Raspberry Pi 4B platform + AK4137 design
Raspberry Pi 4B platform, quad-core 1.5GHz64-bit ARM Cortex-A72CPU, super processing power; SRC AK4137 design, can be arbitrarily converted between PCM-DSD; Jitter extremely small clock recovery circuit , So that the clock of streaming media playback reaches a very stable level.
DA_4 fully balanced decoder
Delicate notes touch every cell
AK4493 decoding chip,
This is a 123dB 768kHz/32-bit 2ch Premium DAC chip, and it is also a cost-effective chip in the 449X series, allowing you to sound on the scene.
AM_4 Pure Class A
Fully discrete fully symmetrical amp
Pure Class A, fully discrete (all circuits constructed with transistors), fully symmetrical circuit construction of the amp; better than asymmetrical circuit transient response, lower crossover distortion, every detail is full, rich and clear.
PO4 power supply unit
Independent power supply, dual configuration optional
Configuration 1: Pure DC battery configuration, using 12V 21Ah large-capacity lithium battery as power source, 8-10 hours long battery life, and the power supply environment is pure and interference-free;
Configuration 2: AC adapter power supply, linear large-capacity loop power supply, and large dynamic voltage stabilization with PO_4, which is cleaner than switching power supply mode.
