Unleash Studio-Quality Sound

Meet the WiiM Amp Ultra – our most advanced streaming amplifier yet. Built for music lovers, home theater buffs, and smart home fans, it delivers stunning 100W per channel (8Ω) with ultra-low distortion, pushing high-fidelity audio to every corner of your space. Whether it’s vinyl, Spotify, or cinematic surround sound—you’ll hear it like never before.


Beautiful Inside and Out

Designed to stand out and fit in, the Amp Ultra features a sleek unibody aluminum chassis and a vibrant 3.5″ glass-covered 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:
  • ESS ES9039Q2M SABRE DAC
  • Dual TI TPA3255 Class-D amplifiers
  • 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, floor-standing, or in-wall 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 minimizes 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? 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 Aluminum 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:
  • Wi-Fi 6 (Tri-Band)
  • Bluetooth 5.3 with SBC and AAC support
  • Stream ultra-high-resolution audio with near-zero latency—no dropouts, no lag, just music.
