Devialet Astra Streaming Integrated Amplifier: A Modern Audio Marvel

Experience the versatile brilliance of the Devialet Astra streaming integrated amplifier, a true all-in-one wonder for audiophiles.

A Compact Powerhouse That Redefines Audio Components

When I first encountered the Devialet Astra streaming integrated amplifier, it was clear this wasn’t your average audio gadget. This sleek, compact device doubles as a streaming DAC, phonostage, stereo integrated amplifier, and can even function as stereo or monoblock amps. Devialet’s design philosophy boldly pushes the envelope, blending advanced DSP technology, noise-floor mastery, and an impressively flexible setup system. But before I get carried away with the sound, let’s rewind and peek into how Devialet marries form with function.

A Nod to Audio Innovators of the Past

My own journey into high-end audio began with a Bang & Olufsen Beomaster 2400 receiver. What grabbed me wasn’t just the stunning design, but B&O’s free-spirited approach to breaking norms — no cluttered knobs or buttons, just clean lines and clever engineering, like five tuners instead of preset buttons. Devialet channels this same rebellious spirit but takes it a step further. Since its 2007 inception, the brand has challenged audio conventions, and the $20,000 Astra is the latest embodiment of that legacy.

Design and Build: Understated Elegance with Serious Muscle

At first glance, the Astra looks like it belongs in a minimalist Scandinavian home—brushed metal, low-profile, and industrial chic that whispers luxury. That glowing round dial on top, which elegantly shows your volume and input, is a standout. The rear panel is discreetly tucked underneath to preserve the clean look. Despite its petite size, the Astra’s internals scream high-end performance. Every element, from the top-panel dial to the recessed back, reveals Devialet’s dedication to refined aesthetics and engineering precision.

Remote Control and Interface: Stylish, Functional, But Takes a Moment to Master

The Astra’s remote controller mirrors its sleek design—a square base topped with a silky smooth dial, communicating via two-way Bluetooth. A small screen on the remote means you don’t have to crane your neck to see the unit’s dial. It lets you adjust volume, skip tracks, play/pause, and switch inputs. The input-changing method isn’t the most intuitive—it took me a moment to get the hang of holding the play button to bring up inputs, then scrolling through—but once learned, it felt smooth and responsive with zero dropouts. Heads up, though: because it’s Bluetooth-based, third-party remotes won’t likely work here.

Configurator: Tailor Your Astra Experience

What really sets the Astra apart is its online configurator. You create an account, pick the Astra, then customize it to suit your setup. The back panel sports six RCA inputs, two optical TosLink ports, a USB, Ethernet, and two stereo binding post pairs. No balanced connections, likely due to space constraints, but the RCAs can be flexibly assigned—analog inputs with fixed or variable outputs, or SPDIF inputs in any combo. Once you finalize your dream setup, you upload it to the Astra via Devialet’s app. This configurator unlocks the Astra’s true shape-shifting potential.

Configuration #1: Streaming/DAC and Phonostage Setup

For my first test, I set the analog output fixed and routed it to my linestage preamp. The Astra is Roon Ready, so hooking it up for streaming was a breeze. The phonostage is pretty special too—you can pick your cartridge in the configurator, and it loads optimized settings for it, or you can fine-tune them yourself. Want to switch equalization curves on the fly? Go right ahead. It’s a level of customization you don’t often see in a single box.

Configuration #2: Integrated Amplifier with Subwoofer Crossover Mastery

Next, I used the Astra as an integrated amp in the family room, pairing it with Talon Hawk speakers and a JL Audio f110 subwoofer. The Talons gracefully roll off around 35–40Hz, so precise crossover control is crucial. Here’s where the Astra shines: I dialed in a 60Hz high-pass filter for the speakers and a 60Hz low-pass for the subwoofer. This allowed the sub to own the deep bass octaves, resulting in a soundstage that was clearer, tighter, and more dynamic—a rare feat for an integrated amp.

Devialet’s signature tech, Analog Digital Hybrid (ADH), combines Class A analog circuits with a Class D output stage, blending warmth and efficiency seamlessly.

Speaker Active Matching (SAM): The Secret Sauce

Devialet’s SAM technology uses time-alignment and speaker-specific filters based on real-world measurements. While my Talon Hawks weren’t in their database, experimenting with other profiles still made a noticeable difference—bass tightened up, timing improved, and distortion dropped without any hint of artificial DSP processing. You can adjust SAM’s intensity with a trim setting from –15dB to +15dB, tailoring how much flavor you want. It’s like having a personal audio engineer in your amplifier.

Monoblock Mode: Rethinking Stereo Amplification

Most amps just split their output into two separate channels for monoblocks. Not the Astra. When configured for monoblock mode, it uses a unique cross-linked interconnect layout that shares channel-specific info between units. This is pure Devialet philosophy: thinking of the signal path as a fully optimized system, not just a tweaked stereo setup. Though I didn’t get to fully test this mode, it’s an intriguing feature that hints at even more sonic potential.

Listening Impressions: Digital Streaming DAC Brilliance

Plugged in as a streaming DAC in my main rig, the Astra blew me away. Its noise floor was unbelievably quiet—“blacker than black”—which let delicate micro-details and spaciousness come through effortlessly. Cymbal decay was silky smooth, and transient and spatial cues were exceptionally precise. Despite its clarity, the Astra kept a warm, inviting tone without harsh edges or listener fatigue. I could happily listen all day. The bass was tight and well-defined, even if not the absolute lowest rumble I’ve heard. Boz Scaggs’ “Thanks to You” had just the right amount of deep bass—still highly satisfying.

Listening Impressions: Phonostage Performance

With the phonostage engaged, the Astra kept its quiet background, perfect for low-output moving-coil cartridges. My Airtight PC-1 Coda cartridge’s settings weren’t in the database, but a close model was, and the sound was smooth, relaxed, with excellent imaging and a wide soundstage. Dynamics were a touch reserved compared to high-end dedicated phonostages known for thunderous transient punch, but this is a genuinely capable phonostage built right into a multi-role powerhouse.

Listening Impressions: Integrated Amplifier Excellence

As an integrated amplifier, the Astra excelled in my family room setup. The crossover control allowed seamless fusion between Talon Hawks and JL Audio subwoofer, improving imaging, clarity, bass depth, and midrange openness. The noise floor stayed impressively low, and power delivery was robust and controlled. The system felt unusually cohesive and synergistic. Over longer sessions, I noticed a bit more upper-midrange grain here than in the media room—likely due to household power differences, not the amp itself.

Day-to-Day Use and Reliability

Using the Astra daily was a pleasure. It responded instantly to the Bluetooth remote, the app was rock solid, and uploading new configurations was quick and hassle-free. Heat was minimal, even during long listening sessions, and the system stayed rock steady. This level of reliability reinforces its premium price tag.

Summary: A Unique, Highly Capable Audio Transformer

The Devialet Astra isn’t just an integrated amplifier; it’s a one-of-a-kind configurable marvel. Its Roon-ready streaming DAC dazzles with detail and refinement, the phonostage adds genuine value, and as an integrated amp, it truly shines—especially with its advanced crossover and SAM technologies. For anyone wanting a single, elegant chassis that can adapt to multiple roles without compromising audiophile quality, the Astra is a rare gem.

Highly recommended.
