Audio T Verdict
The Hegel H400 is a powerful streaming integrated amplifier designed for ambitious two-channel systems that need substantial loudspeaker control without separating amplification, digital conversion and network streaming into several components.
Its dual-mono Class A/B power amplifier delivers 250W per channel into 8 ohms, remains stable into 2-ohm loudspeaker loads and has a quoted damping factor greater than 4000.
Those figures make the H400 a convincing option for demanding standmount and floorstanding loudspeakers, although sensitivity, impedance, room size and preferred listening level should still be considered before purchase.
Hegel's SoundEngine 2 technology monitors the amplifier output and applies local correction when distortion is detected. This is combined with DualAmp architecture, symmetrical dual-mono construction and a separate transformer for the DAC and pre-amplifier sections.
The built-in streaming platform supports Spotify Connect with Spotify Lossless, TIDAL Connect, Qobuz Connect, Google Cast, Apple AirPlay, UPnP, Roon Ready and JPLAY Certified playback. Internet radio and podcasts are provided through airable in the Hegel Control app.
Digital connectivity is equally comprehensive. USB supports PCM up to 32-bit/384kHz and DSD256 through DoP, while the BNC and RCA coaxial inputs support PCM up to 24-bit/192kHz and DSD64 through DoP.
The H400 has no phono stage, headphone output, Bluetooth, Wi-Fi, USB-drive input or HDMI connection. Vinyl requires an external phono stage, television sound normally uses optical audio and network streaming requires wired Ethernet.
One balanced XLR and two RCA analogue inputs are joined by fixed and variable RCA outputs. These allow the H400 to accommodate analogue sources, an active subwoofer, recording equipment or a suitable external power amplifier.
The BNC digital output and DAC-loop function provide a valuable upgrade path. The H400 can send its digital and streaming signal to the Hegel D50 Reference DAC, then receive the converted analogue signal through its balanced XLR input.
The less expensive H150 provides a built-in MM phono stage, headphone output and USB-drive playback, but has considerably less power. The H600 increases output to 303W per channel and provides additional analogue connectivity for still more ambitious systems.
For listeners who need the H600's broad approach but not quite its full power, size or price, the H400 is arguably the sweet spot within Hegel's premium integrated-amplifier range.
Hegel H400 Streaming Integrated Amplifier
The Hegel H400 combines a network music streamer, high-resolution DAC, analogue pre-amplifier and powerful dual-mono Class A/B power amplifier.
Connect a suitable pair of passive loudspeakers and the H400 can reproduce streamed music, computer audio, television sound, CD, an external turntable system and a wide range of conventional analogue or digital sources.
Source selection, volume, streaming and system settings can be controlled through the front panel, supplied RC8 remote, compatible streaming applications and the Hegel Control app.
250W-per-Channel Class A/B Amplification
The H400 produces 250W per channel into 8 ohms with both channels driven.
This substantial output gives the amplifier the headroom required for larger rooms, less sensitive loudspeakers and musical material with wide dynamic range.
Class A/B operation is used rather than a switching Class D output stage.
Power output alone cannot guarantee compatibility with every loudspeaker. A demonstration with the intended speakers remains the best way to assess control, tonal balance and achievable listening level.
Stable into 2-Ohm Loudspeaker Loads
Hegel specifies the H400 as stable into loudspeaker loads down to 2 ohms.
Loudspeaker impedance can fall considerably below its nominal figure at particular frequencies. An amplifier must supply additional current while remaining stable when this happens.
The H400's 2-ohm capability makes it suitable for consideration with demanding speakers, but room size, sensitivity and the complete impedance curve should still be assessed.
Damping Factor Greater Than 4000
The main power-amplifier stage has a quoted damping factor greater than 4000.
Damping factor describes the relationship between the amplifier's output impedance and the connected loudspeaker load.
A high figure can help the amplifier maintain electrical control over the movement of the loudspeaker drive units, particularly through the bass region.
The final bass performance will also depend on the loudspeaker design, cabinet, room acoustics and positioning.
Dual-Mono Amplifier Construction
The H400 uses a dual-mono power-amplifier layout with symmetrical left and right channels.
The two channels are arranged to reduce unwanted interaction between them and to maintain consistent performance when both channels are working hard.
