Flagship components, perfect sound quality

• Under the hood, the Amp Ultra uses top-of-the-line components
• ESS ES9039Q2M SABRE DAC
• Two TI TPA3255 Class-D amplifiers
• Six TI OPA1612 operational amplifiers
• Combined with Post Filter Feedback (PFFB) technology, it delivers clean and detailed sound consistently at all speaker loads – perfect for bookshelf speakers, floorstanding models or in-wall speakers.

Sound quality & power

• Delivers best-in-class 100W per channel (8Ω) and 200W (4Ω) of power with dual TI TPA3255 Class-D amplifiers
• High-quality ESS ES9039Q2M Sabre DAC + six TPA1612 op-amps ensure sound with extremely low distortion (<–105 dB THD+N) and high signal-to-noise ratio (120 dB)

Post Filter Feedback (PFFB) ensures that the sound remains clean and stable regardless of the load

At the heart of the WiiM Amp Ultra’s superior sound is its advanced Post Filter Feedback (PFFB) technology – a state-of-the-art system that reduces distortion, improves clarity and ensures consistent sound quality across a range of speaker loads. Unlike traditional amplifiers that suffer from load dependency, PFFB dynamically compensates for these variations, delivering a more accurate, balanced and natural soundscape. The result is a wider soundstage, richer detail and an immersive listening experience.
