Squeeze every last detail from your record collection with our high-quality moving magnet and moving coil phono stage. Alva Duo delivers pure, immersive vinyl playback—whether through your hi-fi or straight to your headphones.

From the moment the needle touches down, Alva Duo enhances the vinyl experience with cutting-edge engineering, ensuring you can enjoy the purest analogue sound—whether through speakers or in private from the built-in headphone output.

The vinyl experience, refined

Designed for both moving magnet and moving coil cartridges, Alva Duo reproduces every record with unmatched clarity, warmth, and depth—just as it was meant to be heard.

Private listening, perfected

Late-night listening has never sounded better. Alva Duo’s built-in headphone amplifier lets you enjoy the full warmth of vinyl without turning on your hi-fi system. Just plug in and immerse yourself in pure analogue sound.

Lose the hum, keep the detail

Unwanted noise can cloud your records, but Alva Duo’s advanced switch-mode power supply eliminates hum by operating outside audible frequencies. Paired with a precision circuit design, it ensures crystal-clear playback, free from interference.

Alva Duo is kind to your records and to the planet too. With less than half a Watt of standby power consumption and an auto power-down feature after 20 minutes of inactivity, it’s efficient and universally compatible with voltages worldwide.

Features
  • Dedicated MM & MC phono preamp Supports both moving magnet and moving coil cartridges, offering greater flexibility and wider turntable compatibility.
  • Switch-mode power supply Alva Duo’s power supply switches outside audible frequencies to reduce hum and interference.
  • Surface-mounted circuit board Designed for pure signal transmission, ensuring exceptional clarity and the perfect listening experience.
  • 6.35mm headphone output Listen privately without needing a separate amplifier.
  • Auto power-down Alva Duo automatically switches off after 20 minutes of inactivity to conserve energy.
  • Subsonic filter Removes low-frequency rumbles from worn vinyl for a cleaner, more refined sound.
