Designed from the ground-up, the AM1 is a no-frills amp with just the basics but the best sound quality possible. There are no tone controls or fancy equalizers. No flashing lights or unnecessary sockets. What you get is four, line level inputs (1 with output), a balance control and a volume knob; oh, and what you also get is superb sound quality! By cutting back on the extras, Cambridge Audio have managed to retain high quality components.
