The H400 is a streaming integrated amplifier by Hegel that delivers 250 watts x 2 channels into 8 ohms in a dual mono configuration, rated at 1 kHz and 1% THD. It was released in September 2024. It is a 2-channel design using a Class A/B output stage. Speakers connect via binding posts. A minimum impedance of 2 ohms makes it compatible with a wide range of loudspeakers. It has a built-in DAC (Hegel bit-perfect DAC, 32-bit/384kHz over USB), so you can play digital sources directly with no separate DAC unit needed. The Hegel H400 has an MSRP of $7,700.
There are 7 Hegel amplifiers in our database. Below you can see the main specs of these amps.
Hegel 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 Hegel H400 is rated at 250 watts RMS into 8-ohms. Hegel provides this wattage at a THD (Total Harmonic Distortion) of 0.005% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 250 watts into 8-ohms (5 Hz-180 kHz) at 0.005%
- 100dB Signal to Noise Ratio
Built-in Sources
Most integrated amplifiers expect you to bring your own source. Hegel H400 does not:
- Internet radio radio built in.

We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
Hegel H400 is rated at 250 watts into 8 ohms, which puts it in our Over 180 watts band. That is the top band we cover, so there is no step up from here - if it is not enough, the answer is more sensitive speakers or a smaller room, not more watts.
When pairing the Hegel H400 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 Hegel H400 Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the Hegel H400 amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:
| Listening Environment |
Suitability |
| Near-field | Are you nuts? |
| Small Room | Bad |
| Mid-size Room | Poor |
| Large Room | Good |
| Very Large Room | Good |
Inputs and Outputs
Besides the performance specs of the Hegel H400, the next important feature set that you have to evaluate is the input and output selections that it offers.
Hegel H400 has total of 3 Analog inputs .
Inputs
- Total Number of Analog Inputs: 3
- 3 Optical Digital Input
- 2 Coaxial Digital Input
- USB Input:
- USB-B audio input
- 32-bit/384kHz
Outputs
- Speaker Outputs
- One unbalanced fixed and one unbalanced variable RCA line out Preamp Outputs
Bluetooth Connectivity
Hegel H400 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 Hegel H400. Two bluetooth receivers that we recommend are the
iFi Zen Blue V2 and the
Audioengine B1.
Among the amps in the same price range, these are the 5 amps that have Bluetooth Connectivity:
Phono Input
Hegel H400 doesn't have a phono input so in order to play your vinyl albums, Hegel H400 has to be paired with a Phono Preamp that is MM (Moving Magnet) or/and MC (Moving COil) depending on your cartridge type.
Subwoofer Output
Hegel H400 has Stereo RCA preamp outputs which can be used to connect to a powered subwoofer via an RCA cable ( as long as your sub supports this connection).
Check our
Powered Subwoofers page to find a subwoofer that will work with Hegel H400 amp and your speakers.
Balanced connections
Hegel H400 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.
DAC and Digital Music
The Hegel H400's built-in DAC allows the connection of digital sources directly, eliminating the need for an external DAC. The DAC chip that is used in the H400 is the
Hegel bit-perfect DAC, 32-bit/384kHz over USB, and supports resolutions up to
32-bit, 384KHZ.
Hegel H400 Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓250 watts per channel into 8 ohms is more than most rooms and most speakers will ever ask for.
- ✓Rated down to 2 ohms, so even a speaker with a punishing impedance dip is within its brief.
- ✓Damping factor of 4,000 means a low output impedance and firm control over a woofer.
- ✓Dual-mono construction, with the two channels kept separate through the power supply.
- ✓Signal-to-noise ratio of 100dB, so the amplifier itself should be inaudible between tracks.
- ✓Distortion is specified at 0.005%, an order of magnitude below what is generally held to be audible.
- ✓Built-in DAC handling 32-bit / 384, DSD and MQA, so a TV, computer or streamer can connect digitally with nothing in between.
- ✓Digital inputs cover 3 optical, 2 coaxial and USB.
- ✓Streams over the network without a separate streamer: Spotify Connect, Tidal and Qobuz; AirPlay, Chromecast built-in and Roon.
- ✓Pre-outs (One unbalanced fixed and one unbalanced variable RCA line out) leave room to add a power amplifier or an active subwoofer later.
- ✓Balanced XLR inputs, worth having on a long cable run.
- ✓Built-in Internet radio tuner.
- ✓App control.
- Nothing the published specs count against it.
