If you want to drive high-impedance headphones, use the CX31993 purely as a DAC (connected to a clean USB source) and feed the 3.5mm line-out into a dedicated portable headphone amplifier (like a Topping NX series or a JDS Labs Atom) using a 3.5mm to 3.5mm interconnect. Advanced Hardware Modifications (For the DIYer)
It is highly probable that is a misinterpretation of CS51983 or a confusion with Cortex-M3 part numbers (which often follow similar naming conventions).
The has quickly established itself as the go-to chipset for ultra-budget, high-resolution USB-C DAC dongles. Offering a staggering 32-bit/384kHz PCM sampling rate and a theoretical signal-to-noise ratio ( SNR) exceeding 128dB , this tiny integrated circuit outperforms standard motherboard and smartphone audio outputs by a wide margin.
Android natively downsamples all audio to 16-bit/48kHz. To hear true high-resolution audio through your CX31993:
Because the CX31993 is naturally bright, it can make sharp IEMs (like many KZ models) sound fatiguing.
