Sound Quality
The WiiM Amp Ultra is not trying to compete with separates — and that honesty is what makes it so appealing. It uses an ESS ES9038Q2M DAC chip, the same silicon found in streamers costing three times as much, and pairs it with a Class D amplifier rated at 60W per channel.
The DAC section is genuinely impressive for the price. Through the line-out into an external amplifier, the Amp Ultra delivers a clean, detailed signal with good dynamics and a wide frequency response. It is competitive with standalone streamers like the Bluesound Node at twice the price.
Through the built-in amplifier, the sound is a step down from dedicated amps but still remarkably capable. Paired with efficient bookshelf speakers like the KEF Q150 or Klipsch RP-600M II, the Amp Ultra fills a medium room with engaging, detailed sound. Bass control is good for a Class D amp at this price, though it lacks the authority of a proper integrated.
Build & Design
The Amp Ultra is compact and lightweight at just 1.9kg. The plastic enclosure feels less premium than the Cambridge Audio or WiiM’s own Pro Plus streamer, but at $369 for an all-in-one, material compromises are expected.
Connectivity is outstanding. HDMI eARC means it doubles as a TV audio solution, Wi-Fi 6 ensures stable high-resolution streaming, and Bluetooth 5.3 covers casual listening. The WiiM Home app is the best streaming control app in the budget segment — fast, intuitive, and feature-rich with built-in room EQ, parametric EQ, and crossover settings for subwoofer integration.
Value Proposition
The WiiM Amp Ultra competes with nothing because nothing else offers this feature set at $369. The closest competitor is the Sonos Amp at $699, which offers more power but lacks the audiophile DAC, Roon Ready certification, and the flexibility of the WiiM platform.
For anyone building a first hi-fi system, a bedroom setup, or a multi-room audio zone, the Amp Ultra is the most logical starting point in 2026.
