The Phono Box MM is a reliable, well-built phono stage with a discrete industrial design.Designed specifically to amplify your moving magnet cartridge output to Line level; the form factor of the unit is small and subtle, so it can be placed near the turntable or alongside your existing system without being intrusive.

The Phono Box MM accepts Moving Magnet cartridges only, and delivers a hi-fi music experience for an entry-level price.

The advanced circuitry keeps noise and distortion at a low level, while the sturdy metal case and outboard PSU reduce the risk of external interference. Input and Output sockets are gold-plated, to ensure the highest quality performance.
