FiiO K7 - Headphone Amplifier with Built-In Digital-to-Analog Converter

The K7 features a six-level sound circuit with truly balanced analog and digital sections, which helps reduce crosstalk and accurately reproduce music.

High-Quality Balanced Amplification

The K7 is equipped with the same THX AAA 788+ amplifiers as the K9 PRO, capable of delivering 560mW of power to a 300-ohm load at 1% distortion, as well as 2000mW to a 32-ohm load at 1% distortion. This ensures optimal performance for headphones with a wide range of impedance and, most importantly, allows you to experience the musicality that will touch your heart.

Rich and Delicate Sound

The left and right channels are equipped with the efficient high-performance AK4493SEQ DAC. With the accurate reproduction of the timbre and its rich and delicate sound, you will rediscover your music.

High-Precision Decoding

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

RGB Indication

The RGB indicators are capable of displaying individual and mixed colors with a unique light flow effect when power is turned on/off or when switching input signals. The dazzling light effects will add a much-needed touch of sophistication to your desk.

Advanced Device Protection System

Protection systems against overheating, overload, and short circuit ensure that the K7 always performs at its best, so you can enjoy excellent listening and not worry about the device during power issues.

High-Quality Power Supply

The K7 has a power supply design consisting of multiple independent cascades, with the voltage of each cascade regulated by low-noise LDOS. This design is powered by an external 12V power source. Overall, the power supply design of the K7 ensures abundant and clean power for quality listening.

Multifunctional Control

One toggle switch controls the selection between 4 different inputs with a smooth light effect indicating when the input is switched and ready to use.

2 Amplification Levels

High and low levels of hardware amplification allow for easy customization of the K7 for headphones with different impedance and sensitivity, providing rich and stable listening.

Design

The K7 features a fully aluminum alloy construction, meticulously processed using CNC machines and other technological processing methods. Its elegant black color is perfectly complemented by gold THX and Hi-Res Audio logo inserts, enhanced by a burst of color from the RGB backlighting for a luxurious appearance.

Power output

This is the useful power developed by the amplifier in the load resistance. Amplifiers are usually characterized by the highest power that can be obtained at the output, provided that the distortion does not exceed the specified permissible value. This power is called the output power of the amplifier.
