1. Native hard solution DSD

2. Fully balanced 7 dual operational amplifiers, with balanced XLR output and RCA single end output, and 4 single operational amplifiers are used for the ear amplifier

3. Dual chip dsd1792 design, each chip is connected in parallel as one channel, and the software is controlled in mono mode to improve the dynamic and signal-to-noise ratio

4. Support XMOS sub card (or Italian amanero scheme sub card), plug and unplug, play PCM and DSD with XMOS sub card, and automatically identify and decode them

5. Ak4118 with low jetter is used for coaxial, optical fiber and Bluetooth receiving chips

6. Use two groups of analog power supply - maranz CD-7 voltage stabilizing circuit, use field effect transistor as constant current and Darlington tube as adjusting tube, with sound resistance, stable voltage, strong load capacity and large output current

7. Assemble with fever grade parts to ensure good reliability and sound quality

8. Built in fully balanced earphone. The earphone is powered by a separate transformer, with good dynamics and large thrust

9. The built-in aptx Bluetooth module supports lossless playback of aptx and aptx-ll. Bluetooth is decoded as coaxial input to ak4118

10. Standard size all aluminum case, beautiful and easy to match with other equipment
