Audio T Verdict
The WiiM Amp Pro is a remarkably complete just-add-speakers system, combining high-resolution network streaming, capable stereo amplification, television connectivity, room correction and flexible subwoofer control in one compact enclosure.
Post-Filter Feedback, an improved DAC stage and stronger wireless connectivity distinguish it from the standard WiiM Amp, while its 60W-per-channel output remains best matched carefully to the chosen speakers and room.
The lack of AirPlay 2 will matter to some Apple households, but Google Cast, Alexa Cast, Roon Ready, two-way Bluetooth and the WiiM Home platform provide broad alternatives.
WiiM Amp Pro Streaming Amplifier
The WiiM Amp Pro combines a network music streamer, high-resolution DAC, pre-amplifier and Class D stereo power amplifier in one compact component.
Connect a suitable pair of passive loudspeakers and it can reproduce streamed music, television sound, network and USB libraries, Bluetooth audio and compatible analogue or optical sources.
Control is available through the WiiM Home app, supplied WiiM Voice Remote and multifunction front-panel rotary control.
60W-per-Channel Class D Amplification
A Texas Instruments TPA3255 Class D amplifier provides 60W per channel into 8 O or 120W per channel into 4 O.
This is sufficient for many stand-mount, floorstanding, in-wall, in-ceiling and outdoor passive speakers, although sensitivity, impedance, room size and preferred listening level remain important.
WiiM lists a minimum terminating impedance of 2.67 O, but unusually demanding or low-sensitivity speakers should still be discussed with Audio T before purchase.
Post-Filter Feedback Technology
Post-Filter Feedback, commonly shortened to PFFB, allows the amplifier to monitor the signal after the Class D output filter.
This helps maintain a more consistent frequency response as loudspeaker impedance changes, reducing the degree to which different speaker loads alter the amplifier's tonal balance.
It does not remove the need for appropriate speaker matching, but it helps the Amp Pro behave more consistently with a wider range of passive loudspeakers.
ESS ES9038Q2M DAC
Digital-to-analogue conversion is handled by an ESS ES9038Q2M DAC, with a quoted signal-to-noise ratio of 120dB and THD+N of 0.0005% at 5W.
Network playback, optical input, HDMI ARC and USB audio output support resolutions up to 24-bit/192kHz where the source and selected service allow.
The stereo RCA line input is converted to digital at up to 24-bit/192kHz so the signal can use volume control, EQ, RoomFit and multiroom distribution.
High-Resolution Network Streaming
The WiiM Home platform provides access to compatible music services, internet radio, podcasts, network libraries and files stored on a connected USB drive.
Supported technologies include Spotify Connect, TIDAL Connect, Google Cast Audio, Alexa Cast, Roon Ready and DLNA. Qobuz and other compatible services are also available through the WiiM Home platform.
Service availability can vary by region and some services require a separate subscription.
AirPlay 2 Is Not Supported
The WiiM Amp Pro does not support AirPlay 2, Siri or Apple HomePod grouping.
Apple phone and tablet users can still operate the amplifier through the WiiM Home app, Google Cast-enabled apps, compatible music-service apps and Bluetooth.
Wi-Fi 6E and Ethernet
Dual antennas and Wi-Fi 6E support provide a strong wireless-network connection where used with a compatible router and suitable signal coverage.
A wired Ethernet connection is also available and may be preferable where the equipment position has weak or congested Wi-Fi reception.
The Amp Pro can group with compatible WiiM products and supported Alexa or Google Cast devices for synchronised multiroom playback.
RoomFit Room Correction
WiiM RoomFit analyses how the connected speakers and room affect the frequency balance at the listening position.
Digital correction can then be applied to reduce the influence of particular room-related peaks and produce a more even response from the available speaker positions.
Room correction cannot compensate for unsuitable speakers or extremely poor placement, so the loudspeakers should still be positioned carefully before measurements are taken.
Per-Source EQ
The WiiM Home app includes preset profiles together with 10-band graphic and parametric equalisers for more detailed adjustment.
Separate settings can be retained for individual inputs, allowing television, streaming, optical, line-level and Bluetooth sources to use different tonal adjustments.
HDMI ARC and Optical Television Sound
HDMI ARC allows a compatible television to send sound to the Amp Pro through an HDMI cable, creating a higher-quality alternative to a conventional soundbar.
HDMI ARC and optical accept stereo PCM or Dolby Digital 5.1. In a conventional Amp Pro system, the soundtrack is reproduced through the connected front speakers and optional subwoofer.
Input auto-sensing can switch to the television or another connected source when an audio signal is detected.
DTS Is Not Supported
Set the television, disc player or connected source to output stereo PCM or Dolby Digital if no sound is heard.
Expandable WiiM Dolby 5.1 System
Current WiiM software allows the Amp Pro to operate as the front-left and front-right hub in a modular Dolby Digital 5.1 system.
Compatible WiiM devices can be assigned to centre and surround duties through the WiiM Home app, while a wired powered subwoofer or wireless WiiM Sub Pro can reproduce the low-frequency-effects channel.
A complete 5.1 arrangement requires additional compatible WiiM products, all connected to the same network. Supported combinations and firmware requirements should be checked when the system is planned.
Analogue Line Input
A stereo RCA line input allows a compatible CD player, tuner, cassette deck, external phono stage or another line-level source to be connected.
The input accepts up to 2Vrms and converts the signal to digital at up to 24-bit/192kHz for volume control, EQ, RoomFit and multiroom distribution.
A Phono Stage Is Required for Most Turntables
The RCA connection is a line-level input rather than a dedicated moving-magnet or moving-coil phono input.
A turntable must have a suitable phono stage built in or be connected through a separate external phono stage.
Powered Subwoofer Output
A 2Vrms mono RCA output allows a compatible powered subwoofer to be added.
The WiiM Home app provides bass-management settings, including an adjustable crossover from 30Hz to 250Hz, to help integrate the subwoofer with the main speakers.
The Amp Pro can also pair wirelessly with the WiiM Sub Pro through the WiiM Home app, providing more flexible placement without an RCA signal cable.
USB Library and USB Audio Output
The USB connection can read compatible FAT32, NTFS and EXT4 storage devices, making stored music available to the Amp Pro and other compatible WiiM or DLNA products.
It can alternatively provide UAC 2.0 USB audio output to a compatible external DAC or amplifier at up to 24-bit/192kHz.
Speaker, USB and Bluetooth outputs are selected through the WiiM interface rather than operating as independent listening zones. The optional subwoofer output can remain active with the selected main output.
Two-Way Bluetooth 5.3
Bluetooth 5.3 can receive music from a compatible phone, tablet, computer or television using the SBC or AAC codec.
The connection is bidirectional, allowing the Amp Pro to send audio to compatible Bluetooth headphones, earphones or wireless speakers.
There is no conventional wired headphone socket.
WiiM Voice Remote
The supplied Bluetooth remote provides standby, playback, volume, mute, source and four preset controls without requiring direct line of sight.
Its push-to-talk microphone supports compatible Alexa voice commands after the relevant account has been configured.
