The PM-14S1 integrated amplifier delivers superb sound quality and operational versatility, and features exclusive Marantz technologies
such as our HDAM (Hyper Dynamic Amplifier Module) discrete circuitry and current feedback topology. Featuring a massive power supply
with a high current toroidal power transformer wound with Oxygen Free Copper secondaries that is rated at 650 VA along with high speed
high current Schottky Barrier Diodes in the rectifer circuit, the PM-14S1 is rated at 90 watts per channel into 8 ohms and 140 watts per
channel into 4 ohms (both from 20Hz - 20kHz). A total of 24 HDAM units are employed throughout the amplifier, including the line level
stage, phono equalizer stage and the power amplifier stages. The power amplifiers feature separated circuitry and dual massive heat sinks
along with multiple discrete high current power transistors to deliver wide dynamic range and stability even with lower impedance speaker
loads. The elegant remote control can also control the matching SA-14S1 Super Audio CD/CD player, and there's a power amp direct input
that allows the PM-14S1 to be used as a standalone power amplifier for even more system configuration versatility.
