Integrated amplifiers — Devialet Astra

The Astra is a streaming integrated amplifier with built-in DAC and ADC from Devialet, a French manufacturer known for genuinely distinctive, compact high-power amplifier engineering combining digital and analogue technology within remarkably small chassis designs. The Astra represents Devialet's current flagship expression of that core engineering philosophy, packing substantial capability into a genuinely space-efficient enclosure.

Key specs that matter

Two balanced XLR inputs and one single-ended input are provided. Output power is 2 x 150W into 8 ohms, doubling cleanly to 2 x 300W into 4 ohms - a textbook power doubling indicating a robust, well-regulated power supply. Frequency response spans from DC (0Hz) to 88,000Hz within plus-or-minus 3dB, a genuinely exceptional bandwidth extending all the way down to true DC coupling. Signal-to-noise ratio reaches 117dB, with total harmonic distortion plus noise at an exceptionally low 0.0006%, and an extraordinary damping factor of 2,000 - among the highest figures achievable with current amplifier technology, reflecting Devialet's characteristic hybrid analogue-digital amplification approach. At just 386 x 386 x 47mm and 7.2kg, the Astra maintains an astonishingly compact, slim footprint for its considerable output and feature set.

Sound and use context

Expect exceptional control and precision reflecting the extraordinary damping factor of 2,000 - Devialet's characteristic hybrid amplification technology, combining Class A and Class D circuit elements, is specifically engineered to deliver the tonal warmth of Class A with the efficiency and compact size Class D circuitry allows.

Pairing

Both balanced XLR inputs and the built-in ADC and DAC cover a genuinely wide range of analogue and digital sources directly, and the astonishingly compact, slim chassis fits into spaces where a conventional full-size integrated amplifier simply would not.

Alternatives

Devialet's broader Phantom and Expert Pro product lines offer alternatives within different form factors and price points, worth comparing directly if the Astra's specific balance of streaming, amplification and connectivity doesn't precisely match a particular system's needs. Devialet's continued innovation within genuinely compact, high-power integrated amplifier design has established the brand as a distinctive alternative to more conventional full-size separates-based systems, a positioning the Astra extends into the company's current flagship offering. Recommended overall for buyers seeking genuinely space-efficient, high-performance streaming amplification.
