The Raysonic M100 is a pair of mono-block amplifiers designed for high end audiophiles and dedicated music lovers. Our goal is to maximize the stability and yet minimize the requirements on maintenance. In order to achieve the highest quality in both technicality and music reproduction, our first priority in the circuit design is to achieve low noise and distortion and at the same time maintain a wide band frequency response in the amplifier. We have chosen 5881 power tubes as the core component of the class-A power amplification stage because when arranged effectively they produce this quality of sound whilst in ultra linear mode. This is because the 5881 uses a relatively low plate power which is about 23-25 watt. To achieve an output power of 100 watts in each mono-block, four pairs of 5881 beam power tubes are used. Using four pairs of 5881, we can reduce the plate resistance by 4 times and hence increase the damping factor of the amplifier and the slew rate of the speakers being driven by the amplifier. Most high end audio amplifiers use a plate cathode as a phase splitter. The drawback of this approach is that inconsistent output impedances occur between the positive and negative phase. Because of this, a plate cathode based design amplifier will have significant distortion in the high frequency range. The Raysonic M100 uses a cathode coupled phase splitter to avoid the problem mentioned above. The novel use of 5881 tubes in this configuration will provide Audiophiles and music lovers with the highest level of fidelity which cannot be found in any other amplifiers in the same price range.
