FiiO K13 R2R DAC and Headphone Amplifier

[ PRODUCT DESCRIPTION ]

 

Experience true analogue-like sound with the FiiO K13 R2R desktop DAC & headphone amplifier — designed for audiophiles who want musical warmth, detail, and power in one elegant unit.

Built with a fully differential 24-bit R2R resistor ladder DAC architecture, the K13 R2R delivers a rich, natural, and smooth sound signature that stands out from typical delta-sigma DACs. Switch between NOS (Non-Oversampling) mode for a more organic, vintage-style presentation, or Oversampling (OS) mode for cleaner and more precise detail retrieval — the choice is yours.

With high output power (up to 2400mW per channel @ 32Ω balanced), it easily drives demanding headphones while maintaining excellent control and dynamics. Whether you use IEMs or full-size headphones, the K13 R2R provides clean, powerful amplification with low noise performance.

Equipped with USB, optical, and coaxial inputs, plus balanced and single-ended outputs, it fits perfectly into any desktop HiFi setup. You can also fine-tune your sound with built-in PEQ adjustments via the FiiO Control app.

Finished with a premium aluminium chassis, HD display, and customizable RGB lighting, the K13 R2R not only sounds amazing — it looks stunning on your desk too.

Upgrade your listening experience today with the FiiO K13 R2R — where analogue soul meets modern performance.
