The "Finest" Integrated Amplifier You Could Ever Want - The new F Series integrated amplifiers are the culmination of a range of technologies designed to fulfill your ideals.
Incorporating all of the preamp and power amp developments from the flagship Grandioso "X" Edition, the new F Series integrated amplifiers deliver outstanding musicality that captures the rich textures of music in a single integrated amplifier. Despite the fact that the F Series is an integrated amplifier, it delivers a thorough quality and performance that will be the envy of all separate amp users. The F Series is the integrated amplifier that owners of Esoteric's K and N Series digital players have been waiting for, and it pushes the boundaries of integrated amplifier technology.
Balanced Dual Mono Preamplifier
The F-01/F-02 can also be expanded into a multi-amplifier system by connecting the S-05 power amplifier to the ES-Link Analog pre-outs. For even higher sound quality, an optional external power supply unit (to be announced) dedicated to the preamp can be connected. This unique design, which seems to contradict the integrated concept, is a testament to the F-01/02's high expandability and is the best proof that the built-in fully balanced dual mono preamp is designed with an uncompromising emphasis on quality.
Dual Mono Power Amplifier
The M1X monoblock and S1X Class A stereo amplifiers have captivated audiophiles around the world with their transparent, detailed and dynamic sound, and have become the new icons of high-end amplification.
The power amplifier section of the F-01/02 follows the circuit design concept of the S1X/M1X, with the F-01 being a 30 WPC Class A design and the F-02 being a 120 WPC high-power design.
For amplifiers, the size of the power supply circuit is the most important point that directly affects the performance. Both F-01 and F-02 are configured with dual monaural power supplies for all stages of the power rectification and smoothing circuits, and are equipped with a huge 940VA EI core power transformer, comparable to that of separate amplifiers. In addition, the "subtractive aesthetics" of advanced engineering cultivated in the M1X/S1X amplifiers is reflected in every detail of the amplifier design, including a simple and straightforward circuit design for rich harmonic (overtone) reproduction and powerful speaker drive capability through reduced internal impedance. The new F Series is designed to be the pinnacle of quality in terms of drive capability and sound quality, as good as separate power amplifiers.
