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. Even though 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.
