FiiO K13 R2R – HEADPHONE AMP/DAC

The FiiO K13 R2R is a desktop 24-bit R2R DAC and headphone amplifier combo. It features a fully differential resistor array layout with 192 precision resistors, switchable NOS/OS (Non-Oversampling/Oversampling) modes, Bluetooth 5.4 with LDAC, up to 2400 mW power output at 32 ohms, and a 10-band parametric EQ

FiiO K13 R2R - Design and Features

• Build: CNC-machined aluminum "Skylight" chassis featuring a top glass window that exposes the illuminated R2R resistor ladders.
• Inputs: Dual USB-C, coaxial, optical, and wireless Bluetooth 5.4.
• Outputs: 4.4 mm balanced and 6.35 mm single-ended headphone jacks on the front; RCA and balanced XLR line-outs on the rear.
• Control: Dual rotary knobs, an infrared remote control, and companion app support for parametric EQ adjustments.

FiiO K13 R2R - Sound and Performance

• Tonal Character: Delivers an organic, wide soundstage presentation characteristic of R2R ladders. NOS mode leans toward a relaxed, analog feel, while OS mode provides a more transparent and neutral profile
• Power: Provides substantial punch via its balanced output (2400 mW into 32 Ω), easily driving most mid-to-high impedance dynamic and planar headphones.
