F-01 Class A Integrated Amplifier

Overview

The “Finest” Integrated Amplifier You Could Ever Want – The new F Series integrated amplifiers are the culmination of a range of technologies designed to fulfill your ideals.
Incorporating all of the preamp and power amp developments from the flagship Grandioso “X” Edition, the new F Series integrated amplifiers deliver outstanding musicality that captures the rich textures of music in a single integrated amplifier. Despite the fact that the F Series is an integrated amplifier, it delivers a thorough quality and performance that will be the envy of all separate amp users. The F Series is the integrated amplifier that owners of Esoteric’s K and N Series digital players have been waiting for, and it pushes the boundaries of integrated amplifier technology.

Features
