The WiiM Amp Ultra Wireless Streaming Amplifier represents a significant leap forward in integrated audio technology, combining raw power with surgical precision in a compact, unibody aluminum chassis. Designed as the flagship "all-in-one" solution for the modern audiophile, the Amp Ultra is not just an amplifier but a comprehensive digital-to-analog command center. Whether you are looking to revitalize a pair of classic passive floor-standing speakers or build a high-performance home theater hub around a pair of modern bookshelves, the Amp Ultra provides the muscle and intelligence required to deliver a studio-quality listening experience. Housed in a sophisticated Space Gray aluminum shell, it features a vibrant 3.5-inch glass touchscreen that transforms the act of music discovery into a tactile, visual journey, displaying everything from high-resolution album art to real-time VU meters.
Under the hood, the WiiM Amp Ultra is powered by an audiophile-grade architecture that prioritizes transparency and low-distortion performance. It utilizes the premium 32-bit/384kHz ESS ES9039Q2M SABRE DAC, a component typically reserved for high-end standalone converters, paired with dual TI TPA3255 Class-D amplifier chips. This combination allows the unit to deliver a staggering 100 watts per channel into 8 ohms, or up to 200 watts per channel into 4 ohms. This robust power delivery is managed by innovative Post Filter Feedback (PFFB) technology, which ensures that the amplifier remains load-independent. Unlike many budget Class-D amplifiers that change their sound signature depending on the speakers connected, the Amp Ultra maintains a flat, accurate frequency response regardless of whether you are driving 4-ohm or 8-ohm loads.
One of the most transformative features of the WiiM Amp Ultra is the integrated RoomFit™ calibration technology. No matter how high-quality your speakers are, the room they are in will always color the sound, often introducing unwanted bass "boom" or harsh reflections. The Amp Ultra uses a built-in acoustic measurement system to analyze the unique properties of your listening space and automatically apply correction filters. This optimizes the soundstage, improves tonal balance, and ensures that the transition between your speakers and an external subwoofer is perfectly seamless. For those who prefer a more hands-on approach, the WiiM Home App provides a comprehensive 10-band graphic and parametric EQ, allowing you to fine-tune the audio for every specific input source, from your turntable to your television.
The Amp Ultra is designed to be the central nervous system of your home entertainment setup. Connectivity is truly "next-gen," featuring Wi-Fi 6E for rock-solid, high-bandwidth streaming and Bluetooth 5.3 for low-latency wireless transmission. For the modern living room, the inclusion of HDMI ARC (with Dolby Digital decoding) is a game-changer. By connecting a single HDMI cable to your TV, the Amp Ultra automatically takes over as your audio processor, allowing you to control the volume using your existing TV remote while delivering cinematic depth and clarity that integrated TV speakers simply cannot match. It also features a dedicated subwoofer output with adjustable crossover management, making it easy to create a powerful 2.1-channel system that handles both high-fidelity music and explosive movie soundtracks with equal competence.
Integration into the digital ecosystem is effortless. The Amp Ultra supports all major streaming protocols including Google Cast, Spotify Connect, Tidal Connect, and Alexa Cast, and is Roon Ready. This means you can stream your favorite playlists in bit-perfect 24-bit/192kHz resolution directly from the cloud using the apps you already know. The WiiM Home App further enhances this by aggregating services like Qobuz, Amazon Music, and Deezer into a single, intuitive interface. Additionally, the Amp Ultra includes a high-quality RCA Line-In for analog sources such as CD players or turntables (with an external preamp), and a USB port for local media playback. It can even function as a multi-room hub, allowing you to synchronize music across every room in your house using other WiiM devices or compatible smart speakers.
Durability and thermal efficiency were core priorities during the development of the Amp Ultra. To maintain stable performance during high-volume listening sessions, the unit features an advanced thermal management system consisting of a copper heat pipe and a large aluminum heatsink. This passive cooling design ensures the amplifier stays cool and operates silently without the need for noisy internal fans. The precision PID-controlled regulation monitors internal temperatures in real-time, protecting your investment and ensuring long-term reliability. Included with the unit is the WiiM Voice Remote 2, an aluminum-bodied rechargeable remote that offers push-to-talk voice commands and smart presets for your most-played content, ensuring that high-end audio is never more than a single click or a simple voice command away.
In summary, the WiiM Amp Ultra is a masterclass in modern audio engineering, offering an unprecedented balance of power, connectivity, and intelligent room correction. It simplifies the audiophile journey by replacing stacks of bulky equipment with a single, elegant device that excels at both two-channel music and home theater audio. By choosing the Amp Ultra, you are investing in a future-proof audio hub that will grow with your system through frequent over-the-air firmware updates, ensuring that you always have access to the latest streaming technologies and sonic enhancements. It doesn't just play music; it elevates every aspect of your acoustic environment.
