WIIM AMP PRO

The WiiM Amp Pro is a second-generation streaming amplifier designed for those who demand high-level audio performance. Thanks to Post Filter Feedback (PFFB) technology, it ensures superior sound quality regardless of the connected load. This feedback circuit, implemented with a secondary feedback loop, reduces output noise and improves frequency response, minimizing distortion and the influence of load impedance.

Amplification is powered by the robust TI TPA3255 Class D module, while digital-to-analog conversion is handled by the ESS ES9038Q2M DAC, delivering an ultra-low total harmonic distortion (THD+N) of -105 dB and a signal-to-noise ratio (SNR) of 120 dB at 5W. The power output delivers 60 watts per channel at 8 ohms and 120 watts per channel at 4 ohms, making it suitable for a wide range of passive speakers.

The WiiM Amp Pro stands out for its advanced connectivity, featuring Wi-Fi 6E and Bluetooth 5.3 with BT LE. The dual-antenna design ensures a stable transmission even in challenging conditions. HDMI ARC support enables seamless TV integration, enhancing audio quality with the built-in Dolby decoder and a dedicated subwoofer output. Analog inputs accommodate turntables, TVs, or traditional audio sources, while compatibility with Chromecast, Alexa Cast, DLNA, Spotify Connect, and TIDAL Connect allows direct music streaming from popular apps.

The WiiM Home app provides complete control over the amplifier and access to a broad range of streaming services, including Spotify, Qobuz, TIDAL, Amazon Music, and more. Users can also operate it via voice assistants like Alexa, Google Assistant, and Siri, or through the included remote control.

One of the standout features of the WiiM Amp Pro is its integrated room correction system, which analyzes room acoustics and optimizes sound reproduction based on speaker placement and environmental characteristics. Heat dissipation has been enhanced with a heatsink made from a copper, aluminum, and graphene alloy, ensuring stability even at high volumes and during extended listening sessions.

Compared to the standard WiiM Amp, the Pro model introduces numerous technical improvements that make it the superior choice for advanced performance seekers. The most significant upgrade is the implementation of the Post Filter Feedback (PFFB) circuit, which more effectively reduces distortion and provides better control over audio output. This results in greater sonic accuracy, regardless of the connected speakers' impedance.

The DAC section has also been upgraded: the WiiM Amp Pro features the ESS ES9038Q2M converter, a step up from the ES9018 found in the standard model. This upgrade offers a wider dynamic range and lower distortion. Additionally, wireless connectivity has been improved with the inclusion of Wi-Fi 6E and Bluetooth 5.3 with BT LE, ensuring greater stability in streaming. The dual-antenna setup further enhances reception and transmission speed compared to the single-module design of the base model.

Thermal dissipation has been re-engineered with the use of a copper, aluminum, and graphene alloy, representing a significant improvement over the standard WiiM Amp’s cooling system. This allows the Pro model to maintain high performance even under prolonged use. Lastly, the integration of HDMI ARC, absent in the standard model, makes the WiiM Amp Pro a more versatile solution for TV and home theater applications.

The WiiM Amp Pro stands as a major evolution over the base model, offering substantial enhancements in sound quality, processing power, connectivity, and thermal management. With its refined aluminum design, ability to drive a wide range of speakers, and uncompromising Hi-Res streaming support, it is an outstanding choice for those seeking a cutting-edge amplifier with advanced streaming capabilities.
