"Surprisingly open sound and large dynamic range for such a small box. The sound coming from it is with a lot of details especially in mid and high range and even with such precise reproduction. Everything is still so natural. I would like to say that Donald DAC can compare with much (read: much much) more expensive DAC converters. Congratulations !!! "

Just try it! No needs for other headphone DAC/Amp anymore!
