Cambridge Audio Duo MM/MC Phono Stage

Whether you’re dusting off your record collection or embracing analogue through the vinyl revival, there’s a unique experience to be had from the moment you drop the needle on your favourite album. To preserve the unique warmth of the vinyl sound, the Duo phono preamplifier has been carefully designed with a state-of-the-art switch mode power supply and a new surface mounted circuit board layout to reduce unwanted noise.

Enjoy the warmth of vinyl privately thanks to Duo’s integrated headphone output. Uniquely, we integrated a 6.35mm headphone jack directly into the phono stage, so you can still enjoy your records when there’s no option to play out loud.

The integrated headphone output also means no need to turn on your amplifier just to power your headphones, resulting in a more eco-friendly listening experience.

If some records in your collection are a little worse for wear, the subsonic filter will help to eliminate low frequency rumbles that can be caused by imperfections within your vinyl. Combine this with the balance control for handling potential cartridge imbalances in your record player (that can cause a difference between the left and right channels) and the result is a detailed experience with accurate soundstage.
