Fully Analog, Designed for Current and Future Needs: 70Wpc Marantz Model 50 Integrated Amplifier Features HDAM SA-3 Circuitry, MM Phonostage, Six Inputs, Much More

Purity and simplicity merge in the form of the fully analog Marantz Model 50 integrated amplifier. Its intentional exclusion of digital speaks to the audiophile in everyone and prevents unnecessary complexity that could degrade the signal. And by using two parallel output transistors per channel instead of the typical one, Model 50 supplies higher levels of current to your speakers than most units in this class. The real-world result: Dynamic, natural, immediate sound that reveals previously hidden details, completes notes, and resolves challenging passages. 

Outputting a convincing 70Wpc, Model 50 is loaded with fully discrete HDAM SA-3 circuitry, a Marantz Musical Phono EQ MM phono preamplifier, tone controls, and six analog inputs. Plan on expanding your system? Use the subwoofer and preamplifier outputs. Want to listen while everyone else is sleeping? Tap into a headphone amplifier complete with HDAM SA-2 circuitry. Model 50 even goes overboard with an E-Vol volume control, which adjusts both the circuit gain and output voltage. Translation: High precision, extended range, and low distortion. 

As a bonus, the textured front panel and porthole display ensure Model 50 looks great doing its job. Ditto the aluminum control surface and sculpted texture of the front panel. A five-year manufacturer warranty and our satisfaction guarantee give you further assurance that your setup — whether small or large — will be in good hands with Model 50.

Current Feedback Amplification 
Current feedback amplification is a well-known, Marantz-original circuit technology, thoughtfully designed to match the requirements of high-res music for wide-bandwidth, high-speed reproduction. Marantz current feedback amplifiers reduce the need for phase compensation by minimizing negative feedback. This simplifies the signal path and results in  excellent transient response and superb sonic transparency across the full bandwidth. Unlike conventional voltage feedback topology, current feedback also makes the power amplifier capable of driving difficult loudspeaker loads, meaning Model 50 is ideal for a very wide range of loudspeakers. 

HDAM Technology 
While many brands claim unique engineering in sensitive and analog circuits, most use commonly available integrated op-amps in critical signal paths. Those op-amps can compromise audio integrity and limit design ingenuity. Marantz developed an entirely unique replacement for integrated circuits using ultra-high-quality discrete components. Marantz HDAM circuitry outperforms traditional op-amps both in the listening room and the laboratory. Very high-speed signal handling dramatically improves bandwidth. Clever amplification design minimizes distortion and ideal layout silences noise. 

Precision E-Vol Volume Control 
Model 50 uses an ultra-precise electronic volume control system that adjusts both the circuit gain and the output voltage. This system maintains high dynamic range and limits noise across a far broader volume range than traditional systems. More traditional integrated amplifiers use basic potentiometers which can suffer from poor channel balance and increasing noise and distortion over time.
