Dual AK4497S Chips
- Flagship-grade DACs from AKM's "VELVET SOUND" series, delivering ultra-low distortion and wide dynamic range.
- Supports 32-bit/768kHz PCM, DSD512, and MQA decoding.
3.93-inch Color Screen
With a larger color screen, combined with a custom Android 12 build that features a custom portrait display system, the display is clear and easy toread. Interacting with the device directly is intuitive, so that it is easy to handle various operations right out of the box.
Powerful Amplification
- Class-AB balanced amplifier with 3,000mW per channel (balanced output), capable of driving high-impedance headphones.
- Features OP and transistor current-boost design with Onsemi MJE243G/253G pairs for high-current output.
Advanced Circuit Design
- Triple-PCB layout (separate digital, analog, and power boards) to minimize interference.
- Fully balanced signal path from DAC to amplifier for enhanced channel separation.
Flexible Connectivity
The Gigabit Ethernet port supports fast and stable wired datatransmissions, while the AP6256 Wi-Fi module supports 2.4Gand 5G band wireless networks as another way to stablytransmit lossless audio.
