The MP11 represents the first modern-day effort to utilize the proven superiority of the vacuum tube input stage connected to an amazing ICEPOWER® output stage. It uses a 12AU7 front-end tube. Its purpose is to provide the differential signal for true balanced operation. Tubes are superb in preamp stages – they are linear and circuits may be kept very simple. When the very frail signal coming from the source passes through very few devices that are inherently linear, less damage will be done.Careful attention has been given to the tube power supply. A stable, well-regulated power supply is used throughout the preamp section. The MP11 uses a three terminal IC voltage regulator to supply the heaters of the vacuum tube. This ensures that the cathodes of the tube are operated at a constant temperature regardless of the current AC line voltage. The characteristics of each triode section, and therefore the voltage gain of each amplifier stage, are strongly affected by the temperature of the cathodes. Regulating the voltage supplied to the heaters also helps to minimize tube generated noise in the circuitry. Regulation of the high voltage supplies is also necessary for optimum preamplifier performance.
