With new components and materials, the sound quality is cleaner and more precise, while still retaining the smooth and richly detailed sonic signature that has made Arcam so popular over the past decades.
A treat for your turntable
Much more than just a box-ticking exercise, the Arcam A25’s built-in phono stage makes a top quality connection for your turntable. Suited to turntables with MM (Moving Magnet) cartridges, the high spec phono stage draws a deep seam of information from your vinyl, letting you hear subtle details from the music that might previously have been missed.
