Introduction

As you know, in recent years the way to listen to music has

changed. There has been a progression from the use of physical

media to a more digital approach, allowing access to unlimited

digital entertainment content via the internet or from the library

stored on a computer. It can be iTunes, Windows Media Player or

streaming music or watching YouTube and many more. The com-

puter is a centre piece to all this entertainment.

The computer is just a simple player and in a standard setup the

performance is just average or even less.

But there is also a way to lift the experience to a complete new

level of enjoyment, making the computer a good player, by giving the

responsibility for the audio to an external component, for example a

“USB-DAC”. A DAC is a Digital to Analogue Converter and the USB

terminal is connected to the USB output of the computer.

Doing so we won’t be only able to enjoy the above mentioned

standard audio, but gain access to high resolution audio too,

exceeding the CD quality of 16-bit / 44.1kHz. It is possible to enjoy

studio master quality as 24-bit/192kHz recordings or even the

SACD format DSD with a bitstream at 2.8MHz and even 5.6MHz.

However to reach the above, some equipment is needed which

needs to be set up and adjusted. This document will guide you

through this journey to PC-Audio. It will provide you with the

information you need to get a good understanding for the topic.

As a reference product we will use the Marantz Reference Network

Audio Player NA-11S1 with USB-DAC.

MARANTZ GUIDE TO PC-AUDIO

MARANTZ GUIDE TO PC-AUDIO | NA-11S1 | 05.2013 | 2www.marantz.eu

The NA-11S1 has been designed to give you access to a wide

range of music from a variety of different sources such as:

• Internet Radio via your internet connection.

• all your music stored on a PC / Mac or NAS (network attached

storage) drive through to your home computer network.

• (stream) your music stored on an iDevice or in an iTunes library

by using AirPlay.

• ﬁ les stored on a Smartphone, USB stick or a Portable

Hard Drive via the front USB-A connection.

• ﬁ les stored on your computer by a direct connection of the

PC / Mac via the rear USB-B connection.

In this document we will mainly focus on the last option on the list,

the USB-B connectivity as this is the recommended way for music

lovers to enjoy their music in the best quality possible. The player

acts as a DAC – Digital to Analogue Converter (in fact it replaces

the soundcard of your PC / MAC) and directly converts the digital

music signal to analogue domain to hand it over to the ampliﬁ er.

But ﬁ rst let’s dig a bit more into the different ways of accessing

music to get a better understanding and clarify some terminology.

When you ﬁ nish the document you will have all the information you

need to get the best audio performance from your PC-Audio and,

speciﬁ cally, from the NA-11S1.

DIGITAL CONNECTIONS

LAN-Local Area Network

Let’s start off with the LAN connection and it possibilities. You most

probably are already familiar with it so we will just touch on it.

The LAN connection gives you access to the internet via the router

and to all the PC, Mac or NAS-Drives located in your network. You

can directly access more than 10,000 internet radio stations and

Podcasts, and stream music stored on your PC / Mac and also from a

NAS drive. All your downloaded or locally ripped music is accessible.

It is also important to know that there is some limitation to the ﬁ le

formats. It is most common that the following ﬁ les can be handled by

network players: MP3, WMA, WAV, AAC, FLAC and by better players

the high resolution ALAC, FLAC HD and also WAV ﬁ les.

In addition you will have direct access to internet streaming services

such as Spotify and last.fm, and you can use AirPlay to stream music

from an iDevice or iTunes. Android smartphones will use the DLNA

capability here.

Other digital inputs

As you will discover, there are two different USB ports on the

NA-11S1. The ﬁ rst of these (USB-A) is conveniently placed on the

front so you can plug in a USB key, a Smartphone or a portable

HDD. This is a synchronous connection and is the simplest method

of implementing USB audio from portable devices.

This is a USB-A port.

The Second USB-B port on the rear panels is for connecting a

PC or Mac directly, and supports not only PCM signals up to 192

kHz/24bits, but also DSD 2.8MHz and 5.6 MHz for maximised

versatility. This counts for the NA-11S1. Other USB-DAC’s might

not support all resolutions. Additionally, for the NA-11S1 a newly

developed Ground/Signal isolator technology helps to reduce PC

noise for the highest quality sound.

This is a USB-B port.

Using this connection will bypass your PC audio board (soundcard)

to directly access the high quality DAC of the external player. There

are other technologies to it, such as “asynchronous mode” and

“bit-transparent mode”, but this will be explained at a later stage

when we are going to explain how to use this connection and how

to get the best audio quality. Another big beneﬁ t of this PC to DAC

connection is that there is no ﬁ le limitation, as everything playing

on your PC / Mac media player will be reproduced by the NA-11S1,

as long as it is a stereo signal in PCM or DSD.

Just to complete the list of digital inputs we need to mention here

the optical and the coaxial digital connection. By these the NA-11S1

can be used as high end DAC as well for other devices with this

type of digital output, for example an Apple TV or other device, to

dramatically increase their audio performance. On the image below

you can see these inputs together with the USB-B input on the right.
