The FiiO K7 has a six-stage audio circuit with truly balanced analogue and digital sections. This helps to reduce crosstalk and reproduce the music to agreat extent, allowing you to better enjoy the purity of your music. Using the same THX AAA 788+ amplifiers as the K9 Pro, the FiiO K7 is capable of outputting 560mW into a 300Ohm load at 1% distortion. And 2000mW into 32Ohm load at 1% distortion. This ensures bot, low and high impedance headphones are powered with a plomb. And most important, it lets you experience your music at another level. The left and right channels are ach equipped with an efficient high-performance AK4493SEQ. With this DAC´s, pleasant timbre, its rich and delicate overall sound will let you rediscover your music all over again. The XMOS XUF208 decoder chip uses dual clock management to handle various formats with ease. Allowing you to easily listen to many audio formats. The RGB indication lights can display single colors as well as mixed colors, wit a unight light flow effect during power on/off or input switching. Dazzling and vidi light effects give your desk some much needed spice. Overheating, overload, DC protection system ensure that the K7 always operates at its best. So you can always enjoy a wonderful listening experience in multiple scenarios. The K7 features a powerful design, consisting of multiple independent stages. With a voltage of each stage, being regulated by low-noise LDOs. Feeding this power design in an external 12V switching power supply. All in all, the K7´s power designed to supply plentiful, clean power for an extraordinary listening experience. The high and low hardware gain levels allow you to easily adjust the FiiO K7 to handle headphones of various impedances and sensitivity, for a rich and consistent listening experience. The FiiO K7 features an all- aluminium alloy construction, carefully finished with CNC and other processes.
