This little beast of a device packs serious performance with a fully-differential true 24-bit R2R resistor array DAC setup and a powerful, fully-balanced amp section that produces a thunderous 2.4W output per channel. Equipped with an advanced XMOS USB processor, the K13 supports up to 32bit/384kHz PCM and native DSD256 audio signals. It supports USB, Coaxial, Optical, and Bluetooth connections for input. FiiO K13 adopts a specially-designed DC/AC dual power supply design, which provides clean power input with anti-interference capabilities. FiiO K13 has a clean, minimalistic design featuring an unibody aluminium alloy casing, and a brand-new “Skylight” design where FiiO has featured a circular glass window on the top. Through this glass window, the internal R2R DAC array is visible. The K13 is a special DAC/AMP with a special sound profile; its fully-differential R2R array, along with a high-power amp setup, promises a quality music listening experience for its users. Experience true high-fidelity with the FiiO K13 as your desktop companion!!
Fully-Differential True 24-Bit R2R DAC Setup:-
FiiO K13’s special sauce is its high-performance DAC setup, which is crafted using a fully-differential true 24-bit R2R resistor array arrangement. It’s FiiO’s proprietary four-channel DAC setup which includes 48 precision thin-film resistors per channel, totalling 192 resistors across the four channels. Each resistor has 0.1% accuracy and low-temperature drift. This R2R arrangement delivers a uniquely rich and musical sound profile that captivates listeners with its immersive experience.
Dual NOS/OS Modes:-
The FiiO K13 supports dual operating modes, NOS(Non-Oversampling) and OS(Oversampling). NOS mode maintains the original sampling rate of the recording and preserves its authentic sound response, while the OS mode upsamples the sound signal globally to a high sampling rate of 384kHz, which promises superior quality with a refined, clearer, and cleaner sound profile.
Your True Desktop Hub:-
FiiO K13, on its own, is a proper desktop hub that will allow you to enjoy your music to its fullest. The device can act as a DAC/AMP or as a dedicated DAC as well, with pre-amp and line-out features. It has both RCA as well as XLR pre/line-out options. Pair the K13 with your IEMs, Headphones, or use it as a dedicated pre-amp or DAC for active speakers or power amplifiers as well.
Fully Balanced Audio Amplification:-
Fiio K13 packs in a powerful headphone amp section featuring a fully-balanced headphone amplification architecture. It includes high-quality components such as dual OPA1642 and dual TPA6120A chips. The K13 boasts a maximum output of 2400mW per channel at 32Ω impedance load. The K13 can effortlessly drive both high-sensitivity IEMs and low-sensitivity headphones. For easy pairing, the K13 has three-level adjustable gain modes.
Customize Your Sound with 10-Band PEQ:-
FiiO K13 features specially developed 1-band PEQ support, which is accessible via the FiiO application or web interface. You can easily utilize the preset tuning profiles or even simulate and correct the output to your liking with the built-in 10-band PEQ. It supports exporting, importing, sharing, and saving EQ curves. Tuning adjustments on the K13 offer next-level customization with individual frequency, gain, and Q-factor adjustments.
Specially-Developed Dual-Mode Power Supply:-
FiiO K13 features a built-in 30W switching power supply. It works in both AC as well as DC modes. The power supply is protected by an alloy-nickel-plated shielding cover, which significantly boosts its anti-interference capabilities and ensures a clean power supply to all the components. The DC power input allows you to pair the K13 with a high-performance linear power supply for an even enhanced music listening experience. Featuring up to 18 low-noise LDOs and 5DC-DC converters in total, the K13 features a multi-rail power supply for a clean and strong power delivery.
