The Solo Uno is a streaming integrated amplifier by Arcam that delivers 25 watts x 2 channels into 8 ohms and 50 watts x 2 channels into 4 ohms. It was released in 2020. 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, so you can play digital sources directly with no separate DAC unit needed. The Arcam Solo Uno has an MSRP of $769.
There are 9 Arcam amplifiers in our database. Below you can see the main specs of these amps.
Arcam 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 Arcam Solo Uno is rated at 25 watts RMS into 8-ohms. Arcam provides this wattage at a THD (Total Harmonic Distortion) of 1% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 25 watts into 8-ohms (10 Hz-20 kHz) at 1%
- 50 watts into 4-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
- 117dB Signal to Noise Ratio

Which speakers suit the Arcam Solo Uno?
25 W into 8 ohms, 50 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?
Arcam Solo Uno is rated at 25 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 Arcam Solo Uno 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 Arcam Solo Uno Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the Arcam Solo Uno amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:
| Listening Environment |
Suitability |
| Near-field | Good |
| Small Room | Good |
| Mid-size Room | Average |
| Large Room | Poor |
| Very Large Room | No way |
Inputs and Outputs
Besides the performance specs of the Arcam Solo Uno, the next important feature set that you have to evaluate is the input and output selections that it offers.

Bluetooth Connectivity
Arcam Solo Uno doesn't have bluetooth connectivity feature. In order to stream your music via bluetooth, the easiest way is to connect an external bluetooth receiver to your Arcam Solo Uno. Two bluetooth receivers that we recommend are the
iFi Zen Blue V2 and the
Audioengine B1.
Among the amps in the same price range, these are the 5 amps that have Bluetooth Connectivity:
Phono Input
Arcam Solo Uno doesn't have a phono input so in order to play your vinyl albums, Arcam Solo Uno 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
Arcam Solo Uno 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 Arcam Solo Uno amp and your speakers.
DAC and Digital Music
The Arcam Solo Uno's built-in DAC allows the connection of digital sources directly, eliminating the need for an external DAC.
Arcam Solo Uno Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓Power nearly doubles into a harder load, 25 watts into 8 ohms rising to 50 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 117dB, so the amplifier itself should be inaudible between tracks.
- ✓Built-in DAC handling 24-bit / 192 and MQA, so a TV, computer or streamer can connect digitally with nothing in between.
- ✓Streams over the network without a separate streamer: Spotify Connect, Tidal, Qobuz, Apple Music and TuneIn; AirPlay 2, Chromecast built-in and Roon.
- ✓Pre-outs (Sub) leave room to add a power amplifier or an active subwoofer later.
- ✓At 142mm wide it fits where a full-size component will not.
- ✓5-year parts warranty, longer than most of the market.
- ✓Detachable mains lead (IEC 2-prong).
- ✗At 25 watts per channel it wants sensitive speakers; below about 87dB sensitivity you may run out of headroom in a large room.
- ✗Only 1 analogue input, so a second source means unplugging the first.
