Marantz announces Model 30 integrated & SACD 30n player

  • Marantz has today announced two new mid-to-high-tier products that are apparently the first to adopt the storied manufacturer’s new ‘design language’.

    The first unit is a fresh take on the Model 30 integrated amplifier that Marantz first introduced in 1970.

    The 2020 Model 30 is an all-analogue design whose two stages – pre-amplifier and power amplifier – enjoy separate power supplies. An oversized toroidal transformer, shielded from the rest of the board in a ‘double steel case’, and neighbouring linear power supply circuit juice the pre-amplifier stage whilst a separate power supply promises high current delivery to its neighbouring and (according to Marantz) load-independent switch-mode (Class D) power amplifier. The upshot is a power output that doubles as impedance halves: 100wpc into 8 Ohms, 200wpc into 4 Ohms and 0.07% THD with both channels driven / continuous power.

    From the press release: “This ensures maximum control over any connected speakers to follow even the hardest bass attacks and provides clean power for the reproduction of the finest details.”

    At the time of writing, no power output ratings were provided by Marantz.

    Also inside the Model 30 sits a MM and MC phono pre-amplifier that’s 1) DC-coupled throughout, 2) built from Marantz’s HDAM technology – that ensures only discrete components are used – and 3) deploys JFETs to ensure a suitably high input impedance. MC input can be set to 33 Ohms, 100 Ohms and 390 Ohms using the hardware selector on the front panel.

    Back to the press release: “The exclusion of coupling capacitors further simplifies the design, reducing signal distortion and enhancing signal purity.”

    The Model 30 integrated will begin shipping in early September in a choice of silver or black for €3000/£2700.

    The second new unit is the SACD 30n that plays SACDs and CDs via Marantz’s (proprietary) SACDM-3L transport mechanism and upconverts all incoming PCM content to Quad DSD (11.2MHz) using the (also proprietary) Marantz Musical Mastering (MMM) technology which has been divided into two separate MMM-Stream and MMM-Conversion stages.

    From Marantz’s white paper on MMM: “The MMM-Stream section of the process replaces the oversampling filters normally used in digital to analogue conversion, and allows the implementation of the Marantz Musical Mastering filtering. These filters – one providing a slow roll-off and very short impulse response, the other offering the option of a medium roll-off with short pre-ringing and longer post-ringing – are essentially the same as those found already in the reference class Marantz SA-11 disc player and NA-11 network music player, but here they’re implemented at a much higher oversampling rate, thanks to that upconversion to DSD11.2.”

    Instead of a traditional DAC chip, the Quad DSD signal is converted into an analogue signal via an ‘MMM-Conversion’ stage and then that analogue signal is fed into the unit’s HDAM output stage.

    Marantz reports that two system clocks ensure the most accurate up-conversion of any incoming PCM signals, whether they’re from a disc, rear-panel digital inputs or the in-built HEOS network streamer, which supports Amazon Music HD and Tidal (but not Qobuz) and (presumably) puts the ‘n’ in the model name.

    Rounding out the SACD 30n’s feature set is a variable gain (low, mid and high) dedicated headphone amplifier that is built using Marantz’s HDAM-SA2 circuitry.

    The SACD 30n will also begin shipping in early September in a choice of silver of black for (€3000/£2700).
