Esoteric F-01
The “finest” class A integrated amplifier incorporating Grandioso “X” Edition amp technologies.
The Esoteric F-01 “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.
Key Features
[Preamplifier Section]
- A fully balanced dual mono preamp in the direct line of the Grandioso C1X
- “Ultra Fidelity Attenuator System”, a stepped attenuator circuit developed by Esoteric
- Volume can be adjusted in 0.1dB/1,120* steps with our proprietary attenuator module “UFA-1792” *Preamp gain setting: at +12dB
- 3 inputs of “ES-Link Analogue”, a unique and proprietary current transmission system
- Two headphone outputs (balanced 4-pin XLR / unbalanced 6.3mm) with built-in fully balanced dual mono headphone amplifier
- Dual mono phono-stage preamp (RCA x 1, MM/MC)
- 3-band balanced tone control, independently adjustable for each input source
- ES-Link Analog(x1) /XLR (x1) pre-out for connecting the S-05 as an external power amplifier
- Dedicated DC power connector for connecting the PS-01F external power supply dedicated to the built-in preamp
- Preamp gain can be adjusted in 4 steps (0/+6/+12/+18dB) to match the connected power amplifier
[Amplifier Section]
