The M8-700 has received outstanding reviews and an enthusiastic reception from knowledgeable audiophiles. The combination of high power and cutting edge technical performance has proved a compelling combination. However some customers do not have the space for two large monoblocs and do not necessarily need that much power. For them we have designed the M8-500s. Pairing it with the matching M8 Preamp gives an amplification system fit of the highest levels of reproduction M8-500s - Design and Build The M8-500s is a fully balanced stereo amplifier which delivers 500wpc, which almost doubles into 4ohms. The M8-500s 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 M8-500s significant less distortion than rival designs. Like the M8-700m the M8-500s has very lose 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 M8-500s serves it up in a spacious sound stage with outstanding realism. Its power and balance mean that the M8-500s can drive just about any loudspeaker you choose. It is, of course, the perfect partner/visually and sonically for our M8 preamp.
