Condition: Like New. Fully tested, powers on, cycles settings, no visible damage.

Experience premium sound with the FiiO K7 Desktop DAC and Amplifier. Featuring dual AK4493SEQ DACs and dual THX AAA 788+ amplifiers, the K7 delivers accurate and immersive audio for any workspace. Designed for users who value clarity, the FiiO K7 is built for performance and ease of use.

Every detail in the K7 design serves the goal of cleaner sound. Each DAC chip processes a single channel. This separation minimizes crosstalk. The result is balanced, richer audio. High and low frequencies remain distinct and true to the source. Rediscover your music library with new detail and depth.

The K7 uses two THX AAA 788+ amplifiers, the same technology as FiiO's advanced K9 Pro. Power output reaches 560mW at 300Ω and 2000mW at 32Ω with 1% distortion. This means you get power for both easy-to-drive IEMs and harder-to-drive full-size headphones. It keeps sound consistent, whether you're using Sennheiser, Beyerdynamic, or another popular brand. Switch easily between different headphones without losing quality.

Connect the K7 to almost any setup. USB, optical, coaxial, and RCA inputs allow links to computers, phones, and audio players. For output, there is a standard 6.35mm single-ended jack and a 4.4mm balanced jack. Prefer to use speakers? The K7 offers RCA line out so you can connect to external amplifiers or active speakers. It's a flexible, central solution for at-home or office audio.

The RGB indicator lights are a highlight. These change color to show playback format, making device status clear at a glance. Blue indicates 44.1kHz/48kHz audio, yellow for higher PCM, and green for DSD. The lights also add stylish flair to your desk. You always know exactly what you are listening to.

Volume control is smooth and precise. An ADC volume control circuit offers 112 fine steps, reducing noise and channel mismatch. You can make tiny adjustments, finding your perfect listening level every time. Two hardware gain levels help you easily adapt to different headphones without jumping through menus.

Build quality stands out. The all-aluminum case is strong but lightweight, keeping the devices safe from everyday bumps or knocks. Gold ring accents and colorful lights bring a modern, premium feel. The compact size—120mm wide, 168mm deep, and only 55mm tall—means it fits on any desk or shelf without clutter.

The K7’s power supply design uses low-noise LDOs in each stage. This ensures steady, clean power for the DAC and amp. Powered by an external 12V/24W brick, interference is minimized. You get a pure, distortion-free sound even at high volumes or with sensitive headphones. Long sessions are always comfortable and safe for your equipment.

FiiO also offers a Bluetooth edition of the K7 with the QCC5124 chip. This version streams wirelessly with high-fidelity formats like LDAC, aptX HD, and aptX Adaptive. You get wireless freedom and high-quality audio at the same time. Use the FiiO Control app to adjust Bluetooth codecs, update firmware, or tune the built-in equalizer (PEQ). It’s easy to customize the K7 to your taste via your phone.

Every FiiO K7 is rigorously tested before shipment. This ensures excellent reliability and long-term performance. The device is backed by the reputation of FiiO, known for innovation and quality in desktop audio.

Upgrade from basic amplifiers and step into a new world of detail with the FiiO K7. Enjoy warm, deep bass and crisp highs. This DAC is perfect for music, movies, or games, making every session more engaging. No matter your source, the K7 adapts, always aiming for the best sound quality available.
