FiiO K7 - Standard

Description

A New Standard in Balanced Desktop Sound
The FiiO K7 sets a new benchmark for desktop DAC/amp performance by combining truly balanced architecture, dual flagship-level DACs, and THX AAA 788+ amplification in a compact but powerful package. With cutting-edge decoding, versatile I/O, and intelligent protection systems, the K7 delivers premium sound with elegance, precision, and confidence—whether for casual listening or professional-grade setups.

Dual AK4493SEQ Flagship DACs
At the core of the K7, two AK4493SEQ DACs handle left and right channels independently, ensuring a true balanced architecture and rich, delicate sonic performance. Known for their refined timbre and musicality, these DACs reproduce detail and nuance that allow you to rediscover your music with clarity and emotion.

Powerful THX AAA 788+ Amplification
Borrowing from the flagship K9 Pro, the K7 integrates dual THX AAA 788+ modules for exceptionally clean and powerful amplification. The K7 delivers up to 560 mW into 300Ω and a remarkable 2000 mW into 32Ω with less than 1% distortion—capable of easily driving both demanding high-impedance headphones and sensitive in-ears with equal control.

Six-Stage Balanced Audio Circuit
The balanced six-stage circuit design isolates digital and analog sections, significantly reducing crosstalk to preserve purity and spaciousness. This ensures the K7 reproduces music as the artist intended, with low noise and consistent tonality across all outputs.

Robust Decoding with XMOS Processor
Equipped with an XMOS XUF208 USB interface and dual clock management, the K7 supports high-resolution formats with effortless precision—from PCM to DSD—giving users access to a wide universe of music sources.

Refined Power Design and External Supply
Clean, stable power is supplied through a 12V/24W low-noise external adapter, feeding into a finely engineered multi-stage regulation system with numerous independent low-noise LDOs. This topology ensures each part of the audio chain receives optimal supply, supporting consistent, distortion-free audio at any level.

Three Output Modes and Gain Control
By simply pressing a switch, the K7 adapts seamlessly to multifunctional use as a headphone amp, preamplifier for speakers, or standalone DAC. Users can also toggle between high and low hardware gain, allowing smooth pairing with a variety of headphones, from ultra-sensitive IEMs to difficult high-impedance models.

Precision Volume with RGB Indicators
Thanks to ADC curve reconstruction, the K7 offers precise, noise-free 112-step volume adjustment without channel imbalance, ensuring smooth operation and flawless reproduction of every note. Its RGB status indicators provide a colorful light flow effect on startup, input switching, and playback, adding personality and convenience to its user experience.

Premium Build and Compact Footprint
The K7 is crafted from aluminum alloy with precision CNC machining, finished with black anodization and accented by detailed Hi-Res and THX badges. Measuring just 55 mm in height with a footprint under one-third of A4 size, it integrates easily into modern desktops while providing striking style.
