Esoteric’s top-of-the-line integrated amplifiers, the F-01 and F-02, have been designed with the development results of the flagship Grandioso “X” Edition separate amplifiers to deliver outstanding musical expression in a single integrated amplifier. The PS-01F is an external power supply for the audio circuitry of the preamp section, designed to further enhance the sound quality of the F-01/F-02.
It is important that the preamp section, which handles small signals, and the power amplifier section, which sends large currents to the speakers, are not affected by each other. By adding the PS-01F to the F-01/F-02, the preamp’s capacitance is greatly increased and clearly separated from the amplifier’s main rectifier, allowing the user to enjoy the finest details and dynamics of music, reminiscent of the Grandioso C1X, our flagship preamp with a separate power supply.
