Understatement of the year: Marantz isn’t new to stereo amplification or hi-res audio streaming. The new PM7000N does, however, arrive as the brand’s first fully discrete integrated amplifier capable of hi-res music streaming.
The just-add-speakers streaming system utilises Marantz and Denon’s HEOS hi-res, multi-room platform, which opens doors to networked servers, Spotify, Amazon Music (including HD), Tidal, Deezer and internet radio. File supports goes right up to 24-bit/192kHz PCM and DSD5.6, and there’s AirPlay 2, Spotify Connect and Bluetooth onboard to boot.
Hi-fi components can be connected to the PM7000N too courtesy of four analogue (including one phono), two optical, coaxial and USB inputs. All of the digital inputs can automatically wake the PM7000N when sensing an audio signal, and the TV remote control can be programmed to directly operate the master volume control, mute, power on/off and source selection of the PM7000N.Outputs, meanwhile, span single analogue and subwoofer connection, the latter of which features an adjustable low-pass crossover.
Marantz loyals won’t be surprised to read that the company’s proprietary amp tech inside. It uses Current Feedback amplification and Hyper-Dynamic Amplifier Modules (HDAM-SA3), and features a toroidal transformer and instantaneous-current power supply that supplies 60 watts or 80 watts per channel of power into 8 ohms and 4 ohms respectively. The PM7000N also boasts a newly developed preamplifier section with an electronic volume control that promises “exceptional” signal-to-noise ratio.
Marantz has also worked to maintain signal accuracy and reduce interference by isolating the digital circuit within a shielded case. Pure Mode, too, disables the USB, wi-fi and Bluetooth elements to turn the PM7000N into a pure analogue amplifier.
To simplify the signal path, a new integrated phono design sees the integration of a FET (field-effect transistor) in the input stage, providing high impedance and thus eliminating the need for AC coupling capacitors.
The Marantz PM7000N (£999/$999) will be available from 15th November – but should you buy it? The answer is, in short, yes, which our exclusive review makes clear.
