Marantz Model 50 Integrated Amplifier

Description

About the Marantz Model 50 Integrated Amplifier

The Marantz Model 50 Integrated Amplifier also includes Marantz HDAM-SA3 / HDAM-SA2 circuitry, a toroidal power transformer, MM phono input, six analogue inputs, stereo preamp output, subwoofer output, Power Amp Direct input, Speaker A/B outputs, tone controls, Source Direct, and a headphone output.

The MODEL 50 is ideal for listeners who already have, or want to choose, their own streamer, DAC, CD player, or turntable. It is especially well matched with the Marantz CD 50n, which adds network streaming, CD playback, DAC functionality, and HDMI ARC while keeping the amplifier itself purely analogue.

What We Think

At Rapallo, the Marantz MODEL 50 is a great choice for customers who want a proper hi-fi amplifier without extra digital features getting in the way.

The appeal is focus. This is not a streaming amplifier. It is not an AV receiver. Instead, it is a clean analogue integrated amplifier with good power, a solid MM phono stage, and the classic Marantz sense of warmth and refinement.

The 70W per channel output is enough for many quality bookshelf and floorstanding speakers. Plus, the 100W into 4 ohms rating gives it useful headroom with speakers that need a little more drive. Therefore, it suits real lounge systems as well as dedicated listening rooms.

We also like the system flexibility. The MODEL 50 includes stereo preamp outputs, a subwoofer output, and Power Amp Direct input. As a result, it can be used in a simple music system, a 2.1 setup, or even as part of a stereo / AV hybrid system.

For NZ customers building a premium but straightforward two-channel system, the MODEL 50 is a strong match with a good turntable, a streamer or CD player, and speakers from ELAC, Triangle, Paradigm, SVS, Focal, or Klipsch Heritage.

The Marantz Model 50 Is Ideal For

• Two-channel stereo hi-fi systems
• Vinyl listeners using MM cartridges
• Customers wanting a pure analogue integrated amplifier
• Systems with an external DAC, CD player, or streamer
• Listeners who do not need built-in HDMI or streaming
• Bookshelf and floorstanding speaker systems
• Customers wanting Marantz sound in a clean, focused amplifier

What the Experts Say

• AVForums gave the Marantz 50 Series a 9/10 review score. It called the MODEL 50 “the real star” of the pairing and said that, if digital inputs are not required, it could be the integrated amplifier to beat under two grand.
• SoundStage! Access reviewed the MODEL 50 and praised its build, analogue focus, low-level performance, dynamic punch, tonal balance, and ability to deliver music without getting in the way. The review also highlighted its MM phono input, pre-outs, subwoofer output, Power Amp Direct input, Speaker A/B outputs, and headphone output.
• HiFi and Music Source reviewed the MODEL 50 with the CD 50n and described the MODEL 50 as a pure analogue integrated amplifier with 70W per channel, six analogue inputs, MM phono input, preamp output, headphone output, and remote control. The review also found it easy to set up and enjoyable in use.

Frequently Asked Questions

1. What is the Marantz MODEL 50?

   Yes, the MODEL 50 includes a subwoofer output. This is useful if you want deeper bass with bookshelf speakers or a 2.1 stereo system.
8. Can I use the MODEL 50 as a power amplifier?
   Yes, it includes Power Amp Direct input. This lets the MODEL 50 operate as a power amplifier in a suitable system.
9. How is the MODEL 50 different from the MODEL 60n?
   The MODEL 50 is a pure analogue amplifier with no streaming or HDMI. The MODEL 60n adds HEOS streaming, HDMI ARC, digital inputs, and network features.
10. Who is the Marantz MODEL 50 best suited to?
    It is best for listeners who want a premium analogue stereo amplifier for turntables, CD players, streamers with analogue output, DACs, and passive speakers, without paying for built-in digital features.

Key Features

70W Per Channel Class A/B Power

The MODEL 50 delivers 70W per channel into 8 ohms and 100W per channel into 4 ohms. This gives it enough power for a wide range of suitable passive speakers.

Pure Analogue Design

There are no digital inputs, no HDMI, no Bluetooth, and no network streaming built into the MODEL 50. Therefore, it is ideal for customers who want a traditional analogue amplifier and prefer to choose their own external digital sources.

Marantz HDAM Circuitry

The amplifier uses Marantz HDAM technology, including HDAM-SA3 and HDAM-SA2 versions listed in the official specification. These discrete amplifier modules are part of Marantz’s signature sound approach.

Current Feedback Topology

Current Feedback topology helps the MODEL 50 deliver fast, controlled sound with good timing and stability. It is part of the amplifier’s core Marantz design.

Built-In MM Phono Stage

The MODEL 50 includes a moving magnet phono input. This allows you to connect many turntables directly, without needing a separate phono preamp straight away.

Six Analogue Inputs

The amplifier includes six analogue audio inputs, including the MM phono input. This makes it suitable for turntables, CD players, DACs, streamers, tuners, tape decks, and other line-level sources.

Stereo Preamp and Subwoofer Output

Stereo preamp output adds useful system flexibility. You can connect a subwoofer, add external amplification, or use the amplifier as part of a more advanced setup.

Power Amp Direct Input

Power Amp Direct input lets the MODEL 50 operate as a power amplifier in a suitable setup. This is useful for stereo / AV system integration or future preamp upgrades.

Speaker A/B Outputs

Speaker A/B outputs allow connection of two speaker pairs, or flexible speaker switching depending on the system. The amplifier uses Marantz SPKT-1+ speaker terminals.

Source Direct and Tone Controls

Source Direct mode gives a cleaner signal path for critical listening. However, bass, treble, and balance controls are also included when you want simple adjustment for room, speaker, or recording balance.

Headphone Output

A headphone output is included for private listening. The MODEL 50’s headphone output could drive Audeze LCD-2 headphones with headroom to spare during testing.

Premium Marantz Styling

The MODEL 50 uses Marantz’s modern premium design language, including a metal front panel, low-noise OLED display, symmetrical layout, and black or silver-gold finish options.

Suggested System Pairing

• Speakers: ELAC, Triangle, Paradigm, SVS Prime, Focal Aria Evo X, Focal Theva, or Klipsch Heritage models
• Turntable: Pro-Ject Debut Carbon EVO, Pro-Ject X1, Pro-Ject T2 Super Phono in phono-out mode, or another MM turntable
• Digital Source: Marantz CD 50n, standalone DAC, streamer, or CD player
• Cables: Black Rhodium RCA interconnects and Black Rhodium XTRA, Foxtrot S, Quickstep, Calypso, or Operetta speaker cable
• Upgrade Path: Add a powered subwoofer, external phono stage, better streamer, or separate power amplifier
