Pure Class A authority • Fully balanced dual-mono preamp • Ultra Fidelity Attenuator System • MM/MC phono • AV Through (volume bypass)
The Esoteric F-01 Class A Integrated Amplifier is engineered as a reference-grade integrated for listeners who want the immediacy, tone density, and low-level resolution of pure Class A operation, paired with a fully balanced control section inspired by Esoteric’s flagship design philosophy. It combines a sophisticated preamp (with precision gain and balance control) with a robust Class A output stage for a presentation that is refined, dimensional, and exceptionally stable into real loudspeaker loads.
With 30W + 30W into 8Ω (Class A) and 60W + 60W into 4Ω, the F-01 emphasizes linearity and composure for high-resolution systems where texture, imaging, and control matter as much as outright wattage.
Class A power amplifier section — emphasizes linearity and continuous current delivery for natural tone and stable imaging.
Dual-mono rectification and smoothing — power supply stages are configured to support channel separation and dynamic consistency.
ES-Link Analog connectivity — proprietary current transmission interface for compatible Esoteric components and optimized signal transfer.
Tone control with precision — 3-band balanced tone control (treble/middle/bass), with independent adjustment per input source.
In short, the Esoteric F-01 Class A Integrated Amplifier is built to be the centerpiece of an analog-focused reference system, delivering Class A refinement with practical integration tools for modern listening rooms.
In Class A designs, the first watts are often where the most critical listening happens. The F-01 is an excellent match for efficient to moderately efficient speakers in small-to-medium rooms. For larger rooms or low-sensitivity speakers, pairing guidance is recommended.
AV Through allows a designated input to bypass the volume control, enabling the F-01 to function like a power amp for front channels in a home theater system while keeping your two-channel setup intact.
Yes. The F-01 includes an onboard MM/MC phono input for direct connection to a turntable (with standard grounding support).
