Cambridge Audio Alva Duo | Phono Preamp for Moving Magnet & Moving Coil Turntables
✓ ATTENTION TO DETAIL – The Alva Duo's switch mode power supply and surface mount technology delivers short signal paths and a faster response with precision and lower background noise so you don't hear a hum over the vinyl's low-level signals.
✓ SUBSONIC FILTER & BALANCE CONTROL – The Alva Duo will even work if your vinyls are a little worse for wear. The subsonic filter and balance control eliminate low frequency rumbles from imperfections in your vinyl for an accurate soundstage.
✓ HEADPHONE AMPLIFIER – Cambridge added a unique 6.35mm headphone jack directly into the phono stage so you can listen in private. The integrated headphone output also means no need to turn on your amplifier just to power your headphones.
