Marantz PM-17SA (1999)

An integrated amplifier that weighs 16 kilograms and delivers 60 watts per channel into 8 ohms. The numbers only hint at what the Super Audio circuitry is doing inside.

Overview

The Marantz PM-17SA came out in September 1999 at ¥110,000. SACD and DVD Audio were just starting to show up, and Marantz built this integrated amplifier to handle the wide bandwidth those formats would need. The "SA" in the name is not decoration. It means this pre-main amplifier inherits the Super Audio technology first introduced in the PM-14SA, adapted into the PM-17 chassis.

Rated output is 100W + 100W into 4 ohms, 80W + 80W into 6 ohms, and 60W + 60W into 8 ohms, both channels driven from 20 Hz to 20 kHz. That is healthy current delivery into difficult loads. The damping factor of 100 into 8 ohms (20 Hz to 10 kHz) suggests the amplifier keeps a firm grip on woofer behavior. Total harmonic distortion is rated at 0.01% at both-channel drive into an 8-ohm load, and intermodulation distortion (SMPTE) is the same 0.01%. Those numbers hold up even by modern standards.

The case is 458 mm wide, 110 mm tall and 429 mm deep, and it weighs 16.0 kg. That is a serious chunk of hardware. The body is highly rigid aluminum, not for looks but because Marantz engineers knew mechanical resonance finds its way into the signal path if given the chance. Power consumption is rated at 180W under Japan's Electrical Appliances and Materials Safety Law, on 100 VAC at 50/60 Hz.

Key Features

Absolute SA Technology

Marantz's own documentation says the PM-17SA uses "Absolute SA Technology to improve the sound quality." It is a specific engineering response to Super Audio formats. SACD and DVD Audio pushed frequency response requirements well past what CD demanded, and the PM-17SA's frequency response in Source Direct mode for CD inputs runs from 5 Hz to 70 kHz within +0/-1 dB. You would not see that on an amplifier designed a decade earlier. Output bandwidth is rated at 10 Hz to 50 kHz into an 8-ohm load at 0.04%. That reaches well into territory no human ear can detect, but which the ultrasonic noise from high-resolution formats can reach.

Current Feedback Topology and HDAM

Both the power amplifier and preamplifier sections use current feedback topology, which offers advantages in slew rate and phase linearity compared to conventional voltage feedback. The preamplifier uses Marantz's unique voltage amplification module, the "Adjustable HDAM," with twin monaural construction. It is not a single board with two channels sharing resources. It is a dual-mono layout where each channel gets its own amplification path, which minimizes crosstalk and inter-channel interference. The basic configuration inherits almost all of the capabilities of the PM-17, which was already a well-regarded integrated amplifier in Marantz's lineup.

Power Supply Engineering

The power supply gets a super-ring core toroidal transformer, which reduces leakage flux compared to conventional EI-core transformers. The supply section also has a new low-power foil power block from Chemicon, plus high-quality resistors, film capacitors, and Schottky barrier diodes in each rectifier circuit. The power feed lines and GND bus bar were completely reconsidered to keep impedance low and suppress potential fluctuations.

Warm-Up Meter and Build Quality

The warm-up meter lets you check the heat-up state of the amplifier. That makes practical sense, since class AB amplifiers sound their best once they reach thermal stability. German-made WBT speaker terminals are fitted. An aluminum top system remote controller is included, and an inlet-type AC cable means you can swap the power cord.

Connectivity and Phono Stage

The input and output complement is generous for an integrated amplifier of this era. There are four line inputs, a tape system input/output, a phono input, a CD-R (MD) input/output pair, pre-out and main-in terminals, one speaker output, and a headphone output. The pre-out and main-in jumpers let you use the PM-17SA as a preamplifier driving a separate power amp, or as a power amplifier fed from an external preamp.

The built-in phono amplifier handles both MM and MC cartridges, with input sensitivity of 2.5 mV/47 kΩ for MM and 230 μV/100 Ω for MC. Maximum allowable input at 1 kHz is 150 mV for MM and 15 mV for MC, which leaves headroom for high-output cartridges. RIAA deviation is held to ±0.2 dB across 20 Hz to 20 kHz. Signal-to-noise ratios are rated at 90 dB for MM, 76 dB for MC, and 112 dB for high-level inputs (IHF A network, input shorted).

Source Direct and Tone Controls

A source direct switch bypasses the tone control circuitry entirely. When the tone controls are engaged, bass offers ±8 dB at 100 Hz and treble ±8 dB at 10 kHz. The Full Rec Selector lets you record from one source while listening to another, a feature that was getting less common as the 1990s wore on.

Historical Context

The PM-17SA uses the PM-17 as its base and applies the Super Audio technology introduced in the PM-14SA. The basic design inherits almost all of the capabilities of the PM-17, so Marantz was refining an existing platform for next-generation digital audio rather than starting from scratch. Service manuals were shared between the PM-17SA and the PM-17mkII, which suggests the models were developed in parallel.

The PM-17SA ver. 2 followed in 2002 at ¥120,000. It is a distinct product with its own specifications, not a running change to the original. The 1999 original and the 2002 ver. 2 are separate models with different specs in several key areas, so don't mix them up. Forum discussions occasionally compare the PM-17SA to the later PM-8003, with one Audiogon member arguing that "since the PM 17sa is built to a higher standard, why wouldn't it sound better?" Formal reviews of the PM-17SA itself remain scarce in the archive's sources.

Owner reports are mixed but generally positive. One stereo.ru forum member noted that the amplifier handles every genre well in a small room, though it won't play heavy music convincingly in a large space. The same owner defended the 17th against its detractors, suggesting it's "not as bad as people say." Another owner reported a humming sound developing in the right channel after a week of use, though this appears to be an isolated incident rather than a pattern of known failures. The service manual notes that variable resistors R627 and R727 (on PCBs P601 and P701 for left and right channels respectively) should be set fully counterclockwise, a detail that may matter when troubleshooting bias or DC offset issues.

Reverb sellers describe the sound as "clear, well-balanced," and one enthusiastic listing calls it "an exceptional amp at a great price." The PM-17SA was designed with the high-resolution SACD format in mind, and that shows in its extended bandwidth and low distortion figures.

The PM-17SA represents a transitional moment in Marantz's history — the company applying lessons learned from its Super Audio development to a mainstream integrated amplifier platform. It's not the most powerful amplifier Marantz ever built, nor the most expensive. But it is, in many ways, one of the most complete — a thoughtfully engineered integrated that balances power, flexibility, and build quality in a way that has kept it relevant to listeners decades after its release. If you find one in good condition, it's worth serious consideration.
