VINYL AS IT’S SUPPOSED TO SOUND
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 Pre-amplifier 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 Pre-amplifier 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 we’ve designed the Duo around exceptional components that deliver the warm and detailed sound that’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.

The Duo seems to exude an air of accomplishment. It’s a solid, lightweight piece of tech that just looks plain good... A rich and rewarding listening experience I just can’t tear myself away from... Few other options out there can match this kind of listening experience, which to put it mildly, is pretty amazing.
