But what bothers me very: it is not specified in the product description the Wolfson WM8805 DAC chip installed. This was a decisive factor for the purchase of Fiio D03K for me. Installed is a Cirrus Logic 8416, which applies, according to specialist forums in comparison with the Wolfson WM8805 chip as inferior. Cirrus chips you get in 10 cheaper DA converters.
Since not the advertised quality Wolfson chip is installed, there is of me only 2/5 stars, although the product works well in itself.
