Introduction

Your Expectations of Sound Quality...

providing a signal clear, and true to its source. The A.B.C. will output true, 24-bit audio les and supports a
variety of sample rates: 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, and 192kHz.

Digital processes may represent a sound exactly. Just as a professional taster might select the exact vintage after
careful inspection, so the computer will read, and re-read a disc as many times as it needs to, to ensure it has the
“exact” sound. This process is more accurate than a CD player may achieve: the player will read through only
once. It does not have the benet, as the taster does, to go back and resample.

The A.B.C. is nely designed to t effortlessly within your digital system. Your digital system will function
together as parts of an instrument. Your A.B.C. is built to match to your system, becoming a “bridge” between
your computer and your DAC.

Setting Up Your Digital Music
Collection

What are the Goals of a Digital Music Collection?

A wine may be perfected over generations; the equipment an audiophile employs should be as nely tuned. A
well-built interface, such as possessed by the A.B.C., does not interfere with the rened quality of the audio, yet
passes it along faithfully to its destination.

Care is given to the preservation of wine, from the angle it is stored at to the proper temperature of the room.
When dening goals for a digital audio collection, so too must the audiophile pay attention to such details.
When storing music, the music should be transferred from analog to digital in a precise manner. And just as the
wine connoisseur has a carefully crafted storage, so should the digital audio system’s hard disks be well-kept
and operated.

The music should be reproduced faithfully to its source, and stored in a safe, secure manner for years to come.
Because so much depends on the quality of the le, in addition to the quality of the equipment, part of the goal
should be to “do it right the rst time.”

How do I Rip Archival Quality?

When ripping to an archival collection, your motto should be, “Do it right the rst time.” As this is a relatively
new technology for many, this manual will seek to cover its basics, and to direct you to places where you may
nd additional resources.

When ripping, there are a number of important considerations. These are:

Consideration Why It’s Important

What le format should
I use?

Is my ripping software
up to the job?

Do I have a secure
place to store the les
when I am done?

Do I have enough space
to store the les?

Different le formats have different benets. We will get into these in
a moment.

A computer is able to read a disc multiple times when ripping. Ripping
software with good error-checking can check yet more often, and
potentially recover music from partially damaged discs. In addition,
some ripping software only rip at a lower rate, or only into certain
formats.

By secure we mean, will it last, and is it protected against such things
as hard drive failure?

Audio les can be quite large, so ensure you have plenty of space.

What File Format Should I Use?

Ripping at rst may seem as though it is a simple thing. That is, most computers will rip a disc with a fair
amount of ease. The concerns of an audiophile, however, are different than the average computer user.
Audiophile seeks to preserve and appreciate a higher-quality sound. The goal when ripping and storing the
music then, should be approached with care and art.

Stahl~Tek A.B.C. Page 7

The audiophile will choose le formats and software best suited to this goal.

When choosing a le format, many audiophiles go with AIFF, WAV, or FLAC for long-term storage. The below
table summarizes some benets of each.

In addition to a “working copy,” Stahl~Tek recommends having an “archival copy.” That is, a master set of les
preserved carefully in the highest quality digital format. All working copies then, will be made from this digital
master, which is to be set aside and preserved.

File
Format

AIFF

WAV

FLAC

Some Benets Some Potential Issues

Subtle differences introduced into the
AIFF works well with Macintosh computers,
devices, and iTunes. It is a non-compressed
and lossless format.

WAV has been with Windows for years and is
well-supported throughout a number of devices
aside from Windows, although it will not
always work on Apple products. It is typically
(though not always) non-compressed.

FLAC is an open source audio format. It stores
metadata very well, and can be converted
easily into WAV or AIFF without altering the
original data. It is also more standardized than
the other two formats.

format over time can cause a risk of

loss of metadata (that is, information

such as title tracks, album names, and

so forth).

Subtle differences introduced into the

format over time can cause a risk of

loss of metadata (that is, information

such as title tracks, album names, and

so forth).

While supported on many devices,

it is less prevalent than AIFF or

WAV. In addition, it uses lossless

compression, which may be a turnoff

for some users.

Is My Ripping Software Up to the Job?

When you begin to rip, there are a number of software packages available to you. Some of them have a better
interface, others offer more features. As you explore the digital side of audio, you will try different software and
develop favorites, preferences. Here are a few you might begin your journey with.

Operating System Ripping Software Why We Like It

Mac Max Good overall features, easy to use
Mac iTunes Nice integration over a number of devices

PC dBpoweramp Strong features, easy to use

PC

Jriver Media
Center

Do I have a secure place to store the les when I am done?

