The heart of the preamp, the attenuator circuit, features the \"Ultra Fidelity Attenuator System\" used in the Grandioso C1X. This proprietary Esoteric system is designed with a high supply voltage to maximize dynamics and greatly improve the signal-to-noise ratio.

The volume and input select knob also function as mute and power switches, respectively, and the number of buttons on the front panel has been kept to a minimum in pursuit of a minimalist aesthetic.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cfigure class=\"col-md-8 col-md-offset-2\"\u003e\u003cimg width=\"401\" src=\"https:\/\/www.esoteric.jp\/images\/products\/_esoteric\/f-01\/f-01_vol_knob.jpg\" class=\"img-responsive\" alt=\"\" height=\"301\"\u003e\u003c\/figure\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pc-dsp\"\u003e\n\u003cdiv width=\"100%\" class=\"fixed-background background-4\"\u003e\n\u003ch3 align=\"center\"\u003eDual Mono Power Amplifier\u003cbr\u003e\u003cspan\u003e\u003cb\u003e– Design Overview –\u003c\/b\u003e\u003c\/span\u003e\n\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"scroll-background\"\u003e\n\u003cdiv class=\"container\"\u003e\n\u003cdiv class=\"future_description\" style=\"text-align: start;\"\u003e\n\u003cdiv class=\"col-md-10 col-md-offset-1\"\u003e\n\u003cdiv class=\"block-detail\"\u003e\n\u003cp\u003eWith the birth of the flagship Grandioso M1X and S1X amplifiers, the Esoteric amplifier design platform has been completely renewed.\u003cbr\u003eThe 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.\u003cbr\u003eThe power amplifier section of the F-02 follows the circuit design concept of the M1X, with a 120 WPC\/8Ω high-power design.\u003cbr\u003eFor amplifiers, the size of the power supply circuit is the most important point that directly affects the performance. The F-02 is 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 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cfigure class=\"col-md-10 col-md-offset-1\"\u003e\u003cimg width=\"401\" src=\"https:\/\/www.esoteric.jp\/images\/products\/_esoteric\/f-02\/f-02_interior.jpg\" class=\"img-responsive\" alt=\"\" height=\"301\"\u003e\u003c\/figure\u003e\n\u003cdiv class=\"col-md-12\"\u003e\n\u003cdiv class=\"block-title\"\u003eSubstantial Power Supply Comparable to a Separate Amplifier\u003c\/div\u003e\n\u003cdiv class=\"block-detail\"\u003e\n\u003cp\u003eThe power supply is the most important component in realizing a rich sound stage for amplifiers that constantly require large amounts of current, and the F-02 boasts extremely dynamic musical expression thanks to a unique power supply design that incorporates a great deal of Esoteric's expertise.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"block-title\"\u003eLarge Bare-Mount Power Supply Transformer\u003c\/div\u003e\n\u003cdiv class=\"block-detail\"\u003e\n\u003cp\u003eThe F Series uses the largest EI transformer that can be installed. By using a transformer that is much larger than the product originally requires to meet its output power, the F Series is able to follow dynamic changes in the power supply extremely well, resulting in a dynamic and open sound. In addition, suppressing transformer vibration also suppresses current flow.

High quality custom capacitors of Grandioso grade are used. A dual mono and parallel configuration of four 10,000μF capacitors per channel is used. The capacitors are operated in parallel by time difference to stabilize the current charging and discharging to the capacitors, thus ensuring the required large current supply at all times.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"block-title\"\u003eLess is More\u003c\/div\u003e\n\u003cdiv class=\"block-detail\"\u003e\n\u003cp\u003eIn the F Series, the signal path from the preamp to the power amplifier is as short as possible, and the bipolar transistor 3-parallel push-pull amplifier circuit is remarkably simple.\u003cbr\u003eThe phase compensation circuit is a minimal single-pole configuration, and the output stage is a coil-less design. By minimizing NFB (negative feedback), the circuit enhances the dynamics of the music. The minimalist circuit philosophy allows the harmonics (overtones), which are the most important but easily lost in the signal chain, to be preserved and the music to be reproduced like a real sound.\u003cbr\u003eAmplifiers generate a lot of heat, and internal temperature stability is extremely important. For this reason, we have optimized the location and circuitry of the temperature compensation circuit to stabilize the temperature of the entire amplifier block. This helps to speed up the stabilization of the idle current after the power is turned on and allows the transistors to operate at their best performance.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cfigure class=\"col-md-8 col-md-offset-2\"\u003e\u003cimg width=\"400\" src=\"https:\/\/www.esoteric.jp\/images\/products\/_esoteric\/f-02\/f-02_heatsink.jpg\" class=\"img-responsive\" alt=\"\" height=\"300\"\u003e\u003c\/figure\u003e\n\u003cdiv class=\"col-md-12\"\u003e\n\u003cdiv class=\"block-title\"\u003eLow Impedance\u003c\/div\u003e\n\u003cdiv class=\"block-detail\"\u003e\n\u003cp\u003eA 105μm thick-walled copper conductor is used for the substrate tracks, which are key to internal signal transmission quality. The eight bus bars in the power stage are luxuriously made of 1.0 mm high-purity OFC material. Important wiring from the primary side to the power supply section, drive stage, etc., is connected with ultra-thick cables with screw connections to eliminate connector losses. MOS FET switches without mechanical contacts are used in the speaker output section. Every detail has been carefully designed to reduce internal impedance. As a result, the amplifier is able to handle even large-diameter woofers, and has a driveability (damping factor: 500) that easily reaches the limit of the low-frequency range.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pc-dsp\"\u003e\n\u003cfigure class=\"col-md-12\"\u003e\u003cimg width=\"400\" src=\"https:\/\/www.esoteric.jp\/images\/products\/_esoteric\/f-02\/f-02_block_diagram_pc.jpg\" class=\"img-responsive\" alt=\"\" height=\"165\"\u003e\u003c\/figure\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col-md-12\"\u003e\n\u003cdiv class=\"block-title\"\u003eMechanical Perfection\u003c\/div\u003e\n\u003cdiv class=\"block-detail\"\u003e\n\u003cp\u003eTo achieve the single design goal of \"reproducing the master sound,\" the F-02 chassis optimally controls all vibrations that affect sound quality. The mechanical engineering of the F-02 is like that of a Formula 1 racing car, with the balance between rigidity and flexibility pushed to the limit. The heavy construction with a total mass of 32 kg, which is unprecedented for an integrated amplifier, shows the fullness and completeness of the product. The enclosure, which requires rigidity, makes extensive use of aluminum blocks to ensure non-resonance. On the other hand, the top panel has a semi-floating structure for an open sound. Esoteric's unique patented isolation foot, which integrates a spike and a saucer, also has a special structure to reduce mechanical stress.
