Cambridge Audio - Alva Duo - MC & MM Phono Preamplifier
Immerse yourself in the unique experience of vinyl with the Cambridge Audio Alva Duo MC & MM Phono Preamplifier—a pinnacle of moving magnet and moving coil phono stages. Meticulously designed to preserve the warmth of vinyl sound, it features a state-of-the-art switching mode power supply and a new surface-mounted circuit board layout, minimizing unwanted noise and revealing every detail.
Recognizing the challenge of low-level signals from turntables, the Duo boosts this signal without introducing noise. Exceptional components deliver warm and detailed sound synonymous with vinyl, without distorting the signal from your moving magnet cartridge turntable. The switch mode power supply minimizes hum, and surface-mount components reduce noise, ensuring a pristine audio experience.
Beyond the ordinary, the Duo features an integrated 6.35mm headphone jack directly into the phono stage, offering a private listening experience for the warmth of vinyl. The integrated headphone output eliminates the need to power on your amplifier just for headphones, contributing to a more eco-friendly listening environment. With enhanced features like a subsonic filter and balance control, the Alva Duo is a phono preamplifier that captures the soul of your record collection, elevating your vinyl journey.
