Meet the F-01

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.

Highlights & Benefits

• Pure Class A presentation — the Esoteric F-01 Class A Integrated Amplifier is designed for harmonic richness, low noise, and effortless micro-dynamics.
• Fully balanced dual-mono preamp architecture — improves separation and preserves signal purity from balanced sources.
• Ultra Fidelity Attenuator System — stepped attenuation enables extremely fine volume adjustment for precise level matching.
• Analog system flexibility — multiple balanced and single-ended inputs plus MM/MC phono for turntable systems.
• AV Through (volume bypass) — seamless integration with an AV processor/receiver for front-channel power in mixed music + theater systems.
• Dual headphone outputs — includes a 6.3mm unbalanced jack and a 4-pin XLR balanced output with a dedicated headphone amplifier stage.

Technology & Design

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.
