An external IFI Phono 3 preamplifier can make a real difference to your records - it's like moving from a basic TV to an 8K Ultra HD one, but for sound! It boosts sound quality, so everything comes through way stronger, clearer, and more lifelike. And you don't need any batteries or plugs because it gets both power and audio from whatever it's plugged into. Good to know - With its RIAA EQ, your music sounds balanced and crisp, no matter your choice of phones or computers - It supports both Moving Magnet (MM) and Moving Coil (MC) cartridges - The subsonic filter makes sure that you can enjoy your records without any rumbles and pauses.
