Audio T Verdict
The Marantz MODEL 70 is a traditional two-channel integrated amplifier brought thoughtfully up to date for modern living rooms.
Its 50W-per-channel current-feedback amplifier provides a useful increase over the long-running PM6007, while a toroidal transformer, linear-drive power supply, Marantz HDAM-SA3 circuitry and carefully selected components show that its design remains firmly rooted in proper Hi-Fi engineering.
Connectivity is particularly well judged. Three analogue line inputs and a moving magnet phono stage cover conventional sources, while an ESS Sabre DAC serves the optical, coaxial and HDMI ARC inputs. A television can therefore use the main stereo system through one HDMI cable without turning the MODEL 70 into a complicated multichannel receiver.
Bluetooth with aptX, aptX HD and aptX Adaptive provides convenient wireless playback from compatible phones, tablets and computers. The amplifier can also transmit sound to compatible Bluetooth headphones, alongside its conventional front-mounted wired headphone output.
A stereo pre-amplifier output and dedicated subwoofer output provide useful expansion options, while Source Direct allows the bass, treble and balance circuits to be bypassed when a simpler signal path is preferred.
The MODEL 70 is deliberately not a network-streaming amplifier. There is no HEOS, Wi-Fi, Ethernet, AirPlay or USB music playback. Customers wanting those facilities should consider the MODEL 60n or MODEL 40n instead.
For listeners who already own a streamer, want simple Bluetooth playback or primarily use vinyl, CD and television sound, the MODEL 70 offers an appealing balance of traditional Marantz musicality and genuinely useful modern connectivity.
Marantz MODEL 70 Integrated Stereo Amplifier
The Marantz MODEL 70 is a two-channel Class AB integrated amplifier designed to control analogue and digital sources while providing the power required by a pair of passive loudspeakers.
It delivers 50W RMS per channel into 8 ohms and 65W per channel into 4 ohms. The current-feedback amplifier design, HDAM-SA3 circuitry, toroidal transformer and linear-drive power supply are intended to provide clarity, stability and musical control across a broad selection of loudspeakers.
Three line-level RCA inputs, a moving magnet phono stage, optical and coaxial digital inputs, HDMI ARC and aptX Adaptive Bluetooth allow turntables, CD players, streamers, televisions and mobile devices to share one stereo system.
A front headphone output, Bluetooth headphone transmission, stereo pre-amplifier output and dedicated subwoofer connection add flexibility without complicating everyday operation.
No Network Streaming Is Built In
The MODEL 70 supports Bluetooth audio but does not contain Marantz HEOS network streaming.
A separate network music streamer is required for services such as Spotify Connect, TIDAL Connect, Qobuz Connect, internet radio, AirPlay or music held on a NAS drive.
- No HEOS Built-in
- No Wi-Fi connection
- No Ethernet connection
- No AirPlay
- No network music services
- No USB music playback
- No USB computer-audio input
50W-Per-Channel Class AB Amplification
The MODEL 70 delivers 50W RMS per channel into an 8-ohm loudspeaker load and 65W per channel into 4 ohms.
This provides a useful level of power for many modern standmount and floorstanding loudspeakers in small and medium-sized rooms.
Published wattage does not tell the complete story. Loudspeaker sensitivity, minimum impedance, crossover behaviour, room size and listening distance all affect how hard an amplifier must work.
The MODEL 70's high-current design is intended to retain composure as musical demands increase, rather than simply producing an impressive headline figure under undemanding test conditions.
Current-Feedback Amplifier Design
Marantz uses a current-feedback topology within the MODEL 70's amplifier stages.
Current-feedback circuits can provide wide bandwidth and a fast response to changing musical signals. Marantz has used the approach across many of its established integrated amplifiers and premium separates.
The design is intended to preserve low-level detail and transient information while maintaining stability with a suitable loudspeaker load.
Marantz HDAM-SA3 Circuitry
The MODEL 70 uses Marantz HDAM-SA3 modules within its low-level amplifier circuitry.
HDAM stands for Hyper Dynamic Amplifier Module. Rather than relying solely on conventional integrated operational-amplifier chips, Marantz builds these stages from individually selected components.
This allows the circuit layout, component values and operating behaviour to be tuned as part of the complete amplifier rather than being determined entirely by an off-the-shelf integrated device.
The MODEL 70 also uses selected high-grade and customised components in areas considered important to sound quality.
Toroidal Power Transformer
A toroidal transformer supplies the MODEL 70's amplifier and control circuitry.
Toroidal transformers can provide strong current delivery from a relatively compact package while producing less external magnetic leakage than many conventional transformer shapes.
The transformer is partnered with a linear-drive power supply and fast Schottky rectifier diodes.
This provides the amplifier stages with a stable supply while helping reduce switching noise from the rectification process.
