ES9018Q2M-CT7601 decoder DAC-V1

Overview

The headphone amplifier/DAC uses an LT3042 ultra-low noise LDO and an Epson TCXO 38.4MHz low phase noise active crystal oscillator.
For the PC, a SoundEvil exclusive player is recommended.

The 806Ω and 4.7Ω resistors near the ES9601 chip should be film resistors, and the 2.2nF capacitor should be a C0G capacitor.
The 49.9kΩ and 453kΩ resistors near the LT3042 should also be film resistors
. The crystal oscillator under the ES9018K2M can be replaced with a higher frequency 2520 package crystal oscillator, but the frequency must be greater than 38MHz.
The decoupling capacitors near the analog circuit should be 2.2uf, 4.7uf, and 1uf; do not replace them with 100nF!