This approach supports:
- Improved stereo separation
- More stable placement of voices and instruments
- Consistent current delivery to both loudspeakers
- Reduced channel-to-channel interference
- Greater control during complex musical passages
Hegel SoundEngine 2 Technology
SoundEngine 2 is Hegel's patented local error-correction system.
The circuit continuously monitors the amplifier's output and compares it with the incoming music signal.
When unwanted distortion is detected, an opposing correction signal is applied locally within the amplifier stage.
The system is intended to reduce:
- Crossover distortion
- Transistor distortion
- Dynamic distortion
- Errors created as loudspeaker impedance changes
Hegel's aim is to achieve the control normally associated with feedback while avoiding a conventional high level of global negative feedback around the complete amplifier.
DualAmp Technology
Hegel's DualAmp technology separates voltage amplification from current amplification.
The first stage increases the voltage of the incoming music signal. A separate current-gain stage then supplies the current required by the loudspeakers.
Keeping the sensitive voltage-gain circuitry away from the larger currents within the output stage is intended to reduce interference and distortion.
Separate DAC and Pre-Amplifier Power Supply
The DAC and pre-amplifier sections use a separate transformer rather than sharing every part of the main power-amplifier supply.
This helps isolate the low-level analogue and digital circuitry from the large and rapidly changing current demands of the loudspeaker output stage.
The result is intended to provide a quieter electrical environment for source selection, volume control and digital-to-analogue conversion.
Bit-Perfect Digital-to-Analogue Conversion
The H400 incorporates a high-performance bit-perfect DAC based on technology developed for Hegel's reference H600 amplifier.
The DAC is used by the built-in network player and the connected BNC, coaxial, optical and USB digital sources.
Hegel's digital design concentrates on signal timing, circuit layout, power-supply isolation and the analogue stage surrounding the converter.
High-Resolution Network Streaming
The wired network input supports compatible audio at resolutions up to 24-bit/192kHz.
Network playback includes support for:
- Spotify Connect
- Spotify Lossless
- TIDAL Connect
- Qobuz Connect
- Google Cast
- Apple AirPlay
- Roon Ready
- UPnP and DLNA
- JPLAY Certified playback
- airable internet radio and podcasts
The available quality depends on the streaming service, subscription, application settings, source material and network connection.
Spotify Connect and Spotify Lossless
Spotify Connect allows the H400 to receive music directly through the network while the Spotify application acts as the controller.
Hegel currently lists the H400 as compatible with Spotify Lossless.
The available audio quality depends on the customer's Spotify account, application settings and current service availability.

Spotify and other compatible streaming applications can communicate their current volume setting directly to the H400.
Always check the displayed volume before beginning playback, particularly when moving between headphones, mobile devices and the main Hi-Fi system.
TIDAL Connect
TIDAL Connect allows the H400 to be selected as the playback device within the TIDAL application.
The phone, tablet or computer controls playback while the amplifier receives the music directly through the network.
The available quality depends on the TIDAL subscription and playback settings.
Qobuz Connect
Qobuz Connect provides direct playback control through the Qobuz application.
Select the H400 from the list of compatible playback devices and the amplifier will receive the music through its wired Ethernet connection.
The selected subscription and quality settings determine the maximum playback resolution.
Google Cast
Google Cast allows compatible applications to send music directly to the H400.
Google Cast must first be enabled by accepting the relevant Google terms through the Hegel Control app.
Compatible Google Home functions can also provide multiroom and voice-control options.
Apple AirPlay
Apple AirPlay allows music and podcasts to be sent from a compatible Apple device or application to the H400.
The Apple device and amplifier must be connected to the same local network.
Compatible Apple Home functions can provide additional multiroom and voice-control options.
Roon Ready
The H400 is Roon Ready and can operate as a network-audio endpoint within a compatible Roon system.
Roon requires:
- A compatible Roon server
- An active Roon subscription
- A reliable home network
- A compatible controller device
Roon software and subscription are not included with the amplifier.
UPnP and DLNA Streaming
UPnP and DLNA allow the H400 to receive compatible music stored on the local network.