Linear-Drive Power Supply
The MODEL 70 uses a linear-drive power-supply arrangement rather than a lightweight external adaptor.
The internal supply supports the amplifier's ability to respond to sudden musical peaks and changing loudspeaker demands.
Separate attention has also been given to the lower-level analogue, digital and control circuitry so that the amplifier is not relying on one undifferentiated supply arrangement.
Aluminium Extrusion Heatsink
A solid aluminium extrusion heatsink removes heat from the Class AB output stage.
The amplifier will become warm during normal use, particularly at higher listening levels or when driving lower-impedance loudspeakers.
This is expected, but the MODEL 70 still requires free airflow around its case.
Allow Adequate Ventilation
Do not install the MODEL 70 inside a tightly enclosed cabinet or place another heat-producing component directly on top.
Leave open space around the sides and above the amplifier so that heat can escape naturally.
Loudspeaker Matching
The MODEL 70 is suitable for a wide variety of domestic standmount and floorstanding loudspeakers, but matching should be based on more than nominal impedance alone.
Consider the following:
- Loudspeaker sensitivity
- Nominal and minimum impedance
- Crossover complexity
- Recommended amplifier power
- Room size
- Listening distance
- Preferred listening level
- Whether a subwoofer will be used
A demonstration with the intended loudspeakers provides the best indication of whether the MODEL 70 offers the required control, scale and volume.
One Pair of Loudspeaker Outputs
The MODEL 70 provides one stereo pair of gold-plated metal binding posts.
The terminals accept common loudspeaker-cable terminations, including suitably prepared bare wire, spade connectors and compatible 4mm plugs.
Unlike some earlier Marantz amplifiers, it does not provide separately switched Speaker A and Speaker B outputs.
Check Loudspeaker Polarity
Connect the positive amplifier terminal to the positive loudspeaker terminal and repeat the same arrangement for the negative connection.
Reversing the polarity of one speaker weakens central imaging and can reduce bass impact.
Three Analogue Line Inputs
Three stereo RCA line inputs are provided for conventional analogue source components.
The rear-panel inputs are labelled CD, Line 1 and Line 2.
Suitable sources can include:
- A CD or SACD player
- A network streamer with analogue outputs
- A standalone DAC
- A radio tuner
- A cassette deck
- An external phono stage
- A television with a suitable analogue output
The specified high-level input sensitivity is 185mV with an input impedance of 18k ohms.
Built-In Moving Magnet Phono Stage
A dedicated moving magnet phono input allows a compatible turntable to connect without requiring a separate phono stage.
The input is specified at 3.1mV sensitivity with a standard 47k-ohm resistance.
This makes it suitable for many conventional moving magnet cartridges and some high-output moving coil designs intended for MM loading.
A grounding terminal is provided for turntables and tonearms with a separate earth lead.
No Low-Output Moving Coil Input
The internal phono stage is intended for moving magnet cartridges.
A low-output moving coil cartridge requires a suitable external MC phono stage or correctly matched step-up arrangement connected to one of the MODEL 70's line inputs.
Connecting a Turntable with a Built-In Phono Stage
A turntable with an internal phono stage should normally connect to one of the CD or Line inputs rather than the dedicated Phono input.
Set the turntable to its line-level output mode where applicable.
Sending an already amplified line-level signal into the MODEL 70's phono input will apply excessive gain and RIAA equalisation a second time, producing severe distortion.
ESS Sabre Digital-to-Analogue Converter
The optical, coaxial and HDMI ARC inputs feed an internal ESS Sabre digital-to-analogue converter.
Compatible digital signals are supported up to 24-bit/192kHz.
The DAC allows compatible televisions, CD transports, streamers, games consoles and other digital equipment to use the MODEL 70's analogue pre-amplifier and power-amplifier stages.
The exact ESS DAC model is not specified in Marantz's published information.
Optical Digital Input
A Toslink optical input provides a completely electrically isolated connection from a compatible source.
It can accommodate products such as:
- A television
- A CD transport or player
- A network music streamer
- A games console
- A digital radio tuner
Compatible two-channel PCM is supported up to 24-bit/192kHz.
Coaxial Digital Input
A gold-plated RCA coaxial input provides an alternative digital connection for a compatible source.
Use a correctly specified 75-ohm digital coaxial cable rather than a conventional analogue RCA interconnect where possible.
Compatible two-channel PCM is supported up to 24-bit/192kHz.
Automatic Power-On from a Digital Source
The MODEL 70 can wake automatically when a compatible signal is detected at a digital input.
This is particularly useful when the amplifier is connected to a television or another source used regularly.
Operation can depend on the chosen input, source settings and standby configuration.
HDMI ARC for Television Sound
HDMI ARC allows a compatible television to send stereo audio to the MODEL 70 through one HDMI cable.
