Coaxial out cannot send 24 bit flac files to iBasso DB2 (ironically), 16bit works fine...
- USB OTG works partially on cheap scandisk memory stick
except for large music files (e.g. 24bit files for a long music track)...
- quite a number of flac files cannot be updated into the library
- everytime u turned on the DAP, you need to adjust the vol from 120, it wont't remember the last preferred vol...
SQ-wise, there is nothing to complain except the synergy with ASG-2 is really quite low and could not bring out the solid bass out of ASG-2 (listened using lo-gain and no EQ). (Guys, please advise on how to improve the synergy)
When listening using TG334, the synergy seems to be higher. (adding an additional amp brings no obvious benefit in this case)
Comparisons were done with a modded X3 and 901.... Note that DX50 SQ cannot touch 901 since 901 sound is true audiophile.
Once the teething problems are fixed... I really feel this is the "bang for your bucks" DAP on the market (the official AK100 killer, joking)
I suspect the teething problems can only be resolved after 4-6months.... firmware perfectionists please look elsewhere...
The design and build quality make me when to invest in mod and further tuning....
