FiiO Upgrades Its Top DAC: More Power and Luxury in the K13 R2R

Experience the rich, precise sound and boosted power of FiiO’s latest K13 R2R DAC and headphone amplifier, designed for audiophiles craving quality.

A New Benchmark in Desktop DACs

If you’re like me, always hunting for that perfect audio setup, the news of FiiO’s latest desktop DAC and headphone amplifier, the FiiO K13 R2R DAC, is nothing short of exciting. This new model takes the revered resistor ladder approach to deliver lower distortion and astonishing accuracy. It’s like FiiO took everything great from their beloved K11 R2R DAC and gave it a serious power and connectivity boost.

FiiO’s K13 R2R uses a 24-bit resistor array — the same precision tech that earned the K11 R2R its cult following. But this time, they’ve amped it up with higher output power and more versatile connection options, clocking a price tag of £279 / $319 — a steal for what it offers.

Inside the K13 R2R: Precision Meets Power

What really sets the K13 R2R apart is its resistor ladder design. This DAC features 48 precision thin-film resistors per channel, adding up to a grand total of 192 resistors across its four channels. This intricate setup means the K13 R2R produces an exceptionally rich, musical sound with very low noise and fewer unwanted harmonics.

It’s a bit like having a tiny orchestra inside your DAC, meticulously tuned to give you clarity and warmth all at once. This isn’t just about crunching numbers; it’s about creating a genuinely immersive listening experience that pulls you closer to the music.

FiiO K13 R2R: Features That Matter

Ready for the specs? The K13 R2R supports PCM decoding up to 384 kHz/32-bit and DSD256, which should satisfy even the most demanding audiophiles. Plus, it supports Bluetooth LDAC for high-res wireless streaming and includes a built-in parametric equalizer to tailor the sound exactly to your taste.

Connectivity is rich with balanced XLR outputs and not one but two RCA output sets. The power output has been seriously boosted compared to its predecessor, delivering up to 2400 mW per channel at 32 ohms. Adjustable gain means it can handle everything from powerful headphones to sensitive in-ear monitors (IEMs). The clean, low-noise power supply ensures you get pure sound without interference.

Physically, it’s slightly larger than the previous model but still compact enough for any desktop setup. A cool touch is the transparent “window” on top, giving you a peek inside the electronics — a subtle nod to audiophiles who love to see the tech at work.

The front panel houses two headphone outputs on either side of a burn-in resistant LCD display, flanked by two rotary controls for volume and input selection. For those who want remote convenience, FiiO offers app control and a bundled remote.

Availability and Pricing

FiiO is rolling out the K13 R2R this September 2025 at the recommended price of £279 / $319 (approximately $320 USD). Given its specs and build quality, this DAC/amp combo promises to be a solid contender in its price range, perfect for anyone looking to elevate their wired headphone experience.

Why the K13 R2R Should Be on Your Radar

If you’ve ever owned or wished for the original K11 R2R DAC, you’ll appreciate how the K13 R2R takes that legacy and raises it to a new level. The increased power output means those hard-to-drive headphones will finally sing, while the expanded connectivity options make it versatile for any rig.

The inclusion of Bluetooth LDAC is a clever addition, bridging the gap between wired audiophile quality and wireless convenience — which is a rare find at this price bracket.

Plus, having a parametric equalizer built-in is a neat feature that gives you granular control over your sound without needing extra gear.