This lets television programmes, films, streaming-video applications and games use a pair of proper Hi-Fi loudspeakers.
The MODEL 70 is a two-channel stereo amplifier rather than a multichannel AV receiver. It does not decode Dolby Atmos, DTS:X or conventional surround-sound formats.
Set the Television to Stereo PCM
Set the television's digital-audio format to PCM or stereo if no sound is heard.
The HDMI cable must connect to the television socket marked ARC or eARC. Available control functions can vary between television manufacturers.
HDMI ARC Without Video Switching
The MODEL 70 has one HDMI ARC connection dedicated to receiving television audio.
It is not an AV receiver and does not provide additional HDMI inputs for games consoles, disc players or video-streaming boxes.
Those devices should connect directly to the television, which then returns their audio to the MODEL 70 through ARC.
Bluetooth with aptX Adaptive
Bluetooth provides convenient wireless playback from compatible phones, tablets and computers.
Marantz lists support for aptX, aptX HD and aptX Adaptive alongside standard Bluetooth operation.
aptX Adaptive can alter its transmission behaviour according to the source, connection conditions and audio material, provided the transmitting device also supports the codec.
Bluetooth is useful for everyday listening, podcasts, radio applications and guests. A dedicated network streamer or wired digital source may still provide greater consistency and higher maximum resolution.
Bluetooth Headphone Transmission
The MODEL 70 can send audio wirelessly to compatible Bluetooth headphones.
This allows connected sources to be heard privately without running a headphone cable across the room.
Bluetooth headphone volume can be adjusted through the amplifier.
Wireless headphone performance, latency and available codecs depend on the headphones and surrounding wireless conditions.
Bluetooth Transmission Is Not Multiroom Streaming
The Bluetooth headphone feature sends audio to a nearby compatible listening device.
It does not provide HEOS multiroom playback or network synchronisation with other Marantz products.
Front Wired Headphone Output
A full-size headphone connection is positioned on the front panel for conventional wired Hi-Fi headphones.
The main volume control adjusts the headphone listening level.
Reduce the volume before connecting or changing headphones, as different models can produce very different sound levels from the same setting.
Bass, Treble and Balance Controls
Front-panel bass, treble and balance controls allow the tonal balance and stereo position to be adjusted.
The bass control provides adjustment of plus or minus 10dB at 50Hz.
The treble control provides adjustment of plus or minus 10dB at 15kHz.
These controls can be useful with difficult recordings, small loudspeakers, unusual room positioning or listeners requiring a modest tonal adjustment.
Source Direct
Source Direct bypasses the tone-control circuitry for a simpler signal path.
This provides a straightforward way to compare the direct amplifier path with the bass and treble controls engaged.
The preferred setting will depend on the recording, system and room rather than one mode being universally correct.
Linear Volume-Control Circuit
The MODEL 70 uses a linear volume-control arrangement designed to provide smooth adjustment and consistent channel behaviour.
The motorised control can be operated from the front panel or supplied remote handset.
Begin with a low volume whenever changing sources or connecting equipment, particularly when source components have substantially different output levels.
Stereo Pre-Amplifier Output
A variable stereo RCA pre-amplifier output follows the MODEL 70's source selection and volume control.
It can be used with a suitable external power amplifier, active loudspeakers or another compatible component requiring a controlled line-level signal.
The internal speaker amplifier can therefore remain part of the system while additional amplification is introduced where appropriate.
No Main Power-Amplifier Input
The MODEL 70 provides a pre-amplifier output but no direct main input.
Its internal power-amplifier section cannot be accessed independently while completely bypassing the MODEL 70 pre-amplifier.
Dedicated Subwoofer Output
A separate RCA subwoofer output simplifies the connection of a compatible active subwoofer.
Adding a subwoofer can extend low-frequency performance and reduce the pressure placed on smaller loudspeakers when the subwoofer is set up carefully.
The crossover frequency, phase and level are adjusted using the controls provided by the connected subwoofer.
Subwoofer placement and room interaction will have a considerable effect on the final result, so setup should not be based on output level alone.
Low-Noise OLED Display
A compact OLED display shows the selected source and operating information.
The display is designed for low electrical noise and follows Marantz's current industrial design.
Its restrained presentation avoids the large menu systems associated with network streamers and AV receivers.
Supplied System Remote Control
The supplied RC006PMCD remote controls volume, input selection, mute, tone functions and other everyday amplifier operations.
It can also control compatible Marantz CD players, including the matching CD 70.
Marantz system-control connections are provided for integration with compatible source components.
Automatic Standby
An automatic power-off function can place the MODEL 70 into standby after an extended period without operation.
Standby consumption is specified at 0.3W.
The function can help reduce unnecessary electricity use when the system is left unattended.
