#9038S Gen2


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)
