FiiO KA13 Portable Headphone Amplifier 3.5mm/4.4mm sliver

Condition: New

High-resolution playback anytime, anywhere with your smartphone or tablet

The KA13 was developed as a simple, high-quality solution for high-resolution data and streaming playback, which is difficult to achieve with smartphones or Bluetooth products.

While it is bus-powered, it supports resolutions up to PCM384kHz/32bit and DSD256, and is equipped with a 3.5mm stereo headphone output as well as a 4.4mm balanced headphone output. It has a desktop mode and can output up to 550mW.

All you need is the KA13, your smartphone, and earphones/headphones to enjoy the ultimate music experience.

Dual mono DAC chip "CS43131" and op amp "SGM8262" for high-quality performance

Equipped with two high-performance, highly efficient DACs CS43131 and two low-noise op amps SGM8262. By adopting an independent DAC and amplifier configuration for each L/R channel, we have achieved excellent balanced output performance. The KA13 delivers a new experience with high-definition sound for your favorite music.

Desktop mode delivers 550mW of power, the highest in its class

A new desktop mode delivers 550mW of power, the highest in its class, for stick-type DAC amplifiers, and can powerfully drive high-impedance headphones for desktop use. The highest output power for a stick-type DAC/headphone amplifier allows you to express sound dynamically and delicately.

4.4mm balanced headphone/3.5mm unbalanced output

In addition to the 3.5mm single-ended headphone output, the KA13 also has a 4.4mm balanced headphone output, which is used in modern high-performance headphones/earphones. The newly installed desktop mode delivers a maximum output of 550mW @ 32Ω for balanced headphone output.

The KA13 has been repeatedly tuned for both output terminals, and we have finally succeeded in fitting the optimal design for the two outputs into this compact housing.

A detachable connection cable allows you to connect to a variety of devices. Adding volume adjustment improves usability
One of the features of the KA13 is that the connection cable can be removed and replaced. By switching with the included Type C or Lightning cable, it can be used with various devices. This allows you to use it according to your own device without having to buy unnecessary cables.
In addition, there is a button on the side that allows independent volume adjustment that is not linked to the connected device. You can select tracks by pressing and holding the button, which has improved usability. It provides the ultimate music experience in various scenes, such as when commuting to work or school, listening at home, and using it for gaming sound.

Performance with RGB LED illumination
The illumination with RGB LED lights not only achieves excellent design, but also helps you quickly grasp the sampling frequency of the sound source at a glance.
・Blue = 44.1-48kHz
・Yellow = 88.1-768kHz
・Green = DSD

Detailed settings are possible with the Android version of the FIIO Control app
The device settings function of the Android version of the FIIO Control app allows you to select filters, switch gain between high and low, adjust channel balance, and more. In addition, you can set the S/PDIF output ON/OFF and the RGB LED light illumination ON/OFF.
