The Astra is a streaming integrated amplifier by Devialet that delivers 150 watts x 2 channels into 8 ohms, 300 watts x 2 channels into 4 ohms, and 1,000 watts peak over 1 ms. It was released in 2025. It is a 2-channel design using a ADH (Analog Digital Hybrid) output stage. Speakers connect via binding posts. A minimum impedance of 2 ohms makes it compatible with a wide range of loudspeakers. It has a built-in DAC (DAC Magic Wire with 192kHz/32-bit DSP), so you can play digital sources directly with no separate DAC unit needed. It also has a phono input, so a turntable can connect straight to it. The Devialet Astra has an MSRP of $20,000.
There are 3 Devialet amplifiers in our database. Below you can see the main specs of these amps.
Devialet 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 Devialet Astra is rated at 150 watts RMS into 8-ohms.
Here are the main highlights of its performance specs:
- 150 watts into 8-ohms
- 300 watts into 4-ohms
How loud will 150 watts actually play in your room? →

Which speakers suit the Devialet Astra?
150 W into 8 ohms, 300 W into 4, rated down to 2 ohms.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
Devialet Astra is rated at 150 watts into 8 ohms, which puts it in our 121 to 180 watts band. The next band up is Over 180 watts, which is worth about 2.3dB 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. Plenty of systems are better served by the 91 to 120 watts band and better speakers.
When pairing the Devialet Astra 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 Devialet Astra Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the Devialet Astra amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:
| Listening Environment |
Suitability |
| Near-field | Poor |
| Small Room | Poor |
| Mid-size Room | Good |
| Large Room | Good |
| Very Large Room | Average |
Inputs and Outputs
Besides the performance specs of the Devialet Astra, the next important feature set that you have to evaluate is the input and output selections that it offers.

Bluetooth Connectivity
Devialet Astra 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, there is only one Streaming speaker that have Bluetooth Connectivity:
Devialet Astra supports the following Bluetooth Codecs when used with supported devices:
Phono Input
Devialet Astra features two Phono Inputs which are compatible with
MM (Moving Magnet) type of phono cartridges, you can connect your turntable with MM cartridges directly to this amp without the need for a phono preamp. If you are using an MC cartridge on your turntable, you need to use a phono preamp that has MC phono stage such as the
Cambridge Duo or the
iFi ZEN Phono.
DAC and Digital Music
The Devialet Astra'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 Astra is the
DAC Magic Wire with 192kHz/32-bit DSP, and supports resolutions up to
24-bit, 384KHZ.
Devialet Astra Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓Power nearly doubles into a harder load, 150 watts into 8 ohms rising to 300 into 4, which points to a power supply with real current in reserve.
- ✓150 watts per channel into 8 ohms is more than most rooms and most speakers will ever ask for.
- ✓Rated down to 2 ohms, so even a speaker with a punishing impedance dip is within its brief.
- ✓Damping factor of 2,000 means a low output impedance and firm control over a woofer.
- ✓Built-in DAC handling 24-bit / 384, so a TV, computer or streamer can connect digitally with nothing in between.
- ✓Digital inputs cover 2 optical, 4 coaxial and USB.
- ✓Phono stage built in (MM/MC with 13 equalization curves and adjustable cartridge loading), for moving-magnet and moving-coil cartridges alike.
- ✓Streams over the network without a separate streamer: Spotify Connect, Tidal and Qobuz; AirPlay 2, Chromecast built-in and Roon.
- ✓Bluetooth (version 5.3 and AAC,SBC) for playing straight from a phone.
- ✓Pre-outs (Yes, mono or stereo) leave room to add a power amplifier or an active subwoofer later.
- ✓App control.
- Nothing the published specs count against it.
