FiiO K13 R2R DAC & Headphone Amplifier – 24-Bit R2R, 2400mW, LDAC BT, Dual Power, 10-Band PEQ, XLR/RCA

Discover the FiiO K13: Desktop DAC and Headphone Amplifier

The FiiO K13 centers a self-developed 24-Bit R2R DAC built as a four-channel, fully differential circuit. Crafted with 192 ultra-precise 0.1% thin-film resistors and a low drift around 30ppm, it yields an analog-like timbre with a sense of musicality across genres.

Flexible listening with NOS and OS modes

Choose between NOS for a faithful, unaltered signal, or OS to upsample up to 384kHz. The OS path can reveal finer details and perceived clarity, while preserving the core content’s character.

• NOS preserves the original sampling rate for a purer sound
• OS upsampling to 384kHz/32-bit enhances resolution and perceived detail

Versatile connectivity for diverse setups

The K13 offers multiple outputs to fit a range of listening systems: an XLR balanced line out for clean amplification; dual RCA outputs for flexible wiring; a 4.4mm balanced headphone jack; and a 6.35mm single-ended headphone jack for standard headphones.

• XLR balanced line out
• Dual RCA outputs
• 4.4mm balanced headphone output
• 6.35mm single-ended headphone output

Support for PCM up to 384kHz/32-bit and DSD256 ensures wide compatibility with high-resolution files and streaming sources.

10-Band PEQ with Auto EQ

Navigate a self-developed 10-band parametric EQ via app or web interface. Save presets, simulate headphone response, and share EQ profiles to tailor sound to your headphones or room.

• 10-band EQ with auto EQ
• App and web control for easy adjustments
• Presets and shareable EQ profiles

Wireless high-fidelity with LDAC

Bluetooth 5.4 delivers LDAC alongside AAC and SBC, enabling high-resolution wireless streaming for setups where cables aren’t ideal.

Power, performance, and real-world use

A dual power supply design helps maintain stable operation, while the K13 can drive demanding headphones with robust headroom and controlled dynamics. The result is a responsive listening experience with a satisfying sense of scale.

In practical terms

Pair the K13 with high-impedance headphones to explore micro-detail and tonal balance, or use it as a preamp for powered speakers. Its combination of a high-quality DAC, flexible outputs, and EQ makes it a versatile desktop audio hub for varied tastes.
