Marantz PM-11S1 Integrated Amplifier

The Marantz PM-11S1 is a high-end integrated amplifier that occupies a revered position in Marantz's Reference Series—a line engineered to achieve ultimate performance for discerning audiophiles. With an output of 100 watts per channel into 8 ohms and a staggering 200 watts into 4 ohms, this amplifier provides immense power reserves while maintaining finesse and subtlety in musical delivery. It features a fully balanced design from input to output, reducing noise and crosstalk and maximizing signal integrity.

At the heart of the PM-11S1 is a massive toroidal transformer and oversized power supply capacitors, giving the unit its excellent dynamics, bass control, and low-end authority. The amplifier also includes Marantz's proprietary HDAM-SA modules—ultra-fast, discrete amplification circuits that outperform traditional op-amps in speed and accuracy. These modules allow the PM-11S1 to deliver breathtaking resolution, revealing microdetails and spatial cues even in complex recordings.

This amplifier features a high-quality phono stage for MM cartridges, a precision volume control, and meticulously isolated internal circuits. Its copper-plated dual-layer chassis reduces vibration and electromagnetic interference, while its 15 mm thick aluminum front panel and control knobs add to the unit's luxurious and enduring feel. The PM-11S1 is also equipped with both unbalanced and balanced XLR inputs, offering ultimate flexibility for premium sources.

Sonically, it is known for a rich, organic presentation, with fluid midrange textures, extended highs, and fast yet controlled bass. It’s equally adept at driving efficient bookshelf speakers and more demanding floorstanders. The PM-11S1 is often described as musical rather than clinical, making it a favorite for long, immersive listening sessions.

Brand Fact: Marantz’s Reference Series, including the PM-11S1, is hand-assembled in Japan by master technicians. Every unit is built to exacting standards, embodying the company's founding philosophy: “Because music matters.”** Marantz’s Reference Series components, including the PM-11S1, are hand-assembled in Japan and represent the pinnacle of the brand’s analog engineering expertise.
