That model is so simple if not say trivial, that it still keeps a negligent name of the prototype project. We have finished that within a month or so. This toy is conventional USB DAC + balanced Headphone Amp, however, it made from the best for today components and now #9038S the only USB DAC+HPA with 550mW@16ohm, SNR -122db(A), THD .0002%@-3dbfs@32ohm, and 10g weight.
The device can operate in 4 modes:
1) Normal Mode -LED is always On, no flashing.
2) Performance Mode – LED flashing 2Hz when no signal detected, THD performance optimized for Fs 44.1-48kHz but PLL lock slower and the first-second signal is muted.
3) SE Mode– LED flashing 1Hz when no signal detected, 2nd harmonic artificially increased to emulate SE tube behavior.
4) IEM Mode, max volume limited at -15dbfs, LED is Off. In that mode 9038S ready for as low as 4ohm load.
To switch between modes you need to interrupt #9038S power during its startup when LED very fast flashing. Then next turn on #9038S will be started in the next mode(1-2-3-4-1-2-3-4.. cycling)

QUESTIONS & ANSWERSAsk a Question
how do I make the e1da work in stereo, right now it only outputs in mono
Your 2.5mm connection maybe loose, check if you plugged it securely.
The stopper should be touching the metal contact on the PDv2
