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.
A Fully Balanced Preamplifier
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
Dual Monaural by Design
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.
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
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
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
headphone amp provides abundant output to effectively drive even
difficult to power high-end high-impedance headphones.
2-Band (Treble/Bass) Tone Control
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
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
