Introduction

In choosing the 551 Integrated Amplifier you have acquired a component that combines major advances in audio and engineering design. It combines a full function preamplifier with a high performance power amplifier.

The preamplifier provides six audio inputs, each of which can be individually adjusted for sensitivity, and identified on the four-character alpha-numeric display. A very high quality MC or MM phono stage is available as an option for the dedicated LP input.

The power amplifier uses a unique feedback topology and precision local error correction system. It is designed and constructed in dual mono format, including a massive twin wound toroidal transformer.

This guide is designed to enable you to obtain the best possible results from the unit. If you have just purchased the 551 Integrated Amplifier you should first turn to the chapter Setting up the integrated amplifier, page 25, which explains how to unpack and install the integrated amplifier correctly.
