Esoteric F-05 Integrated Amplifier

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.

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. To capture all the inherent warmth and texture of music, not only were the outstanding expressive powers of the Grandioso line pursued, but 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.

• Full Analogue
  Analog amplification circuitry inherited from Esoteric's flagship Grandioso series for consistently superb sound quality.
• Fully Integrated
  Aspiring to be superior examples of the integrated amplifier format.
• Fundamental
  Invested with the finest materials and expertise in pursuit of the essence of amplifier design, while seeking uncommon sophistication and substance in the most basic format.
• Functional
  Offering more versatile tone control capability than separates, while bringing out the full potential of the integrated amplifier by providing ample functionality and abundant expandability in its overall refinement.
