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
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.
