The PNP Type-DX is a premium audio device based on the Raspberry Pi 3B, featuring independent 5V, 3.3V, and 1.8V power supplies using ultra-low noise LT3045 regulators. Its BCM2837 SoC is equipped with a 0.2ppm VCTCXO oscillator for precise timing synchronization. The FifoPi Q7-based I²S FIFO reclocker incorporates low-noise 1-bit reclockers and 44.1/48kHz CCHD-957 oscillators for superior signal integrity. The ES9038Q2M dual mono DAC supports up to 384kHz PCM, native DSD512, and DoP, with AVCC, DVCC, and VCCA powered separately via LT3045 regulators. The I/V stage uses LT3045, LT3094 regulators, and Burson V6 discrete OP-AMPs for unparalleled audio quality. It operates via a ZA-Rate battery with ul
