Product Description

Striving for an all-encompassing sense of presence unmatched in its category, the Esoteric 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.

Available with an optional D/A Converter board ($1,500 premium) offering USB, SPDIF and Optical input with PCM up to 32/384kHz and DSD 2.5, 5.6 and 11.2MHz.

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.

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 

High-Precision Ball Bearing Control Knobs 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 

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

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.

POWER AMPLIFIER SECTION 

POWER AMPLIFIER SECTION 

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 

Large-Capacity Custom Power Transformer

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 Output Stage Design 

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.

Powerful Bipolar Transistors Deliver 30 Amperes of Instantaneous Peak Output 

Powerful Bipolar Transistors

Large bipolar transistors deliver an outstanding continuous current capacity of 15A, and 30A of instantaneous peak power to ensure accurate reproduction of the most delicate tones.

Designed for System Upgrades 

The preamplifier and power amplifier sections of the F Series boast the same degree of refinement as Esoteric's separates, and can both be used as standalone devices, or even disabled if not in use. The PRE-out employs a powerful buffer amplifier. System upgrades can also be performed with no compromises in quality, and a card expansion slot facilitates the installation of an optional OP-DAC1 D/A Converter Board, which adds full compatibility with 11.2MHz DSD and 384kHz/32-bit PCM signal inputs. 

  • Organic EL display (Normal / Large font).
  • Two speaker terminal systems (A / B / A+B).
  • Independently adjustable input gains (±18dB; 0.5dB steps).
  • L/R channel balance.
  • Individually selectable phase inversion for each source.
  • AV through output (volume bypass) ensures seamless coexistence with AV systems.
  • RCA preamp output jack can be switched between PRE Out and REC Out.
  • Aluminum body remote controller can also be used to operate Esoteric's SACD players.
  • Displayed source device names can be programed.
  • Mute, dimmer and automatic display OFF functions.
