About the PM-14S1

The PM-14S1 is a high-end integrated amplifier from Marantz's Reference Series, designed for audiophiles seeking exceptional sound quality and operational versatility. It delivers 90 watts per channel into 8 ohms and 140 watts per channel into 4 ohms with a total harmonic distortion of 0.05%, ensuring wide dynamic range and stability even with low impedance speakers. The amplifier employs Marantz's proprietary HDAM-SA3 discrete modules and current feedback technology for fast, accurate signal handling. It features a massive 650 VA toroidal power transformer with oxygen-free copper windings and high-speed Schottky Barrier Diodes for a robust power supply. The PM-14S1 includes a Constant Current Feedback MM/MC phono equalizer, multiple analog inputs including phono, and a power amp direct input for flexible system integration. It has a low noise LCD display, solid copper speaker terminals, and a linear volume control for precise sound adjustment. The amplifier supports a frequency response from 5 Hz to 100 kHz ±3 dB and a signal-to-noise ratio of 106 dB on line inputs. It also includes a dedicated headphone output with HDAM discrete modules for high fidelity headphone listening. The chassis is designed for rigidity and anti-vibration with a double-layer bottom plate and aluminum extrusion heat sinks. The unit measures approximately 17.3" W x 4.9" H x 18.7" D and weighs about 40.8 lbs. It comes with a remote control that can also operate the matching SA-14S1 CD player. The PM-14S1 is no longer in current production but remains highly regarded for its musicality, build quality, and audiophile-grade performance.
