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. 30W + 30W (8Ω, Class A) 60W + 60W (4Ω) Ultra Fidelity Attenuator 3 × ES-Link Analog Inputs MM/MC Phono 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. FAQ — F-01 Is 30 watts enough for my speakers? 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. What is AV Through (volume bypass)? 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. Does it have a built-in phono stage? Yes. The F-01 includes an onboard MM/MC phono input for direct connection to a turntable (with standard grounding support).
