Folks - I'm the Fiio M17 owner and absolutely love it with ZMF/Meze (obviously tuned with the right gain, balanced cable and DAC filter). One question though: what charger can you recommend, as have mixed feelings, seeing not much about it in the manual? Technically, it can be any QC3.0 or PD type one, but again there is a warning not to exceed certain Volts, Amps and Watts, so realistically any modern USB charger should be OK, but again they kind of warn you not to use anything more powerful than what is commonly available on the market. Realistically then, I'm looking for a charger that charges my DAP really fast, but won't damage it. Let me know what your experience is. Tks.
