- Balanced design
- WBT output terminals
Meridian's most powerful reference two channel amplifier has been designed and built to deliver the best possible Hi-Res audio performance from any high-quality passive loudspeaker system. Its low-feedback construction provides ultra-low distortion, ensuring an unparalleled level of clarity and transparency across the audible range. Effortless power delivery of 500W per channel into four ohms and bridgeable to >1.5kW mono into four ohms, the 857 features a totally new design for a Meridian power amplifier, borne out of extensive research, experience and a thorough understanding of psycho-acoustic principles.
The Meridian 857 includes five secondary transformer windings for maximum isolation between low power and high power parts. A ground plane design has also been used for optimal signal handling, while WBT output terminals have been provided to allow bi-wiring. Balanced and unbalanced inputs are provided, with unbalanced inputs converted to balanced before they enter the amplifier using Meridian’s proprietary ‘Superbal’ technology.
