WiiM Amp Ultra

• 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.

• 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.

• 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.
