Network stereo amplifier: Marantz PM7000 N Silver Gold

Network stereo amplifier: Marantz PM7000 N Silver Gold

The Marantz PM7000N combines the functions of a complete streaming streamer with a high-end analog integrated amplifier. The device uses the topology of circuits with current feedback and proprietary discrete amplifier modules of the third generation HDAM SA3. This design minimizes noise, increases slew rate, increases dynamic range and greatly extends the frequency range, delivering superior sound quality from conventional stereo recordings to Hi-Res audio formats. As a result, according to the manufacturer, a more dynamic, accurate and detailed sound is provided. The carefully designed Marantz PM7000N high-current power supply contains a shielded toroidal transformer and a pair of high-capacity capacitors (each 15,000 microfarads). This provides a power of 60 watts at a load of 8 ohms. The circuits of the model are equipped with high-quality audiophile components, and radiators made of aluminum are used for cooling.

With support for the HEOS wireless multi-functional ecosystem, the amplifier opens up great possibilities in terms of accessing streaming services such as Spotify (Free or Premium), Amazon Music HD, Deezer, Tidal, etc. This unit can be integrated into a wireless multi-room installation built on the basis of HEOS devices. To control the Marantz PM7000N , a remote control and an application are provided. You can also command the "integrator" through the voice assistants Google Assistant, Amazon Alexa, or Apple Siri.

The front panel of the amplifier is decorated with a three-line OLED display. Supports Apple AirPlay 2, dual-band Wi-Fi and Bluetooth. Audio libraries stored on PC, Mac or NAS servers are accessed via WLAN or LAN port. ALAC, FLAC, WAV up to 24-bit/192 kHz and DSD up to 5.6 MHz are supported over a local area network and using the USB port built into the rear panel of the case. There is an MM phono stage on board, the input section of which uses FETs. In switching, a switchable shielded block of digital inputs should be allocated. It is possible to connect an active subwoofer, and two pairs of branded Marantz SPKT-1 + screw terminals are used to connect speakers.
