Bought these in my student days early 2000's, together with a Cambridge A1 amplifier (listing separately). Used quite a bit at the time and then put into storage after moving home. Good quality sound, but I do seem to remember the sound starting to distort/rattle at high volumes. One of the speakers has a slight scratch on it.
