Marantz just announced the Reference Series PM-14S1 Integrated Stereo Amplifier, which replaces the PM-15S2, and offers the newest current feedback technology using Marantz’s unique HDAMs (hyper dynamic amplifier modules) to produce room-filling sound with exquisite nuances.
Featuring a massive power supply with a high current toroidal power transformer and high current Schottky Barrier Diodes in the rectifier circuit the PM-14S1 is rated at 90 watts per channel intro 8 ohms and 140 watts per channel into 4 ohms (both from 20 Hz-20kHz). A total of 24 HDAM units are employed throughout the amplifier including the line level stage, phono equalizer stage and 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 is power amp direct input that allows the PM-14S1 to be used as a standalone power amplifier for even more system configuration versatility.
Other audio advantages, high-quality sound enhancements, and useful functions include:
- Newly designed Marantz original high-quality, high-purity copper speaker terminals
- Rigid mechanical construction for anti-vibration
- Double-layered bottom plate and aluminum die-cast foot
- Toroidal transformer (650 VA)
- Low-noise LCD display
- Total sound balanced retuned with optimized parts
- Linear control volume with new volume-control integrated circuit (IC)
- Floating Control Bus System (FCBS) for bi-amp, multichannel configuration
- Power amp direct input
- Can be operated from an iPhone, iPod, or Android device using the Marantz Remote
- App in combination with the Marantz NA-11S1 network audio player (sold separately)
- Auto standby, low power consumption in standby mode (less than 0.2W)
Price and Availability
The Marantz PM-14S1 Integrated Amplifier will be available for $2,999.
