Open up a new world of exciting audio content with the NA-11S1 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.

Listen to Computer, Web-based and Portable Digital Media
Equipped with an RJ-45 LAN port, you can connect the NA-11S1 to your home network to access thousands of internet radio stations and music streaming via Pandora, SiriusXM and Spotify. There's a front panel USB type A port that lets you connect your portable device directly, and it features automatic iPod detection and charging, even during standby mode. The USB type B port on the rear panel lets you connect a PC directly, and our newly developed Ground/Signal isolator technology helps to reduce PC noise for the highest quality sound.
Via AirPlay and your wireless home network, you can stream content from your iTunes library directly to the NA-11S1, and you can also access your iTunes content with the direct PC connection.

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.
Multiple Filters Offer Versatile Listening Options
The latest Marantz DSP processor (DSP PEC777f3) provides precision digital filtering, and the NA-11S1 offers a number of DSP modes that let you tailor the sound to your liking. There are two for digital sources, as well as the option of noise shaping and a DC filter with a 1.7 Hz cutoff.

Exclusive Output Technology Ensures Faithful Playback
For optimum audio fidelity, the NA-11S1 features high current, high resolution audiophile D/A converters, 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 analog 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.

Multiple Ports for Versatile Connectivity
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 analog volume control.

Rugged, Durable Construction
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 aluminum 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 analog and digital stages.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
