Keep the CX31993 paired with low-impedance, high-sensitivity headphones (under 150 Ω).
The CX31993 is not a bad chip; it is a great chip trapped behind bad documentation and lazy OEM integration. With these fixes, your $10 dongle will outperform most $50 "audiophile" portable DACs.
To help tailor these optimization steps to your specific audio setup, tell me:
