The FiiO K19 Headphone Amplifier & DAC is a pinnacle of audio engineering, featuring cutting-edge technology designed to elevate your listening experience to new heights. At its core, the K19 boasts not one, but two THX AAA-788+ modules dedicated to signal amplification. This innovative design ensures unparalleled clarity and power, with each channel capable of delivering up to an astonishing 8000mW of output power at 32 ohms.

Connectivity

What really sets the K19 apart is its range of connections. It’s got all the digital inputs you could need—USB-C, Toslink optical, and SPDIF coaxial—plus, it’s got something special: an HDMI port and an HDMI e-ARC port. That means it can hook up to all your devices seamlessly, making it super versatile.

And it’s not just about inputs—the K19 has you covered on the output side too. There’s digital outputs like Toslink optical and coaxial SPDIF, as well as analog options including stereo balanced XLR line output, stereo RCA line output, and headphone outputs in both 6.35mm and 4.4mm balanced versions. So, no matter what gear you’ve got, the K19 can handle it.

It’s got some handy extras too, like two 3.5mm Trigger IN/Trigger OUT 12V jack ports for extra control options, and an RS232 interface on a USB-C port for even more compatibility.

Next-gen Bluetooth

The K19 showcases a bi-directional Bluetooth chip (receiver/transmitter), enabling it to uphold the following wireless transmission codecs: SBC, AAC, aptX, aptX HD, and LDAC.

Two ES9039MSPRO DAC chips

The K19 incorporates two DAC chips for balanced audio channel processing. The ES9039MSPRO DAC chips are 32bit, 8-channel DAC chips specially designed for professional applications. They enable the FiiO K19 to support high-resolution PCM 32bit 768kHz and native DSD streams up to DSD512. In addition, these DAC chips are combined with two ACCUSILLON AS318-B crystal oscillators to guarantee a perfect clock signal. FIIO K19: two THX AAA-788+ amplifier modules Headphone amplification is provided by two THX AAA-788+ modules, for exceptional output power of up to 8000mW per channel. As a result, the K19 can drive any type of audiophile headphone on the market, whether with 32 or 600 ohms impedance. FIIO K19: next-generation Bluetooth The K19 features a bi-directional Bluetooth chip (receiver/transmitter), enabling it to support the following wireless transmission codecs: SBC, AAC, aptX, aptX HD and LDAC. FIIO K19: integrated DSP with 31-band EQ The K19 incorporates an ADI SHARC+ ADSP-21565 DSP from Analog Devices Inc., giving users the benefit of a 31-band parametric equalizer. As a result, the K19’s tuning control is extremely precise over a wide range of frequencies. This feature enables the user to adapt the sound to his preferences and the type of music he is listening to. FIIO K19: dual power supply A switch allows you to select the power supply mode, either 220V AC mains or 15V DC, to suit various configurations. A grounding switch, also located on the rear of the unit, resolves potential ground loop problems and effectively eliminates noise.
