WiiM Amp Ultra Streaming Amplifier

About The WiiM Amp Ultra Streaming Amplifier

The WiiM Amp Ultra is a sleek, powerhouse streaming amplifier built for serious listening and modern lifestyles. With class-leading Class‑D amplification, a high‑end DAC, touchscreen control, room calibration, cinematic HDMI ARC functionality, and rich smart integration - it checks just about every box. Whether you're chasing silent background ambiance or full-on movie immersion, it's a beautifully crafted, future-ready all-in-one that truly delivers.

Built for music lovers, home theatre buffs, and smart home fans, it delivers a stunning 100W per channel @ 8Ω with ultra-low distortion, pushing high-fidelity audio to every corner of your listening space. Designed to stand out but also fit in, the Amp Ultra features a sleek unibody aluminium chassis and a vibrant 3.5" glass-covered colour touchscreen. Easily control playback, switch sources, view album art, and more - all at your fingertips.

Flagship Components, Flawless Fidelity: Under the hood, the Amp Ultra is powered by top-tier components including the ESS ES9039 Q2M Sabre DAC, dual TI TPA3255 Class-D Amplifiers and six TI OPA1612 Op-Amps

Combined with Post Filter Feedback (PFFB) technology, it delivers clean, detailed sound with consistent performance across all speaker loads - perfect for bookshelf, floorstanding, or in-wall/in-ceiling speakers.

Post Filter Feedback Technology: At the core of the WiiM Amp Ultra's superior sound is its advanced Post-Filter Feedback (PFFB) technology, a cutting-edge refinement system that minimises distortion, enhances clarity, and ensures consistent sound quality across different speaker loads. Unlike traditional amplifiers that suffer from load-dependent performance variations, PFFB dynamically compensates for these inconsistencies, delivering a more accurate, balanced, and natural sound signature. The result is a wider soundstage, richer details, and an immersive listening experience that faithfully reproduces every note with precision and depth.

Advanced Thermal Management: High-power amplification generates heat, but the WiiM Amp Ultra stays cool under pressure with advanced thermal management:

• Copper Heat Pipe – Rapidly transfers heat from key components for stable performance at any volume.
• Large Aluminium Heatsink – Exceptional conductivity ensures fast, efficient cooling, preventing thermal throttling.
• Precision PID Control – Real-time temperature regulation for optimal cooling and long-term reliability.

Next-Gen Wireless Streaming: Stay connected with the latest in wireless tech including Wi-Fi 6 (Tri-Band) and Bluetooth 5.3 with SBC and AAC support. Stream ultra-high-resolution audio with near-zero latency - no dropouts, no lag, just music.

See Your Sound: A vivid 3.5″ glass touchscreen puts album art, VU meters, and one-tap controls front and centre - making input switching, setting tweaks, and playback navigation effortless, with instant visual feedback.

Built-In RoomFit™ Room Correction: Every room is different - WiiM Amp Ultra adapts. Using built-in acoustic measurement and correction, it tunes your setup to match your environment, optimizing for speaker type, distance, and room acoustics.

All the Music You Love, All in One Place: Stream directly from your favourite platforms: Spotify, Amazon Music, TIDAL, Qobuz, Deezer, TuneIn, SoundCloud, and more. Prefer using your own apps? No problem - Amp Ultra supports: Chromecast, Alexa Cast, Spotify Connect, TIDAL Connect, Qobuz Connect, DLNA, SqueezeLite, and Roon (pending certification).

Tailor Your Sound: Dial in the perfect tone with a plethora of equalization options. You have 24 Preset EQ Profiles, a 10-Band Graphic and Parametric EQ, the convenience of per-input EQ settings and a Subwoofer crossover control.

Versatile Connectivity: Easily integrate turntables, TVs, CD players, or stream to any WiiM or Bluetooth-enabled device.

Control Everything with the WiiM Home App: One App, total control, just what you’ve always wanted. Stream music, adjust EQ, group rooms, set alarms, or update firmware with ease - right from your phone or tablet.

Take Full Control with the WiiM Voice Remote 2: WiiM Voice Remote 2 is crafted with a sleek aluminium body, rechargeable battery, and intuitive Push-to-Talk voice commands - plus smart presets and dedicated playback buttons for a seamless, intuitive experience.
