Musical Fidelity M8s500s Power Amplifier : Design + Build, something to Consider

The Musical Fidelity M8s500s Power Amplifier is a fully balanced stereo amplifier which delivers 500wpc, which almost doubles into 4ohms. The M8s-500s is engineered for very low distortion typically less than .001% of 1kz and below .005% at 20kHz. Even at the ridiculous level of 50kHz distortion is a mere 0.02% creeping up to around 0.06% at the even more unreasonable figure of 100kHz.

These may be measurements of frequencies never encountered in the real world but they prove a point; that the M8s-500s significant less distortion than rival designs.

Like the M8-700m the Musical Fidelity M8s500s Power Amplifier has very low noise. Its combination of huge power reserves, low distortion and low noise contribute to its effortless performance. It delivers everything from delicate detail to massive dynamic slam with incredible speed and precision. Whatever style of music you listen to the M8s-500s serves it up in a spacious sound stage with outstanding realism.
