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.
