WiiM Amp Review: The Compact Streaming Amplifier That Can Transform Your Hi-Fi Setup

A great Hi-Fi system does not necessarily need a rack full of equipment. The WiiM Amp takes the traditional concept of an integrated amplifier and brings it firmly into the streaming era, combining amplification, network streaming, multiroom functionality and extensive connectivity in one compact unit. For anyone building a new Hi-Fi system, or looking to modernise an existing pair of passive speakers, the WiiM Amp offers an unusually complete solution. It can power bookshelf speakers, floor-standing speakers and other passive speakers while giving them access to today’s most popular streaming platforms and smart-home technologies.

What Is the WiiM Amp?

At its core, the WiiM Amp is a compact Class-D integrated amplifier designed to power passive speakers while providing built-in network streaming. It delivers 60 watts per channel at 8 ohms and up to 120 watts per channel at 4 ohms, giving it enough output to work with a wide variety of Hi-Fi speakers.

The real appeal, however, is everything built around that amplifier. Instead of needing a separate amplifier, network streamer and several pieces of source equipment, the WiiM Amp brings many of those functions together in a single chassis. Its aluminium enclosure is also remarkably compact, measuring approximately 217 × 190 × 64mm, making it easy to incorporate into a TV cabinet, entertainment unit, bookshelf or dedicated Hi-Fi rack.

A Simple Way to Build a Modern Hi-Fi System

One of the biggest benefits of the WiiM Amp is how much equipment it can replace. A traditional Hi-Fi system might require an integrated amplifier, a network streamer and additional source components. The WiiM Amp effectively combines amplification and streaming into one device, reducing both the physical footprint and the complexity of the system.

Connect a pair of passive speakers, connect the WiiM Amp to your network and the core of your Hi-Fi system is ready to go. That makes it particularly appealing for listeners who want genuine stereo sound without turning their living room into an equipment showroom.

Excellent Connectivity for a Hi-Fi Setup

The WiiM Amp is designed to accommodate much more than streaming music. It features HDMI ARC, optical and line inputs, allowing it to connect to a television, CD player or other audio source. There is also a subwoofer output, making it possible to expand a stereo setup with additional low-frequency performance.

For a living-room system, HDMI ARC is particularly useful. The television can become another source for the Hi-Fi system, allowing the same speakers to handle music, television and gaming audio. There is also Bluetooth, Wi-Fi and Ethernet connectivity, giving listeners multiple ways to get audio into the system.

What about a turntable?

The WiiM Amp can also form part of a vinyl-based Hi-Fi system, although there is an important consideration: it does not have a built-in phono preamp. A turntable therefore needs either its own built-in phono stage or an external phono preamp before being connected to the WiiM Amp.

That is not necessarily a disadvantage, particularly for enthusiasts who already have a preferred phono stage, but it is worth considering when planning the system.

Streaming Is Where the WiiM Amp Really Shines

For a modern Hi-Fi setup, physical connectivity is only half the story. The WiiM Amp’s streaming capabilities are arguably one of its biggest advantages. It supports services and protocols including Spotify Connect, TIDAL Connect, AirPlay 2, Google Cast, Alexa Cast, DLNA and Roon Ready, giving users plenty of options for accessing their music.

The WiiM Home app also brings supported services and system controls together in one place. This makes the Amp particularly attractive for people who primarily listen to digital music. Instead of connecting a phone to an amplifier every time music is played, services such as Spotify Connect and TIDAL Connect can communicate directly with the WiiM Amp. The result is a much more seamless listening experience.

High-Resolution Audio Support

The WiiM Amp isn’t simply designed for convenience. It also supports high-resolution audio playback up to 24-bit/192kHz, including lossless formats such as FLAC and ALAC. Its ESS 9018 K2M DAC and published audio specifications also demonstrate that the unit has been designed with serious listening in mind. WiiM lists an analogue output signal-to-noise ratio of 98dB and THD+N of approximately 0.0025%.

