Quadraspire
"For over twenty years we have been enhancing the audio quality of our customers' Hi Fi systems worldwide. Established by Dutch designer Eddie Spruit in an East London studio in 1995, we have successfully expanded and now have a manufacturing facility south of Bath. This is where all of our design development and craftsmanship take place. To ensure quality sound performance we use the tried and tested technique of tuning by ear in the same way as the finest musical instruments are developed."
