Experience Unparalleled Audio with the FiiO K11 R2R Desktop DAC/AMP

Discover the pinnacle of audio excellence with FiiO's latest release, the K11 R2R Desktop DAC/AMP. Building on the success of its predecessors, the K11 R2R introduces a self-developed, fully differential 24-Bit R2R Resistor Array that promises a smooth, rich, and organic sound experience. Whether you're an audiophile or a casual listener, the K11 R2R's innovative features ensure a superior listening journey.

State-of-the-Art 24-Bit R2R DAC Array

The K11 R2R is equipped with FiiO's cutting-edge four-channel fully differential 24-bit R2R resistor array. With 48 resistors per channel and a total of 192 ultra-precise resistors (0.1% accuracy and low-temperature drift), this array ensures a pristine output and a dark, noise-free background. This advanced circuit design delivers exceptional audio clarity and detail.

Versatile NOS/OS Dual Operating Modes

The K11 R2R offers dual operating modes: NOS (Non-Oversampling) and OS (Oversampling). Switch between these modes to enjoy different sound characteristics. The NOS mode retains the original sampling rate, providing a more musical and natural sound. In contrast, the OS mode upscales signals to 384kHz, offering enhanced detail and clarity. Tailor your listening experience to your preference with ease.

High-Powered Amp Section for Superior Output

Designed for audiophiles, the K11 R2R's powerful amp section includes TI OPA1642 low-pass filters and dual SGM8262 professional-grade operational amplifiers. With an impressive output power of up to 1300mW per channel, it can effortlessly drive even the most demanding headphones. The three-level gain adjustment ensures compatibility with both sensitive IEMs and power-hungry headphones, while the NJW1195A precise digital volume chipset allows for fine-tuned volume control with minimal distortion.

Dual Headphone Outputs for Maximum Flexibility

Featuring both a 6.35mm single-ended and a 4.4mm balanced headphone output, the K11 R2R offers versatile connectivity options. Whether you prefer single-ended or balanced connections, you can easily pair a variety of IEMs and headphones to enjoy high-resolution audio in its purest form.

High-Resolution Audio Support

The K11 R2R excels in high-resolution audio processing, supporting PCM and DSD signals up to 32-bit/384kHz PCM and DSD256. With native DSD output mode, your audio is processed internally to PCM for an authentic R2R experience. Enjoy every nuance of your music with true high-resolution signal decoding.

Professionally Engineered Low-Noise Power Supply

To ensure the highest sound quality, the K11 R2R incorporates a low-noise power supply system. It features 17 low-noise LDO precision voltage regulators and 2 DC-DC converters, providing a stable and clean power supply. The external 12V power supply further minimizes noise and distortion, ensuring a flawless audio output.

Elevate Your Listening Experience with the FiiO K11 R2R

With its advanced R2R resistor array, versatile operating modes, powerful amplification, and meticulous design, the FiiO K11 R2R is the ultimate desktop DAC/AMP for discerning audiophiles. Immerse yourself in rich, smooth, and organic sound like never before.
