WiiM Amp Pro space gray

The WiiM Amp Pro space grey is a stereo integrated hi-fi amplifier that offers power, sound quality, and streaming features in a compact and elegant design. Designed for music enthusiasts seeking simplicity, this device transforms your passive speakers into a smart and high-performance audio system.

Sound Quality

At the heart of the WiiM Amp Pro is a carefully designed audio chain that delivers faithful and detailed sound reproduction. The ESS SABRE ES9038Q2M DAC, renowned for its audiophile performance, supports high-resolution audio playback up to 24-bit/192 kHz. This digital precision translates into exceptional clarity and faithful reproduction of musical nuances.

The TI TPA3255 Class D amplifier ensures efficient amplification with low distortion. With a signal-to-noise ratio (SNR) of 120 dB and a total harmonic distortion plus noise (THD+N) of -105 dB at 5 W, the WiiM Amp Pro delivers pure and transparent sound, even at high volumes.

To further optimize sound performance, the amplifier includes a room acoustic correction feature. This technology analyzes the listening environment and automatically adjusts the frequency response to compensate for unwanted resonances and reflections, ensuring an optimal listening experience in any space.

Versatile Connectivity and Limitless Streaming

The WiiM Amp Pro stands out for its versatility in connectivity. On the wireless side, it supports tri-band Wi-Fi 6E (2.4 GHz, 5 GHz, and 6 GHz) for stable and fast streaming, as well as Bluetooth 5.3 with LE Audio codec support for high-quality wireless connections.

For physical sources, the amplifier offers a full range of inputs: HDMI ARC for easy integration with modern TVs, optical input for digital sources, analog line input for traditional sources, and even a USB-A port for direct playback from USB drives or external hard drives.

In terms of streaming, the WiiM Amp Pro supports a multitude of services and protocols. Chromecast, Spotify Connect, TIDAL Connect, and Alexa Cast are natively integrated, allowing direct streaming from their respective apps. The device is also DLNA-compatible for streaming from local media servers and Roon-ready, offering maximum flexibility for demanding audiophiles.

A Smart Musical Brain

The WiiM Home app transforms your smartphone into a smart remote control for the WiiM Amp Pro. It not only allows you to control playback and volume but also provides access to a multitude of streaming services directly from the interface. Spotify, Amazon Music, Deezer, TuneIn, Tidal, Qobuz, and many more are just a few taps away.

The amplifier goes beyond simple remote control by offering voice assistant features. Compatible with Alexa, Google Assistant, and Siri, it enables hands-free control of your music and audio settings. The included voice remote adds an extra layer of convenience for those who prefer physical controls.

For audiophiles who enjoy fine-tuning their sound, the WiiM Amp Pro offers advanced equalization options. A 10-band graphic equalizer, a 10-band parametric equalizer, and 26 equalizer presets provide precise control over the amplifier’s sound signature.

Versatility and Scalability

The WiiM Amp Pro adapts to a variety of audio configurations. It is compatible with speakers of various impedances (8 ohms, 6 ohms, 4 ohms) and can even handle two pairs of 8-ohm speakers in parallel. The dedicated subwoofer output, with automatic detection and adjustable filter, extends the bass response for deep sound enthusiasts.

In a multiroom context, the amplifier integrates seamlessly with other WiiM devices, Amazon Echo speakers, or Google Home devices. This flexibility allows you to create a cohesive audio system throughout your home, controllable from a single interface.

For movie enthusiasts, Dolby Digital support via the HDMI ARC input allows the WiiM Amp Pro to serve as the central hub of a compact yet powerful home theater system.

WiiM Amp Pro vs. WiiM Amp: What Are the Main Differences?

In terms of audio, it features a more advanced ESS ES9038Q2M DAC, offering a signal-to-noise ratio of 120 dB (compared to 98 dB) and reduced total harmonic distortion to 0.0005% (-105 dB). The Post Filter Feedback (PFFB) technology enhances sound clarity and precision. On the connectivity side, the Pro upgrades to Wi-Fi 6E and Bluetooth 5.3 with LE Audio support. It adds advanced features like automatic room correction and a 10-band parametric EQ in addition to the graphic EQ, with 24 presets instead of 12. The power remains the same (2x100W at 4 ohms) but with better handling of reactive loads. The design evolves to an aluminum casing for improved heat dissipation.