In practical terms, this means the WiiM Amp is not simply a convenient wireless speaker solution. It is intended to sit within a proper stereo Hi-Fi system.

Room Correction and EQ Give You More Control

Another significant advantage is the amount of control available through the WiiM software. The Amp includes graphic and parametric EQ options, as well as room correction functionality. This matters because even an excellent pair of speakers can sound very different depending on the room they’re placed in.

Walls, furniture, speaker positioning and room dimensions can all influence the final sound. Being able to adjust the system digitally gives users more flexibility to tailor their setup rather than simply accepting the acoustic characteristics of the room. For enthusiasts who like experimenting with their sound, there is plenty to explore. For less technical listeners, the presets and room correction options provide a simpler starting point.

A Strong Match for Bookshelf and Floor-Standing Speakers

The WiiM Amp makes particular sense when paired with passive bookshelf speakers. A compact pair of quality bookshelf speakers combined with the WiiM Amp can create a clean, relatively minimalist stereo system without sacrificing access to modern streaming.

It can also be used with larger floor-standing speakers, provided the speaker’s requirements are appropriate for the amplifier. With up to 120 watts per channel at 4 ohms, the Amp has considerably more capability than its compact dimensions initially suggest. This makes it a flexible foundation for a Hi-Fi system that can potentially evolve over time.

Multiroom Audio Without Rebuilding the System

The WiiM Amp can also become part of a wider multiroom setup. Compatible WiiM devices can be grouped together, allowing music to be played throughout different rooms. The Amp can also work with compatible AirPlay 2, Google and Amazon ecosystems.

This gives the WiiM Amp an advantage over a traditional standalone amplifier. It can begin as the centre of a single-room stereo system and later become one component of a whole-home audio setup. You do not have to build the entire system at once.

A Great All-Rounder for the Living Room

Perhaps the strongest argument for the WiiM Amp is its versatility. One moment it can be powering a pair of passive speakers for Spotify. The next, those same speakers can be handling television audio through HDMI ARC. Add a subwoofer and the system gains considerably more low-end impact. Add additional WiiM products and it can become part of a multiroom system.

That versatility makes it particularly well suited to modern living rooms where one audio system is expected to handle music, television and entertainment.

The Downsides

The WiiM Amp is impressively comprehensive, but it isn’t designed to replace every type of Hi-Fi equipment. The most obvious limitation for vinyl enthusiasts is the lack of a built-in phono input. A turntable with a built-in phono preamp or an external phono stage is required.

There is also no need to expect the WiiM Amp to behave like a high-powered traditional amplifier. While its 60W per channel at 8 ohms and 120W at 4 ohms is substantial for its size, people running particularly demanding speakers or wanting very high listening levels may still prefer a more powerful dedicated amplifier.

It is also worth remembering that the standard WiiM Amp is fundamentally a stereo amplifier. It is not intended to replace a full multi-channel AV receiver for a conventional surround-sound home theatre. For a two-channel Hi-Fi setup, however, that focus is arguably part of its appeal.

Verdict: A Smart Foundation for a Modern Hi-Fi System

The WiiM Amp succeeds because it understands what modern Hi-Fi listening actually looks like.

It provides the amplification required to drive passive speakers while adding high-resolution network streaming, extensive connectivity, multiroom functionality, room correction and app-based control. It can sit comfortably at the centre of a minimalist stereo system or become the foundation for a more extensive whole-home audio setup.

For someone building a Hi-Fi system from scratch, it removes a lot of the traditional complexity. For someone who already owns passive speakers, it offers a straightforward way to bring those speakers into the modern streaming ecosystem.

Its compact size is perhaps the most misleading thing about it. The WiiM Amp occupies very little space, but it can act as the central hub for a surprisingly capable Hi-Fi system.

For listeners who want the sound and flexibility of a proper stereo setup without the clutter of multiple components, the WiiM Amp is one of the more compelling ways to bring passive speakers into the modern era.
