Product Information
Unlocking rich, full-bodied sound from your headphones, the FIIO K11 R2R delivers a unique listening experience.
High quality headphone amp made better
Featuring a raft of improvements, FIIO have made the K11 more appealing than ever. The FIIO K11 R2R uses a fully differential 24-bit DAC with resistor arrays for reduced distortion and enhanced musical depth. You can now also switch between NOS (Non-Oversampling) and OS (Oversampling) modes for the sound you prefer. An upgraded volume control delivers improved control. Combined with all the other features that makes the existing K11 such a standout product, the R2R truly gets the very best from your music.
FIIO’s first discrete DAC for enhanced sound
The FIIO K11 R2R is its first product to use a discrete, resistor based DAC (Digital to Analogue Convertor). Rather than using a single microchip, the DAC circuit is made up of dozens of thin-film resistors, carefully configured within the highest tolerances. This unique configuration gives the K11 R2R a more natural and organic sound that’s musical and engaging for long term listening.
Choose between Oversampled or Non-Oversampled sound
For the sound that best suits you and your music, you can switch between NOS (Non-Oversampled) and OS (Oversampled) sound. NOS maintains the music’s full originality, with an authenticity that’s true to the musician’s intentions. OS upsamples the signal to 384kHz, for an enhanced performance with improved refinement. Each setting suits different types of music and tastes.
Ultra-precise volume control
As well as using an uprated DAC, the K11 R2R also features a new, high quality electronic volume control. Using a resistor ladder, the electronic volume control offers precise adjustment and very low levels of noise.
Wide ranging headphone compatibility
With up to 1300mW power output, the K11 R2R easily drives the most power-hungry headphones, meaning that you get to hear your headphones at their best, with the full bass potential finally revealed. Low, Medium and High Gain Modes means that the amp seamlessly matches your headphones.
Balanced output for enhanced sound from compatible headphones
For the highest quality connection, there’s a choice of headphone outputs, including 4.4mm balanced as well as a regular 6.35mm output. When used with compatible headphones, the balanced 4.4mm output maximises the music’s detail by reducing the potential for distortion to the lowest levels possible. RCA phono outputs also let you connect the K11 R2R to your hi-fi system and use it as a standalone DAC.
Range of digital inputs
With a range of connections, the FIIO K11 R2R is a versatile hub for a range of devices. Connect your laptop or desktop via the USB-C connection and enjoy the very best in High-Resolution music streaming. Coaxial and optical digital inputs suit a TV, network streamer or CD player. Outputs are via analogue RCA or digital coaxial.*
*Digital coaxial operates as input OR output only.
Sleek design
The K11 R2R’s sleek design and horizontal or vertical positioning makes it desktop friendly. The high contrast display clearly shows handy information, such as sampling rate, volume, gain and output mode.
Enjoy a richer sound from your headphones, with the FIIO K11 R2R.
