Esoteric F-03A Integrated Amplifier

Audio expression, symphonic beauty, artistic passion, the concert hall's spatial feel, the excitement of the audience. Esoteric's Master Sound Works is an audio product concept that recreates all of the music information in original master recordings with the most state-of-the-art technology available today.

A Fully Balanced Preamplifier

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.

* QVCS: Quad Volume Control System

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

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)

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 30W at an 8Ω load to 60W 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.
