The Model 50 is an integrated amplifier by Marantz that delivers 70 watts x 2 channels into 8 ohms and 100 watts x 2 channels into 4 ohms. It was released in 2024. It is a 2-channel design using a Class A/B output stage. 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 Marantz Model 50 has an MSRP of $1,800.

There are 10 Marantz amplifiers in our database. Below you can see the main specs of these amps.
Marantz 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 Marantz Model 50 is rated at 70 watts RMS into 8-ohms. Marantz provides this wattage at a THD (Total Harmonic Distortion) of 0.02% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 70 watts into 8-ohms (20 Hz-20 kHz) at 0.02%
- 100 watts into 4-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
- 113dB Signal to Noise Ratio

Which speakers suit the Marantz Model 50?
70 W into 8 ohms, 100 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?
Marantz Model 50 is rated at 70 watts into 8 ohms, which puts it in our 61 to 90 watts band. The next band up is 91 to 120 watts, which is worth about 1.5dB 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. Plenty of systems are better served by the Up to 60 watts band and better speakers.
When pairing the Marantz Model 50 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 Marantz Model 50 Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the Marantz Model 50 amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:
| Listening Environment |
Suitability |
| Near-field | Poor |
| Small Room | Average |
| Mid-size Room | Good |
| Large Room | Average |
| Very Large Room | Poor |
Inputs and Outputs
Besides the performance specs of the Marantz Model 50, the next important feature set that you have to evaluate is the input and output selections that it offers.
Marantz Model 50 has total of 5 Analog inputs including 1 Phono Input (MM).

Bluetooth Connectivity
Marantz Model 50 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 Marantz Model 50. 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
Marantz Model 50 features one Phono Input which is 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.
Subwoofer Output
Marantz Model 50 has a dedicated subwoofer output which can be used to connect it directly to a powered subwoofer via an LFE(Low Frequency Effects) cable.

Powered Subwoofers page to find a subwoofer that will work with Marantz Model 50 amp and your speakers.

Marantz Model 50 Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓70 watts per channel into 8 ohms, 100 into 4.
- ✓Signal-to-noise ratio of 113dB, so the amplifier itself should be inaudible between tracks.
- ✓5 analogue inputs, enough for a full rack of sources.
- ✓Phono stage built in (MM), so a turntable needs no separate preamplifier.
- ✓Pre-outs (Stereo RCA, Sub) leave room to add a power amplifier or an active subwoofer later.
- ✓A and B speaker terminals, for a second pair or for bi-wiring.
- ✓Headphone output (1/4).
- ✓Has tone controls.
- ✓5-year parts warranty, longer than most of the market.
- ✓Detachable mains lead (IEC 2-prong).
- ✗Analogue inputs only - a TV, computer or CD transport needs an external DAC.
- ✗The phono stage is moving-magnet only; a moving-coil cartridge would need a step-up or an external stage.
- ✗No Bluetooth and no network streaming - everything arrives over a cable.
