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.