Because preservation of one’s collection must be approached as an art, storage must be approached similarly.
When preparing your collection, you will want at least two copies, an Archival (or “master” copy), and a
Working copy. The Archival copy will be invaluable should an experimental edit go awry, or should you wish to
convert to a different format for use on different devises.

Other guides suggest as many as three, though two should be considered the minimum.

Many guides will also point you towards the use of RAID systems. RAID stands for Redundant Array of
Stahl~Tek A.B.C. Page 8

Nice interface, works across a multitude
of devices; runs on your PC with
“controller” software for a Mac portable
device, such as an iPad

Independent Disks. What this means is, when data is written to one disk, it is simultaneously written to other
disks as well. If one drive fails, you still have your data.

RAID systems should be combined with automated backups for data security. They should not be considered
the same as a backup.

Do I have enough space to store the les?

Audio les, especially high quality ones, can be large. The higher the quality, the larger the le. File type and
codec play a role as well. A lossless compression format such as FLAC will result in a smaller size than WAV
or AIFF. A lossy compression format such as MP3 takes up the least amount of space, though obviously, an
audiophile is not ripping to MP3. Obviously, longer albums will require more space.

Troubleshooting

My DAC shows the same output no matter the sample rate (for example, 44.1kHz is displayed as
192kHz).

Your software may be upgrading (or downgrading) your source. For example, Windows Media Player will
downgrade any source over 96 kHz. Another program, such as JRiver, may be set to upgrade a source that is
below a certain sample rate. Software does through use of DSP, or Digital Signal Processing. You will need to
refer to your software’s documentation.

How can I tell what my output frequency is in Windows?

The Stahl~Tek custom A.B.C. driver comes with tools to measure your output frequency. To use these tools, do
the following:

1. Click on the small button to the left of the clock.



2. Click on the red “T.”

3. Select Device. Under Device is “Clock Source.”
Your current output frequency is listed here.



When connecting to my Mac via USB, once I connect my DAC or another audio device, the Stahl~Tek
A.B.C. dissapears or fails to appear.

This is an issue resulting from Mac’s USB specications. To resovle the issue, plug the A.B.C. into a different
port on your Mac.

Glossary

Audio Card: Audio Cards provide a digital to analog interface between the computer and stereo. Alternatives to
audio cards exist, such as USB or S/PDIF outputs, though this was not always the case. High-end audio cards,
such as the well-known Lynx, can offer benets to audio performance, while use of a USB DAC bypasses the
need for an audio card entirely. A USB DAC is a DAC which accepts a signal from a computer’s USB output.

Audio Codec: A codec is an algorithm used to COmpress or DECompress audio data. There are two types of
codecs: Lossless and Lossy. In Lossless compression, data is not lost, while in Lossy, it is. Different codecs
use different methods and formulas; therefore, quality can vary depending on the codec. A popular example of
Lossless compression is FLAC. Popular examples of Lossy include MP3, or OGG Vorbis.

Music Server: Music servers manage the retrieval, organization, and playback of a music collection. They
typically come in two formats: premade, and personal computers. Examples of premade systems include the
A.B.C., Sooloos, and Olive. These systems typically run an OS, such as Windows, Mac OS X, or Linux.

Network Attached Storage (NAS): NAS is an old concept that is gaining interest from audiophiles. In basic
terms, a NAS is a storage device that is connected to a computer network by means of an Ethernet cable. Once
connected to the network, the NAS may be viewed and accessed by any computer on that network, much like a
shared drive.

Network Attached Storage (NAS): A set of one or more hard drives that are accessed through a computer
network. NAS drives tend to possess larger storage capabilities than the average computer, and allow access of
les by more than one computer.

Metadata: Metadata describes the data in a le. Typically, in an audio le, it contains information about the
album, artist, or even cover art that the le contains. There are two types of metadata: associated metadata, and
embedded metadata.

Metadata, Associated: Associated metadata is stored separately from the le itself. This sort of metadata is
typical of more proprietary software, such as iTunes. Associated metadata does not travel with the le, itself.
That is, if the audio le is played by a different software, the metadata will not be seen.

Metadata, Embedded: Embedded metadata is stored inside the le, itself. The benet of embedded metadata is
that the metadata (such as artist information) stays with the le, no matter which device or software it is played
on. Files such as FLAC, AIFF, and ALAC support embedded metadata.

Ripping: Ripping refers to the process of copying music from a CD into a digital format.

Uncompressed Audio: Uncompressed audio is audio data that is not compressed. Popular uncompressed audio

formats are WAV and AIFF.
