Enquire about this product

Network players have been on a roll for some time now, and there’s no doubt that the future of audio is intertwined with high quality digital files. It follows that there needs to be something which is the equivalent of the high-end disc player to ensure that high resolution music is played back in the best form possible. Marantz have risen to the challenge, as you’d expect from this company with their record of superb player dating back to the early days of CD, and flowing onwards to SACD/CD players of note.

The NA11 S1 is such a player.   In their words it is a “reference-class Network Audio Player and DAC, which includes a host of internet streaming and device connectivity options. Equipped with exclusive Marantz technologies, including the use of multiple HDAM (Hyper Dynamic Amplifier Module) devices, the NA-11S1 includes connectivity to a range of portable devices and it also includes PC connectivity, all easily controlled with the supplied remote as well as with your iOS or Android smartphone, thanks to the available Marantz Remote App.”

“A host of Marantz digital technologies combine to deliver the ultimate audio experience. The NA-11S1 is equipped with dual master audio clock generators with jitter reduction for numerous sampling frequencies and bit depths, up to 192 kHz/24 bits. A number of audio file types are supported, including WAV, WMA, MP3, MPEG-4 AAC, FLAC and ALAC, as well as DSD over PCM.”

Connections: LAN port, USB, and Airplay can all be used.  The DACs are “high resolution audiophile quality, operating in differential mode for the lowest noise and widest dynamic range. The critical post-D/A current-to-voltage conversion is handled by the latest Marantz HDAM-SA2 devices, which feature precision discrete components in lieu of standard op amp chips. The final analogue output stage features additional HDAM devices, and there are two output choices – unbalanced (RCA) and balanced (XLR). The balanced outputs also feature a phase-inversion option for compatibility with any XLR-equipped pre-amp.”

“Dual (optical and coaxial) outputs are provided for connection to other components, and there are also dual digital inputs that let you use the NA-11S1 as a DAC with other digital audio sources. There’s also a high-quality dedicated headphone amplifier, which features its own output stage that’s also equipped with HDAM-SA2 devices along with a precision variable analogue volume control.”


“As befits its reference-class status, the NA-11S1 features a rugged chassis with internal copper-plated surfaces. The thick 5mm top panel can easily support the weight of an additional component, and the dual-layer bottom plate and die-cast aluminium cabinet feet provide solid rigidity along with additional resistance from external vibrations. The beefy power supply features a high current toroidal power transformer with multiple oxygen free copper (OFC) secondary windings, and is housed in a copper-plated enclosure for maximum shielding. Multiple separate circuit boards ensure minimal interference between the various analogue and digital stages.”
