 kHz (±1 dB), signal-to-noise ratio exceeds 115 dB, and THD+N is below 0.0005% (at the analog outputs).
I have the original box and all accessories.
The unit is in perfect condition, except for the scratches visible in the third photo.
