Meridian 559 300W Two Channel Amplifier Meridian amplifier technology has been developed over many years with some remarkable landmark innovations. The core design of 559 employs a radical new amplifier topology which was created specifically to meet the demands of new audio formats, and which was first featured in Meridian’s DSP8000 flagship loudspeaker. The design goals for 559 were uncompromising. In particular superb linearity, stability and dynamic range are essential to do justice to high resolution source material from new formats like DVD-Audio and SACD. |

The 559 is an extremely powerful amplifier with an unruffled ability to continuously drive loads down to 1 ohm, and the capability of output current bursts exceeding 150 Amps. The power supply features a proprietary soft-start system, two low-noise high-mass 1.2kVA transformers and more than 80,000μF of audiophile-grade smoothing capacitance. Single-ended inputs are balanced using our proprietary ‘super bal’ input topology before being fed to the power amplifier. The amplifier design emphasizes ultra-low noise and distortion and zero output impedance before any feedback is applied. Each channel uses twenty 16-amp output devices in a super-class-A output stage and features Meridian’s proprietary dynamic bias system. These techniques result in sound which is secure and open on a wide variety of loudspeakers. |
