DetailsThe Musical Fidelity AMS100 is the first ever 50 watt pure Class A bridged amplifier. There are many advantages to a bridged amplifier; lower distortion and huge power supply noise rejection. These advantages are even more significant in a pure Class A configuration. The AMS100 has the same basic circuit as the AMS50 but even more of it. In fact it has precisely the same circuitry and number of output transistors as our monster Titan. The circuit configuration is unique and delivers excellent technical performance (more about technical matters below) and a beautiful sound. Power supply configuration Power supply configuration is usually the “poor relation” in amplifier design. Normally huge effort is put into the circuit and layout but the PSU configuration is taken for granted. Pure Class A amplifiers draw enormous current. This exposes any deficiencies in power supply design. This amplifier has a unique, never done before in the history of hi-fi, power supply design. Below are some circuit illustrations which show the major differences between this amplifier and any other amplifier.
