Supports MQA decoding.

The newly developed intelligent temperature compensation system (ITS) ensures that the product is always in the best performance state.

The top performance D/A chip ES9038PRO from ESS Technology.

The high-performance power supply chip ES9311, the noise of ES9311 is as low as 1uVrms, to push ES9038PRO to the limit.

XMOS XU-208, true 32bit audio processing, supports DoP and Native DSD, and reaches 32bit/768kHz and DSD512.

Ultra-low phase noise and optimized clock processing circuit are used to achieve ultra-low clock jitter.

All inputs support DSD streaming, including coaxial and optical (DoP64).

Use tempered glass display panel for higher light transmission and longer service life.

Built-in shielded, low noise power supply processing, while improving power efficiency, lower power consumption.

Specially designed discrete component linear regulated power supply and multiple low noise regulated power supplies to provide low noise power for analog circuits.

The latest Bluetooth supports LDAC, APTX / HD, SBC, AAC and the industry’s highest specification 24bit / 192kHz UAT format.

High quality gold-plated input and output jacks.

3 high-end dual op-amps OPA1612 and a lot of audio grade components are used.

1.9 inch TFT LCD display.
