Esoteric F-07 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
Virtually impervious to noise, the preamplifier's fully balanced configuration 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.
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, control board is housed in the front panel and electronically isolated from the main preamplifier board.
High-Precision Ball Bearing Control Knobs
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 phono equalizer (MM/MC) features independent left and right channel power supplies and independent circuits.
High-Quality Headphone Amplifier
The F-07's powerful headphone amp delivers ample output to effectively drive high-impedance headphones.
2-Band (Treble/Bass) Tone Control
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.