Music can be supplied by:
- A compatible NAS drive
- A computer running media-server software
- A dedicated music server
- A suitable UPnP control application
The selected server and application determine how albums, artists, playlists and folders are organised.
JPLAY Certified Playback
The H400 is JPLAY Certified and can be controlled through the compatible JPLAY application for iOS.
JPLAY can access locally stored network music and supported streaming services, subject to the application's current features and subscription requirements.
Other compatible UPnP applications can also be used.
airable Internet Radio and Podcasts
Internet radio and podcasts are provided through the airable catalogue within the Hegel Control app.
This gives access to stations and programmes from around the world without requiring a conventional FM or DAB aerial.
Station availability and programme listings are controlled by airable and the individual broadcasters.
Network Multiroom Playback
The H400 can form part of compatible multiroom systems using:
- Roon
- Apple AirPlay
- Google Cast
The required controller, accounts and compatible products depend on the selected platform.
Network stability becomes increasingly important when several zones are playing simultaneously.

- airable podcasts
- Network management
- Firmware information and updates
- Factory reset
The phone or tablet must normally be connected to the same network as the amplifier.
Wired Ethernet Network Connection
The H400 connects to the home network through its rear RJ45 Ethernet socket.
Wi-Fi is not built in. A network cable must run between the amplifier and a router, network switch or compatible wired network point.
A wired connection can provide greater consistency than Wi-Fi, particularly with high-resolution playback and several network products.
No Built-In Wi-Fi
The H400 requires wired Ethernet for streaming, app control and internet firmware updates.
A separate wireless bridge or mesh-network adaptor may provide an Ethernet connection where direct cabling is impractical, but stability should be confirmed before relying on it.
USB Computer Audio up to 32-bit/384kHz
The rear USB-B input allows a compatible Windows PC, Mac or dedicated music server to use the H400 as an external DAC.
Supported USB playback includes:
- PCM up to 32-bit/384kHz
- DSD64 through DoP
- DSD128 through DoP
- DSD256 through DoP
- MQA decoding up to 8x
The H400 must be selected as the audio-output device within the computer's sound settings or playback software.
No USB-Drive Input
The USB-B socket is intended for computer audio rather than direct playback from a flash drive or portable hard disk.
Music stored on a USB drive requires a suitable computer, music server, streamer or network-storage arrangement.
DSD Playback through DoP
The H400 supports DSD through DoP, or DSD over PCM.
DoP packages DSD data within a PCM-compatible transmission structure without converting the music into conventional PCM before it reaches the DAC.
Maximum support varies by connection:
- USB: DSD256 through DoP
- BNC coaxial input: DSD64 through DoP
- RCA coaxial input: DSD64 through DoP
- Network: DSD64
- BNC digital output: DSD64 through DoP
- Optical: DSD not listed
The source and playback software must support the appropriate transmission format.
MQA Decoding
Hegel currently lists MQA decoding up to 8x on the H400's network, USB, coaxial and optical digital inputs.
Compatible MQA material can be decoded to a displayed output rate of up to 352.8kHz or 384kHz.
Playback depends on the source file, service, software and digital connection.
True 75-Ohm BNC Digital Input
The rear BNC socket provides a true 75-ohm coaxial S/PDIF input.
BNC is designed to maintain the specified digital impedance more consistently than a conventional RCA connector.
The input supports:
- PCM up to 24-bit/192kHz
- DSD64 through DoP
- MQA decoding up to 8x
It is particularly suitable for compatible digital transports such as the Hegel Viking Reference CD Player.
RCA Coaxial Digital Input
A conventional RCA coaxial S/PDIF input is provided for compatible digital sources without a BNC output.
It supports:
- PCM up to 24-bit/192kHz
- DSD64 through DoP
- MQA decoding up to 8x
A correctly specified 75-ohm digital coaxial cable should be used rather than an ordinary analogue interconnect where possible.
Three Optical Digital Inputs
Three Toslink optical inputs accommodate compatible televisions, games consoles, streamers, CD players and digital radio tuners.
They support:
- PCM up to 24-bit/96kHz
- MQA decoding up to 8x
DSD is not listed as supported through the optical inputs.
Optical 3 is optimised to accommodate unstable digital signals that can sometimes be produced by television optical outputs.
