Marantz PM-14S1 Stereo amplifier


You might ask what makes the Marantz PM-14S1 Stereo amplifier such a musical and accomplished integrated amplifier? Rather than one or two unique features, it is the total design package of the PM14S1 that combine to create a stunning audiophile component which will astonish you with it's music making abilities.

First up is the larger toroidal mains transformer which is electromagnetically sealed from the environment by an aluminium screening cap - no mains radiation can escape to damage the audio signals passing through the amplifier. The transformer is also potted in resin to eliminate any winding buzzing, making the PM 14 S1 completely silent and free from background noise when under power.

The two Nichicon power supply reservoir capacitors have high capacity to deliver current pulses on musical peaks, and are hard wired to the circuitry for minimum resistance and therefore better grounding and lower hum and noise. Separate heatsinks are employed for left and right channel power amplifiers to maximise channel separation/ reduce crosstalk.

Volume control design has been carefully planned - the volume control passes a DC control signal to the volume control circuitry, thereby eliminating the need to bring the left and right channel pre-amplifier signals in close proximity - this in turn reduces crosstalk to offer the widest possible stereo sound stage.

The HDAM modules of the preamplifier sections are more advanced than in lower down models in the Marantz hierarchy - additional components are employed in a more complex and high performance configuration to offer even better musical performance. The power supplies feeding the HDAM modules have tight voltage regulation and high current reserves so that the preamp can respond to the full dynamic range of modern high definition recordings.

The mechanical design of the enclosure has be paid great attention by the designers - it's heavy chassis and three piece aluminium faceplate gives the PM14S1 massive structural rigidity, making the circuitry within virtually isolated from external vibration.
