The Amp Pro is a streaming integrated amplifier by WiiM that delivers 60 watts x 2 channels into 8 ohms and 120 watts x 2 channels into 4 ohms. It was released in October 2024. It is a 2-channel design using a Class D output stage. A minimum impedance of 4 ohms makes it compatible with a wide range of loudspeakers. It has a built-in DAC (ESS Sabre ES9032QM2), so you can play digital sources directly with no separate DAC unit needed. The WiiM Amp Pro has an MSRP of $379.
WiiM replaced the older WiiM Amp with this model. Follow the link to read our detailed comparison of these models:
Compare WiiM Amp Pro vs WiiM Amp
There are 4 WiiM amplifiers in our database. Below you can see the main specs of these amps.
WiiM Integrated Amplifier Series
Performance Specs
One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements. The WiiM Amp Pro is rated at 60 watts RMS into 8-ohms. WiiM provides this wattage at a THD (Total Harmonic Distortion) of 0.0005% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 60 watts into 8-ohms (20 Hz-20 kHz) at 0.0005%
- 120 watts into 4-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
- 105dB Signal to Noise Ratio

Which speakers suit the WiiM Amp Pro?
60 W into 8 ohms, 120 W into 4, rated down to 4 ohms.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
WiiM Amp Pro is rated at 60 watts into 8 ohms, which puts it in our Up to 60 watts band. The next band up is 61 to 90 watts, which is worth about 3.9dB more output. That is a real difference in headroom on peaks, and a modest one in how loud the system plays - power and loudness are not the same thing.
Before buying watts, check what your speakers actually need: the amp and speaker matcher works it out from their sensitivity, impedance and your room.
When pairing the WiiM Amp Pro with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.
What size of room is the WiiM Amp Pro Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the WiiM Amp Pro amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:

Bluetooth Connectivity
WiiM Amp Pro features built-in Bluetooth 5.3 for wireless music streaming from your Bluetooth-enabled devices such as Apple iPod/iPhone/iPad, Android smartphone/tablet, Windows PC, Mac computers/laptops.
Among the amps in the same price range, these are the 4 amps that have Bluetooth Connectivity:
WiiM Amp Pro supports the following Bluetooth Codecs when used with supported devices:
Bluetooth Transmitter:WiiM Amp Pro can also act as a Bluetooth transmitter, making it possible to stream the music from the amp to your bluetooth headphones or speakers.
Phono Input
WiiM Amp Pro doesn't have a phono input so in order to play your vinyl albums, WiiM Amp Pro has to be paired with a Phono Preamp that is MM (Moving Magnet) or/and MC (Moving COil) depending on your cartridge type.
Subwoofer Output
WiiM Amp Pro has a dedicated subwoofer output which can be used to connect it directly to a powered subwoofer via an LFE(Low Frequency Effects) cable.
Check our
Powered Subwoofers page to find a subwoofer that will work with WiiM Amp Pro amp and your speakers.
DAC and Digital Music
The WiiM Amp Pro's built-in DAC allows the connection of digital sources directly, eliminating the need for an external DAC. The DAC chip that is used in the Amp Pro is the
ESS Sabre ES9032QM2, and supports resolutions up to
32-bit, 192KHZ.
WiiM Amp Pro Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓Power nearly doubles into a harder load, 60 watts into 8 ohms rising to 120 into 4, which points to a power supply with real current in reserve.
- ✓Class D output stage, so it runs cool and wastes little power as heat - which is how it fits in a small case.
- ✓Signal-to-noise ratio of 105dB, so the amplifier itself should be inaudible between tracks.
- ✓Distortion is specified at 0.0005%, an order of magnitude below what is generally held to be audible.
- ✓Built-in DAC handling 32-bit / 192, so a TV, computer or streamer can connect digitally with nothing in between.
- ✓Digital inputs cover 1 optical and USB.
- ✓Streams over the network without a separate streamer: Spotify Connect, Tidal, Qobuz, Amazon Music and TuneIn; Chromecast built-in and Roon.
- ✓Bluetooth (version 5.3 and SBC, AAC, aptX-HD) for playing straight from a phone.
- ✓Pre-outs (Sub) leave room to add a power amplifier or an active subwoofer later.
- ✓Has tone controls.
- ✓At 191mm wide it fits where a full-size component will not.
- ✗Parts warranty is only 1 year.
