Firestone Audio BlackKeyUSB DAC 96k
PC is one of the most common ways to enjoy the music, but the quality of its built-in audio capability can not be satisfying with your growing passion to music. The options on the current market are either the internal sound card which couldn't cater to the needs of laptop or tablet PC users, or the external sound card which is too clumsy to carry around. The miniature BlackKey has the ability to elevate the music quality, making you feel like in the abyss of melody!
