Cambridge ALVA Solo Phono Preamp Description & Specifications by
Times Audio
Enjoy every last detail from your vinyl collection with our compact moving magnet phono stage, the Solo Phono Preamplifier.
From the moment the needle touches down, vinyl has a warmth and character all its own. Alva Solo preserves that distinctive sound with its cutting-edge engineering. Its advanced switch-mode power supply and surface-mounted circuit board eliminate unwanted noise, ensuring your records sound exactly as they should.
Turntable-ready performance
Many hi-fi amplifiers don’t support direct turntable connections. Alva Solo’s dedicated phono preamp ensures the low-level signal from your turntable is properly amplified—delivering a clean, rich, and balanced sound with every play.
Crystal clear playback
Alva Solo preserves the warmth and depth of vinyl with precision engineering. A switch-mode power supply reduces hum, and a refined circuit design minimises noise—so every note stays crisp, clear, and true to the original recording.
Balanced sound, no compromises
Wear and tear isn’t a problem for Alva Solo. The subsonic filter removes unwanted low-frequency rumbles from worn vinyl, while the balance control corrects cartridge imbalances. The result? A perfectly aligned soundstage and an immersive listening experience.
Alva Solo 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.
