The Musical Fidelity M6x 250.7 is a high-end 7-channel Class A/B power amplifier offering 250 watts per channel into 4 ohms, with peak power of 400 watts. It features excellent technical performance with very low distortion (THD+N of 0.003% at 100W), a wide frequency response of 20Hz to 20kHz within 0.5dB, and a high signal-to-noise ratio of 105dB at 1kHz at 200W output. The amplifier is designed with seven mono amplifier modules, each with its own Class A/B stage, powered by two large toroidal transformers and extensive alloy heatsinking, ensuring silent operation without active cooling. Connectivity includes 7 line-level RCA inputs, 7 balanced XLR inputs, 7 RCA through outputs for bi-amping, 7 pairs of speaker terminals, and a trigger input/output for home theater integration. The unit measures 450 x 195 x 435 mm, weighs 32.5 kg, and supports multiple mains voltages (230V/115V internally set or optional 100V). It has a maximum power consumption of 2000-2500W depending on source, with standby power under 0.5W. The M6x 250.7 is praised for its natural sound, robust build quality, and ability to drive any loudspeaker with unconditional stability, making it suitable for demanding multichannel audio setups.