Connecting a Television
A television with a suitable optical or coaxial digital output can connect to the H400.
The television should normally be configured for:
- Optical or digital audio output
- Stereo PCM or LPCM
- Internal speakers disabled where required
Use Optical 3 if the television produces intermittent sound or repeated dropouts.
No HDMI ARC or eARC
The H400 does not include an HDMI connection.
Television sound must be connected through a compatible optical, coaxial or analogue output.
Dolby Digital, DTS and other multichannel cinema formats should be changed to stereo PCM within the television settings.
Compatible Television Remote Control
The H400 can learn commands from many newer Samsung, Sony, LG and Philips television remotes.
Where compatible, the television remote can control:
- H400 volume
- Mute
- Automatic wake-up
- Selection of a chosen television input
- Standby through the appropriate mute command
Compatibility is not guaranteed with every television or remote-control model.
No Bluetooth Audio
The H400 does not include Bluetooth.
Wireless playback is provided through network platforms including AirPlay and Google Cast rather than a direct Bluetooth connection.
A separate Bluetooth receiver could be connected to one of the analogue or digital inputs where required.
One Balanced XLR Analogue Input
One electronically balanced stereo XLR input is provided for compatible analogue source equipment.
Suitable sources can include:
- High-quality CD players
- Standalone DACs
- Network streamers
- External phono stages
- Other balanced analogue components
The XLR input is also used as the return connection when adding the Hegel D50 through DAC-loop mode.
Two Unbalanced RCA Analogue Inputs
Two stereo RCA line inputs accommodate conventional analogue sources.
These can include CD players, external DACs, radio tuners, cassette decks and separate phono stages.
The H400 does not contain a built-in turntable phono stage.
Connecting a Turntable
A turntable requires a suitable external phono stage between its cartridge and the H400.
The required phono stage depends on whether the cartridge is:
- Moving magnet
- High-output moving coil
- Low-output moving coil
The external phono stage can connect to the balanced XLR input or either RCA line input, depending on the outputs it provides.
No Built-In Phono Stage
Do not connect a conventional turntable cartridge directly to an H400 line input.
A correctly matched external phono stage is required unless the turntable already provides a suitable line-level output.
Explore the Audio T turntable range to compare suitable vinyl sources.
Variable RCA Line Output
A stereo variable RCA output follows the H400 volume control.
It can be used with:
- A suitable external power amplifier
- An active subwoofer
- Compatible active loudspeakers
- Another volume-controlled system component
Gain structure and connection suitability should be checked before adding external amplification.
Fixed RCA Line Output
A separate fixed-level RCA output does not follow the H400 volume control.
It can be useful for:
- A recording device
- A second system with its own volume control
- Compatible monitoring equipment
- Another line-level destination
The Fixed Output Is Not Volume Controlled
Do not connect the fixed output directly to a power amplifier or active speakers without a separate safe volume-control stage.
Changing the H400 volume will not reduce the signal from this connection.
Adding an Active Subwoofer
The most common active-subwoofer connection uses the variable RCA output.
A suitable active subwoofer contains its own amplifier and line-level input.
Some models also support high-level loudspeaker connections and may be connected to the H400 speaker terminals where recommended by the subwoofer manufacturer.
Subwoofer level, crossover, phase and room position should be adjusted carefully to integrate with the main loudspeakers.
No Headphone Output
The H400 does not include a headphone socket or dedicated headphone-amplifier circuitry.
A separate headphone amplifier can connect to the fixed or variable RCA output, depending on the headphone amplifier's own facilities and the required volume-control arrangement.
Customers who require a built-in headphone output may wish to consider the Hegel H150 Streaming Integrated Amplifier.
Home-Theatre Input Mode
The H400's physical analogue and digital inputs can be configured for fixed high-level home-theatre operation.
This allows a compatible AV receiver, processor, streamer or multiroom controller with its own working volume control to feed the H400.
Fixed-Level Inputs Require Care
Home-theatre mode sets the chosen input to a high fixed volume.
Only connect a source with a functioning volume control. Connecting an ordinary fixed-output CD player, streamer or DAC could cause the system to play at an extremely high level.
Automatic Digital Input Sensing
The H400 can detect incoming signals on its BNC, coaxial, optical and network inputs.
