FiiO K7, solidity and rhythm for your music

The FiiO K7 is the new desktop headphone amplifier/DAC with a truly balanced structure.

It features THX AAA788+ amplifier technology and AK4493s dual DACs and multiple intelligent protection systems. Its elegant design and the integration of a volume wheel with RGB light, mark the lines of a perfect device for your headphones.

6-stage circuit

The FiiO K7 has a 6-stage audio circuit with truly balanced analog and digital sections, which helps reduce crosstalk and reproduce detail, allowing you to enjoy the full purity of your favorite tracks.

High quality balanced amplification

Utilizing the same THX AAA788+ amplifiers as the K9 PRO, the K7 is capable of generating 560mW into a 300 Ohms load with 1% distortion and 2000mW into a 32 Ohms load with 1% distortion. This ensures that both low and high impedance headphones perform with aplomb and, more importantly, allows you to experience musicality that will touch your heart.

Rich and delicate sound

The left and right channels are equipped with an efficient, high-performance AK4493SEQ. With the pleasant timbre of this DAC, its overall rich and delicate sound will allow you to rediscover your music.

High decoding capacity

The XMOS XUF208 decoder chip uses dual clock management to handle various music formats with ease, allowing you to easily listen to many audio formats.

RGB indicator lights

The RGB indicator lights are capable of displaying single colors as well as mixed colors, with a unique light flow effect during on/off or input switching. The light effects are vivid and dazzling.

Multiple intelligent protection systems

Overheating, overload and DC protection systems ensure that the K7 always performs at its best, so you can always enjoy a wonderful listening experience in multiple scenarios.

Consistent inside and out

The FiiO K7 features a power design consisting of multiple independent stages, with each stage's voltage regulated by low-noise LDO. The external 12 external switching power supply chases power made to deliver abundant, clean energy for an extraordinary listening experience.

Variety of inputs and outputs

The FiiO K7 contains USB, optical, coaxial and RCA inputs. The outputs are single-ended 6.35mm and balanced 4.4mm for full detail no matter which headphone you use.

A switch controls switching between the 4 different ones, with a flowing light effect to indicate the input change.

Two gain levels

High and low hardware gain levels allow you to easily adjust the K7 to drive headphones of various impedances and sensitivities for a rich and consistent listening experience.

Elegant look and quality construction

The K7 features an aluminum alloy construction, carefully finished with CNC and other processes. Its sleek black color is perfectly complemented by the gold accents of the THX and Hi-Res Audio badges topped off with a touch of color from the RGB lights for a vivid appearance.

The device features a small design that measures only 55mm thick and takes up less than 1/3 of an A4-size sheet of paper.

Precisely adjusted volume

Thanks to ADC curve reconstruction, experience 112 smooth steps of adjustable volume without channel imbalance or noise, ensuring that every note is faithfully reproduced.

Me gusta todo en este fiio K7

Me gusta todo en este fiio K7, viene a sustituir un magnífico K3 comprado en febrero de 2019 que sigue funcionando como el primer día, razón por la que dolía cambiarlo. Después de llegar (rápido y organizado Correos) en un ratito estaba listo, instalé el Controlador FiiO USB DAC v5.58., conexión a CPU por USB y a los Kanto por RCA y a sonar maravilla. La sorpresa fue poder mantener mi k3 y aprovechar las dos salidas de auriculares extras, incluso la conexión óptica con los Kanto. No se estorban entre sí. La apariencia de este juguete es fascinante, el aro de luz, la fortaleza que despide y la elegante proporción lo hacen bello, y ya se sabe que el mundo si se salva, se salva por la belleza.
