FiiO K11 R2R – A Game-Changing DAC That Delivers $2000 Sound for a Fraction of the Price
Looking for a DAC that will completely transform your listening experience—whether on your PC, TV, or at the office with your favorite headphones? The FiiO K11 R2R DAC and Headphone Amplifier is here to change everything.
FiiO K11 R2R DAC and Headphone Amplifier for Home Audio or PC, 6.35mm and Balanced 4.4mm, RCA, Coaxial, Optical, 1300mW, 384kHz/24Bit DSD256(Black)
This is FiiO’s very first entry-level R2R DAC, and it’s already being hailed as a product that outperforms many devices costing over $2000. If you’re tired of thin, lifeless sound, this DAC will put a smile on your face and send chills down your spine.
Why the FiiO K11 R2R Stands Out
- True R2R Architecture – Built with a 24-bit fully differential resistor ladder, delivering incredibly natural, smooth sound.
- NOS and OS Modes – Choose between the pure authenticity of NOS (Non-OverSampling) or the crystal-clear detail of OS (OverSampling up to 384kHz).
- Powerful Output – 1300mW – Easily drives even demanding headphones, from audiophile dynamics to planar magnetics.
- Comprehensive Connectivity – RCA, Coaxial, Optical, 6.35mm, and Balanced 4.4mm outputs make it versatile for any setup.
- Elegant, Compact Design – Aluminum alloy body that enhances any desk or audio corner with style and minimalism.
R2R vs Traditional DAC – Why It’s a Big Deal
Most modern DACs use delta-sigma chips. While technically impressive, they often deliver a sound that’s clinically clean but lacking warmth and soul.
R2R (Resistor-to-Resistor DAC) works differently. Instead of digital modulation, it uses a precision resistor ladder to reconstruct the analog signal. The result?
- A wider, more realistic soundstage – as if the musicians are playing right in your room.
- Organic warmth and emotional impact – vocals and instruments sound alive, with true body and presence.
- Lower digital noise and distortion – giving you a blacker background and more detail.
With the K11 R2R, you finally get access to the unique charm of R2R without breaking the bank. It’s a DAC that rivals—and in many cases outshines—gear costing several thousand dollars.
The Listening Experience
In NOS Mode, the K11 R2R preserves the original sampling rate for a pure, unfiltered, analog-like sound—perfect for acoustic and vocal recordings.
In OS Mode, the audio is upsampled to 384kHz, offering sharper detail, breathtaking clarity, and pinpoint instrument separation.
This flexibility ensures that you can always tailor the sound to your mood and music style.
Frequently Asked Questions (FAQ)
1. What is an R2R DAC and how is it different from regular DACs?
An R2R DAC uses a resistor ladder to convert digital signals into analog. Unlike delta-sigma DACs, which rely heavily on digital processing, R2R DACs deliver a more natural, warm, and emotionally engaging sound.
2. Can the FiiO K11 R2R drive high-end headphones?
Absolutely. With up to 1300mW of power, it can easily drive even the most demanding audiophile headphones, including planar magnetics.

You can connect a PC, TV, smartphone, tablet, or HiFi player—essentially any device with digital or USB output.
4. Does NOS Mode really make a difference?
Yes. In NOS Mode, the DAC avoids oversampling, keeping the music in its original sampling rate for a more authentic, analog-like experience.
5. Is the K11 R2R suitable for office use?
Definitely. Its compact, sleek aluminum body not only looks stylish on your desk but also enhances your daily listening sessions with world-class sound.