The device menu can be configured to:
- Wake when network streaming begins
- Wake when a new digital signal is detected
- Switch automatically to an active digital input
- Return to the previously selected input when playback ends
Automatic behaviour can be changed or disabled to suit the system.
BNC Digital Output
A true 75-ohm BNC S/PDIF output sends compatible digital audio from the H400.
It supports:
- PCM up to 24-bit/192kHz
- DSD64 through DoP
- MQA up to 8x
The output can be used with a compatible external DAC or digital receiving device.
It can also be set to remain permanently active through the DAC-loop device-menu settings.
DAC-Loop Upgrade with the Hegel D50
DAC-loop mode allows the H400's streaming platform and digital inputs to remain in use while digital-to-analogue conversion is transferred to an external DAC.
A typical connection with the Hegel D50 Reference DAC uses:
- The H400 BNC digital output connected to the D50 BNC digital input
- The D50 balanced XLR outputs connected to the H400 balanced XLR input
- The D50 set to its BNC input
- DAC-loop mode enabled within the H400 device menu
The H400 retains network streaming, source selection and volume control, while the D50 performs digital-to-analogue conversion.
This provides a structured digital upgrade path without replacing the amplifier's streaming platform.
Automatic Firmware Updates
The H400 checks for and installs firmware updates through its wired network connection.
Updates are normally installed when the amplifier enters standby.
When Wake on LAN is enabled, updates can download and install while the amplifier remains in standby.
Critical updates may occasionally install immediately, including while the amplifier is operating.
Do not disconnect the mains or network cable while an update is being installed.
Adjustable Automatic Standby
The default automatic-standby period is approximately 15 minutes without music or with a very low signal at the loudspeaker outputs.
The device menu can change this to:
- 15 minutes
- One hour
- Disabled
Wake on LAN can remain active where the amplifier needs to respond to network streaming while in standby.
Maximum and Startup Volume Settings
The device menu allows a user-defined maximum volume to be set.
A separate maximum startup volume can help prevent the amplifier from powering on at an unexpectedly high level.
Streaming and USB applications may communicate their own volume setting to the H400, so the displayed level should still be checked before playback begins.
USB Volume Control
USB volume control can be enabled through the device menu for compatible computers and USB sources.
When active, changing the source-device volume can alter the H400's listening level.
Check the Computer Volume Before Playback
When USB volume control is enabled, the H400 can adopt the volume setting of the connected computer or USB source.
Confirm that the level is suitably low before pressing play.
OLED Display
The central OLED display shows the selected input, volume and relevant network or playback information.
Its brightness can be set to:
The display can also be switched off. It then illuminates temporarily when the volume or input is changed.
Front-Panel Controls
Two multifunctional aluminium controls sit on either side of the central display.
The left control selects the source and can be pressed to enter or navigate the device menu.
The right control adjusts volume and can be pressed for mute or playback functions where supported.
The power button is discreetly positioned beneath the front panel.
Hegel RC8 Remote Control
The supplied aluminium RC8 infrared remote can control the H400 and other compatible Hegel components.
For the H400, it provides access to:
- Power and standby
- Volume and mute
- Input selection
- Display control
- Playback commands
- Device-menu access
- Maximum and startup-volume functions
Control4 Custom-Installation Support
Hegel provides a Control4 driver for professional custom-installation use.
Installation and programming should be completed by an authorised Control4 specialist who can confirm compatibility with the wider automation system.
Substantial Full-Width Construction
The H400 uses a minimalist full-width enclosure with a precision-machined aluminium front panel, aluminium control knobs and ventilated upper casework.
Its substantial 20kg weight reflects the dual-mono amplification, power supply, heatsinking and supporting internal construction.
The amplifier is available in black.
Placement and Ventilation
Place the amplifier on a firm, flat and stable equipment support capable of carrying its 20kg weight.
Allow at least 10cm of open space around the rear, top and side panels, with the front remaining unobstructed.
Do not place the amplifier on:
- Carpet
- Rugs
- Fabric-covered furniture
- Unstable shelving
- Surfaces that obstruct the ventilation openings
Keep the amplifier away from moisture, excessive heat and direct sunlight.
