Product Description

FiiO K5 Pro Desktop Headphone Amplifier and DAC acts as a bridge that allows your computer, speakers and headphones to work together to experience truly realistic details.

Stronger decoding

In the K5 Pro, clock management is improved and overall decoding performance is excellent. This is due to the XMOS XUF208 decoding chip with an all-new clock matching management system granting unprecedented capabilities that support decoding up to a sample rate of 768kHz and hardware native DSD decoding.

Coaxial and digital input

No matter what audio equipment you use, digital audio inherently has advantages in integrity and fidelity of signals transmitted. The K5 Pro allows you to take advantage of digital audio with optical and coaxial inputs supporting up to 192kHz inputs, convenient for connecting various music players and digital interfaces.

Next generation DAC

The K5 Pro achieves new heights in sound quality thanks to the high-performance AKM AK4493 DAC with 32-bit processing and Velvet Sound technology, along with the 768kHz and DSD XMOS USB decoding chip. With the left and right audio channels being independently handled and fully differential audio output, FiiO K5 Pro has such a high level of resolution, you will hear details you never noticed before.

Specially designed architecture

When it comes to amplification, the K5 Pro has generous space to fit and package the necessary components for exceptional analogue amplification. It packs a four-level audio circuit capable of providing extraordinary audio fidelity in its class: second order LPF + analogue volume adjustment + voltage amplification + current drive. Each part of the amplification circuit works perfectly together in harmony for excellent dynamic range and higher sound resolution.

Utterly precise volume control

The NJRC NW1195A analogue volume adjustment chip features an ultra-low output noise of -118dB and is able to adjust volume by 0.5dB per step. When this is paired with the combination of the flagship TI TPA6120 op-amp and the OPA1642 JFET op-amp, the K5 Pro provides wonderfully smooth yet high resolution sound.

Secure, robust power supply

The K5 Pro uses a DC 15 external power supply designed specifically to minimise noise. The incoming DC power is filtered with secondary power supply, which then independently supplies power to the amplification part of the audio circuit and the rest of the circuit. This effectively suppresses ripple and minimises crosstalk between the two major sections of the circuit for a quieter, more stable power supply. This results in outstanding sound from the precisely designed high performance audio architecture.

ADC volume adjustment

Through reconstruction of the ADC curve, the K5 Pro’s volume control allows you to smoothly adjust volume at extremely fine increments without any undesirable noise nor with any channel imbalances. With the K5 Pro, you can comfortably use various headphones with any level of sensitivity.

Gain control for precise sound

Both the input selection and gain are controlled by tactile toggle switches, which are clearly labelled so you can easily control your music. Low, medium and high gain-levels enable you to use the K5 Pro with almost any headphones at comfortable volume levels. A purely hardware gain circuit is used at low gain, with unaffected and uncompromised dynamic range and over all audio fidelity.

Finely textured all-aluminium body

The all-aluminium body is repeatedly polished with CNC and is then carefully finished with anodising and fine sandblasting creating a smooth yet finely textured shell. The K5 Pro is a compact, robust unit that doesn’t take up much space, perfect for your desktop.

Powerful headphone amplification

The carefully tuned feedforward amplifier circuit design increases the power output of up to 1.5 W under a 32Ω load, and up to 20Vpp at 300Ω. The K5 Pro easily handles any low or high impedance headphones.

RCA line high quality output

Alongside a wide variety of digital inputs, K5 Pro also features a traditional analogue RCA line-in. This is not only more robust and less prone to breakage than a 3.5mm line-in, it also has better resolution. The RCA line-out signal is adjustable up to a maximum of 2Vrms, so K5 Pro can be used with a variety of active speakers and external amplifiers.
