Whereas many Headphone Amplifiers and Phono Stages are built in China for sale in the west, Graham Slee Headphone Amplifiers are made in Britain, and China is our best customer! Our British made Phono Preamps are a world-wide favourite especially in Germany, Australia, USA and South East Asia. We export 70% of what we make to countries outside the UK and EU. Shouldn't that tell you something?
