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.

Vinyl, Just for You

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.
