The FiiO K19 is FiiO's new top-of-the-range desktop amplifier/DAC. For the first time in a device of these characteristics, a display screen is included in a unibody and ultra-thin shockproof construction.

Its 8000mW output power and its ES9039SPRO x 2 8-channel DAC combine to deliver maximum sonic definition and the ability to drive demanding headphones. 

The whole set is joined by a high-precision lossless PEQ amplifier and 31 bands and components developed to the millimeter to make your musical listening an unparalleled experience. Make way for the senses with the new FiiO K19!

The FiiO K19 features DEL technology and, thanks to its patented algorithms, it can apply various audio effects such as dynamic range compression or dynamic range enhancement. It also has advanced limiter functions.

With its high-precision lossless 31-band adjustable PEQ, there is no need for sample rate conversion as it supports direct adjustment of 44.1k-192k PCM signals. 

In addition, thanks to the K19's preset configuration, you can import and export your customizations and share it with other users. 

For the first time in a FiiO device, the internal amplifier uses an ADI ADSP-21565 DSP chip with the SHARC+ core backed by a custom ultra-low phase noise femtosecond crystal oscillator. 

The DSP chip features a high clock frequency of 800MHz and is capable of performing double precision calculations. The chip also guarantees that the signals are distortion-free and of high quality, protecting the operation of the K19 and other devices and headphones. 

Inside the FiiO K19 is a pair of new ES9039SPRO 8-channel DAC chips with fourth-generation 32-bit HyperStream architecture. They are capable of achieving ultra-high dynamic range with ultra-low noise.

These DAC chips allow the K19 to produce clearer, richer audio full of details.

• THD+N: -122dB
• DNR: 132dB

The FiiO K19 features a new headphone amplifier design consisting of an 8-channel THX AAA788+ architecture running in parallel and backed by a high-voltage power supply.

These THX chips are connected in parallel using 2 x 2 groups to form a fully balanced 4-channel amplification system. 

The result is improved transients and a high power output of 8000mW + 8000mW with a 32 Ohms load.

With a completely renewed style, the FiiO K19 has been manufactured on a die-cast aluminum alloy body for an impeccable design. The body is carefully polished using a multi-axis CNC machine for flagship quality.

The aluminum alloy body is not only thin, but also shock-resistant.

HDMI IN and ARC capabilities are present in this desktop Amp/DAC. 

The K19 supports decoding from the HDMI 2.0 input and HDMI output with HDMI ARC audio return functionality, opening the doors to new ways to experience fully immersive audiovisual content.

• HDMI OUT: Supports sample rates up to 192kHz/24-bit
• HDMI ARC: Supports 44.1/48kHz sample rates

The K19 circuitry is located on separate boards for total isolation and greatly reduced interference.

We found metal protectors for the DSP board, the DAC board and the THX headphone amplifier board. All measures help minimize crosstalk to ensure complete signal purity. In addition, the aluminum alloy body with honeycomb mesh also helps to further reduce external interference, allowing you to enjoy music in the purest and cleanest way.

The dissipation systems present in the FiiO K19 allow the device to produce high power constantly without you having to worry about the problems that overheating may cause.

Its double system, on a honeycomb mesh, allows the amplifier to be completely cooled.

This FiiO K19 offers us six modes of operation and operation:

• USB decoding
• Optical input
• HDMI input
• QCC5125 Bluetooth connection with aptX HD, aptX Adaptive and LDAC
• Coaxial input
• HDMI ARC

In addition, it has multiple connection options:

• PO + PRE OUT
• PO
• PRE OUT
• LO
• COAXIAL
• OPTICS

One of the keys to the K19 is itsboth vertical and horizontal adjustment. This allows you to save space and effectively dissipate heat; When used vertically, it can also be used as a dedicated headphone stand for added convenience.

Its 1.3" color screen offers us detailed information at all times on the status of the device and makes it easy to change settings between the amplifier/DAC functions.

To make its use easier, the K19includes a remote controlthrough which you can manage all the available functionalities such as changing the operating mode, selecting an EQ or adjusting the volume. 

With 12V bidirectional trigger, the new DAC/Amp allows adaptation to other devices.
