Power and Dynamic Range That Stand Out

The F-05 was designed as a core component of Esoteric’s new F Series of Integrated
Amplifiers. Like the F-03A, its fully balanced preamplifier section was acquired from the
Grandioso C1, and its high-powered amplifier modules were acquired directly from the Grandioso S1.
As first seen in Esoteric’s premier models, the F-05 employs a complete dual-monaural
configuration through all stages of amplification, from preamplifier inputs to the final stages
of the power amplifier.
Highly recommended for those who value the exhilarating feel of music’s rich expression, the
F-05 provides the power to dynamically open any sound stage, and deliver exceptional levels
of performance when used in combination with any of Esoteric’s line of state-of-the art digital
players.

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

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

 The one design feature of these amplifiers that most clearly reflects Grandioso thinking is their dual monaural configuration, which maintains complete left and right channel independence through all stages, from preamplifier to the power amplifier’s final stage. As Esoteric integrated amplifiers, the major investments made in circuit construction expertise and materials developed over the years yield excellent channel separation and a measure of sound quality that transcends the class.

ESOTERIC-QVCS

 Playing a significant role in the F Series’ balanced dual monaural configuration is the proprietary Quad Volume Control System (QVCS), which incorporates a total of four precision switched resistor ladder networks operating in unison to electronically and independently 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 Series’ volume control knobs and selector switches provide exceptionally smooth operation with an analog feel free of any mechanical play. Sparing no cost, all panel knobs are also 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.

3-Band Tone Control (Treble/Middle/Bass)

140x140

 Commitment to achieving all the quality associated with high-end components results in a balanced dual monaural configuration consisting of four circuits (L/R, -/+) for each band. This system enables users to adjust tone settings free of any concerns about sound quality deterioration. Shifting the variable band more than usual toward the high and low frequency ranges (14kHz/63Hz) permits fine adjustment of bass and treble without adversely affecting the original source signal. Fully electronic control also permits fine adjustment of up to ±12dB in 0.5dB steps. The middle band can also be utilized as a loudness preset when set to the minus side and used in conjunction with the Tone Bypass switch.

Power Amplifier Input Stage Features Balanced Configuration

 The power amplification section’s front stage is balanced in line with the thinking behind our S Series separate amplifiers. Its low impedance and clean amplification further enhance the dynamic range.

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

 The power supplies of the F Series feature large-core 940VA custom EI power transformers and 40,000µF block capacitors for each channel in a dual monaural configuration. Large-gauge cable is used in all connections to help minimize impedance. As in our separate power amplifiers, this outstanding power section achieves a theoretically linear power output ranging from 120W at an 8Ω load to 240W at 4Ω for faithful reproduction of every musical dynamic.

Low Impedance for Enhanced Drive Capability

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

Esoteric

Since 1987, Esoteric has pursued a path dedicated to being a superior high-end audio/video brand focused on introducing components of the best value by merging innovative, proprietary recording and replay technologies. In order to meet the desires of musical and visual connoisseurs who are seeking new levels of excitement, Esoteric’s mission has been to continue to develop and release new products that improve upon the "state of the art", from highly acclaimed pure audio/video source devices to Super Audio CD and DVD components. Esoteric applied its no-compromise philosophy with the same intense consideration to its flagship Grandioso series to produce the next dimension of sound and audio immersion. With the Grandioso series, Esoteric sought to eradicate ANY distortions and colorations by taking a fresh look at entrenched norms and design elements, and by scrutinizing every last design detail – no matter how minute. All of the design tweaks, too numerous to elaborate here, yield an exceptional sonic purity that sweeps away distractions and enables listeners to experience an unprecedented level of musical detail and stunning visual presentation. Overture, as a provider of the “ultimate” audio/video products, is a select dealer for Esoteric and its Grandioso line.
