F-07 Integrated Amplifier


    The Overview

    Striving for an all-encompassing sense of presence unmatched in its category, the F-07 Integrated
    Amplifier omits none of the remarkable performance features found in Esoteric’s flagship Grandioso
    separate amps. Richly capturing the full warmth and texture of music, all of the superb powers of
    expression and audio performance for which the Grandioso line has won renown are now condensed
    into an integrated form offering exceptional ease of use and broad appeal that more than compensates
    for its compact proportions.

    F-Series Philosophy: Basic and Complete

    Representing a new generation of integrated amplifiers, Esoteric's new F Series has been
    thoroughly invested with proven results gained in the development of our flagship Grandioso
    line of separate amplifiers. With the goal of capturing all the inherent warmth and texture of
    music, not only were the outstanding expressive powers of the Grandioso line pursued, the
    utmost limits of audio performance were also concentrated into an integrated configuration
    that offers excellent usability combined with an attractiveness that more than compensates for
    the limitations of their size. Basic and Complete. With sights set on creating a unique
    presence in the category, the Esoteric F Series is born.

The Features

A Fully Balanced Preamplifier

140x140

 One result of the lavish attention given to the development of the F Series is the preamplifier's fully balanced configuration, which derives from our highly esteemed C Series preamplifier models. Impervious to noise, it delivers pure and powerful signal amplification at ultra-low impedance.

Dual Monaural by Design

 Most clearly reflecting Grandioso thinking, the F-07's dual monaural configuration maintains complete left and right channel independence through all stages, from the preamplifier to the power amplifier's final stage. Outstanding circuit construction also yields excellent channel separation and sound quality to transcend the class.

ESOTERIC-QVCS

 Playing a significant role in the F-07's balanced dual monaural configuration is Esoteric's proprietary Quad Volume Control System (QVCS), which incorporates a total of four precision switched resistor ladder networks operating in unison to independently and electronically control the left and right channels and their positive and negative phases. This system helps maintain superb audio clarity, excellent channel separation and highly accurate phase characteristics. Further, by eliminating all volume control wiring on the audio board, the resulting shorter signal path minimizes deterioration of sound quality while realizing exceptionally low distortion.

Ultra-Low-Noise Logic Control

 As a countermeasure against noise, all control lines have been electronically separated from the main body of the preamplifier with the use of isolator elements integrated into the front panel.

High-Precision Ball Bearing Control Knobs

140x140

 Employing the same high-precision bearing mechanisms used in our Grandioso components, the F-07's volume control knob and selector switches offer exceptionally smooth operation with an analog feel free of mechanical play. Sparing no cost, all panel knobs have also been custom-machined from solid aluminum.

Dual Mono Phonostage Preamp

 The dual mono phonostage preamp (MM/MC) features independent left and right channel power sources and independent circuits.

High-Quality Headphone Amplifier

 The powerful headphone amp provides abundant output to effectively drive even difficult to power high-end high-impedance headphones.

2-Band (Treble/Bass) Tone Control

140x140

 Consisting of four circuits (L/R, –/+) for each band, the system's balanced dual monaural configuration enables the user to adjust tone settings free of any concerns about deterioration of sound quality. Shifting the variable bands more toward the high and low frequency ranges (14kHz/63Hz) permits fine tone adjustment without adversely affecting the original source signal. Fully electronic control also permits fine adjustment of up to ±12dB in 0.5dB steps.

Balanced Power Amplifier Input Stage

 With its balanced front stage, the power amplification section's clean amplification and low impedance further enhance the dynamic range.

Large-Capacity Custom Power Transformer - The Nucleus of the Finest Power Amplifiers

 The power supply features a large-core 633VA custom EI power transformer and 40,000µF block capacitors for each channel in its dual monaural configuration. Large-gauge cable used in all power connections helps minimize impedance to further ensure that every musical dynamic is faithfully reproduced by this outstanding power section.

Low Impedance for Enhanced Drive Capability

 The speaker output section employs eight 1mm-thick high-purity OFC bus bars and MOSFET switching with no mechanical contacts. Coils have also been eliminated from the output stage to minimize impedance and enhance drive capability.
