Hello Fiiophiles. I came to know fiio when I was searching for an solution for low volume of my android phone. I came across Fiio A1 in 2015 Very good improwin the sound quality and overall volume of the phone. Then I came across high resolution audio. And then I realized about the concept of DAC. As I already have experienced Fiio. So I went ahead bought fiio q1mk2 and e10k Both completely brilliant. Apart from this I posted some short reviews for the same.
