The F-01 is an integrated amplifier by Esoteric that delivers 30 watts x 2 channels into 8 ohms (Class A) and 60 watts x 2 channels into 4 ohms. It was released in 2024. It is a 2-channel design using a Class A output stage. Speakers connect via binding posts. A minimum impedance of 4 ohms makes it compatible with a wide range of loudspeakers. It also has a phono input, so a turntable can connect straight to it. The Esoteric F-01 has an MSRP of $21,000.
There are 2 Esoteric amplifiers in our database. Below you can see the main specs of these amps.
Esoteric Integrated Amplifier Series
Performance Specs
One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements. The Esoteric F-01 is rated at 30 watts RMS into 8-ohms. Esoteric provides this wattage at a THD (Total Harmonic Distortion) of 0.008% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 30 watts into 8-ohms (10 Hz-100 kHz) at 0.008%
- 60 watts into 4-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
- 104dB Signal to Noise Ratio

Which speakers suit the Esoteric F-01?
30 W into 8 ohms, 60 W into 4, rated down to 4 ohms.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
Esoteric F-01 is rated at 30 watts into 8 ohms, which puts it in our Up to 60 watts band. The next band up is 61 to 90 watts, which is worth about 3.9dB more output. That is a real difference in headroom on peaks, and a modest one in how loud the system plays - power and loudness are not the same thing.
Before buying watts, check what your speakers actually need: the amp and speaker matcher works it out from their sensitivity, impedance and your room.
When pairing the Esoteric F-01 with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.
What size of room is the Esoteric F-01 Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the Esoteric F-01 amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:
| Listening Environment |
Suitability |
| Near-field | Good |
| Small Room | Good |
| Mid-size Room | Average |
| Large Room | Poor |
| Very Large Room | No way |
Inputs and Outputs
Besides the performance specs of the Esoteric F-01, the next important feature set that you have to evaluate is the input and output selections that it offers.
Esoteric F-01 has total of 7 Analog inputs .

Bluetooth Connectivity
Esoteric F-01 doesn't have bluetooth connectivity feature. In order to stream your music via bluetooth, the easiest way is to connect an external bluetooth receiver to your Esoteric F-01. Two bluetooth receivers that we recommend are the
iFi Zen Blue V2 and the
Audioengine B1.
Phono Input
Esoteric F-01 features two Phono Inputs which are compatible with
MM (Moving Magnet) type of phono cartridges, you can connect your turntable with MM cartridges directly to this amp without the need for a phono preamp. If you are using an MC cartridge on your turntable, you need to use a phono preamp that has MC phono stage such as the
Cambridge Duo or the
iFi ZEN Phono.
Balanced connections
Esoteric F-01 has a balanced XLR input. A balanced cable carries the signal twice, on two conductors of opposite polarity. Interference picked up along the way lands on both equally and cancels when the two are recombined at the far end, so the longer the cable run and the noisier the surroundings, the more the connection is worth. Whether a balanced connection also yields more power depends on how the amplifier is built inside - some are balanced end to end, others convert to single-ended internally and deliver the same power either way, so it is worth reading the maker's own wording rather than assuming.
Esoteric F-01 Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓Power nearly doubles into a harder load, 30 watts into 8 ohms rising to 60 into 4, which points to a power supply with real current in reserve.
- ✓Damping factor of 500 means a low output impedance and firm control over a woofer.
- ✓Class A operation, the topology most often chosen where distortion at low levels matters more than efficiency.
- ✓Signal-to-noise ratio of 104dB, so the amplifier itself should be inaudible between tracks.
- ✓Distortion is specified at 0.008%, an order of magnitude below what is generally held to be audible.
- ✓7 analogue inputs, enough for a full rack of sources.
- ✓Phono stage built in (MM and MC), for moving-magnet and moving-coil cartridges alike.
- ✓Balanced XLR inputs, worth having on a long cable run.
- ✓Headphone output.
- ✓Has tone controls.
- ✓Made in Japan.
- ✗Class A runs hot and draws mains power whether or not it is playing; it needs room to breathe.
- ✗Analogue inputs only - a TV, computer or CD transport needs an external DAC.
- ✗No Bluetooth and no network streaming - everything arrives over a cable.
- ✗It weighs 32.2kg - check the shelf, and plan on a second pair of hands.

How much power does the Esoteric F-01 have?
The Esoteric F-01 delivers 30 watts x 2 channels into 8 ohms (Class A) and 60 watts x 2 channels into 4 ohms. Its output almost doubles into 4 ohms, which points to a strong power supply that can hold its composure with demanding, low-impedance speakers.
Does the Esoteric F-01 use vacuum tubes?
No. The Esoteric F-01 is a solid-state amplifier - there are no vacuum tubes in it.
What amplifier class is the Esoteric F-01?
The Esoteric F-01 uses a Class A amplifier design. Class A keeps its output devices conducting at all times for the lowest possible distortion, at the cost of considerable heat and low efficiency.
Does the Esoteric F-01 have a built-in DAC?
No. The Esoteric F-01 has no built-in DAC, so a digital source such as a streamer or CD transport needs its own converter, or you connect it over analogue.

Yes. The Esoteric F-01 has a built-in phono stage for MM AND MC cartridges, so a turntable can be connected directly without a separate phono preamp.
Does the Esoteric F-01 have Bluetooth?
No. The Esoteric F-01 does not have Bluetooth built in; you would need an external Bluetooth receiver connected to one of its inputs.
Does the Esoteric F-01 have a headphone output?
Yes. The Esoteric F-01 has a Yes-inch headphone output on the front panel for private listening.
How much does the Esoteric F-01 cost?
The Esoteric F-01 has a manufacturer's list price (MSRP) of $21,000.
