Esoteric F-01 Class A Integrated Amplifier

Balanced Dual Mono PreamplifierThe F-01 has been significantly upgraded from the previous F Series in terms of both functionality and sound quality, incorporating a number of new technologies from the development of the flagship Grandioso C1X preamplifier. The large-scale, balanced dual mono preamp comparable to a separate preamp, comes standard with three ES-Link Analog inputs that allow our proprietary current-based signal input from the Esoteric K/N Series digital source players for a live listening experience as if monitored directly from a recording studio analog console. The new F Series also features a unique "Ultra Fidelity Attenuator System", and the power supply section of the preamplifier has been further upgraded. Other key preamp features include a fully balanced headphone amplifier, dual mono phonostage preamp, and a high-quality 3-band balanced tone control.The F-01 can also be expanded into a multi-amplifier system by connecting the S-05 power amplifier to the ES-Link A
