K15 not only streamer, DAC, and amplifier, then, but a true listening center, capable of handling digital and analog sources.

The architecture is fully balanced, taking advantage of the dual-differential DAC pair, with separate internal organization (circuitry divided into three separate boards-digital, analog, and power supply) to minimize interference and crosstalk, with digital and analog sections having independent power lines. The user interface, as well as in enclosure and front panel organization, are borrowed from its big brother K17, and thus 3.93-inch color monitor, with some knobs giving the machine a vaguely vintage look. Five gain levels dedicated to headphone listening can be selected, with 6.3 mm headphone, balanced 4.4 mm and XLR. outputs. The FiiO K15 thus stands to become a reference for those seeking a universal audio hub, capable of uncompromisingly integrating a passion for analog with the potential of digital. We&#8217;ll see when it becomes available for sale on Amazon.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>FiiO K15, DAC, preamplifier, headphone amplifier debuts July 19 at Canjam in London.
