Meridian 551

Excellent (closer to mint) condition Meridian 551 with manuals remote and phono stage.

he Meridian 551 Integrated Amplifier uses a dual-mono construction similar to the 556 and 557 Stereo Power Amplifiers but includes a high-quality preamplifier similar to the 501. The preamplifier provides six audio inputs, each of which can be individually adjusted for sensitivity, and identified on the four-character alphanumeric 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. A separate headphone amplifier and a speaker on/off facility allow you to enjoy music without disturbing others.
