FiiO K7 USB DAC/Headphone Amplifier As a bonus, I'm including an AudioQuest Carbon USB cable. Used only indoors. Usage frequency was not high, and there are no noticeable scratches or stains, so it's in overall clean condition. Operation has been confirmed, and there are no issues. It has high output and driving power, easily driving both open-back and closed-back headphones. It also has a high sense of sound separation and resolution, making it the perfect DAC/amp for a desktop environment.
