      Vinyl as it's Supposed to Sound

      Whether youā€™re dusting off your record collection or embracing analogue through the vinyl revival, thereā€™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.

      Why Choose a Dedicated Phono Preamplifier?

      Due to the low-level signals created by a turntable, not all hi-fi amplifiers will let you connect directly to a record player. The phono preamplifier boosts this signal to something a power amplifier can work with. The challenge at this stage though is that noise can easily be added.

      This is why weā€™ve designed the Duo around exceptional components that deliver the warm and detailed sound thatā€™s synonymous with vinyl, all without distorting the signal from your moving magnet cartridge turntable. The switch mode power supply improves performance by switching outside of audible frequency to drastically reduce hum and new circuit board layout uses surface-mount components to reduce noise.

      Vinyl. Just for You

      Enjoy the warmth of vinyl privately thanks to Duoā€™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 thereā€™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.

      Attention to Detail

      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.

      Eco Friendly

      The Duo phono preamplifier is green at heart with less than half a watt standby power consumption and auto power down feature if the unit isnā€™t used after a 20 minute period. This in turn gives the unit the same worldwide voltage for compatibility wherever you are in the world.

      I dont know what I'm doing, but it sounds great

      I bought this to use Headphones on my Turntable. I'm using Denon High Output MC DL-110 and Sennheiser HD 660s2 with the Duo. First i pluged in on the MM like it should be and it was the best Sound i ever listen to. Then i tryed the HO MC on the MC in and the Sound is even better and more detailed. No Problem at all. I dont know why because i have absolutely no Idea what im doing. It sound great and im very happy to have this little pre/headphone amp.

      This is a brilliant piece of kit. I gave up hope that I could link my old 1970ā€™s high quality turntable until I found the ALVA DUO - it is a great design very simple to use and wonderful sound quality. The added bonus of the headphone socket is a good touch
