Features
sa8003/sa7003 cOmmON
Features
This unit can play back the outstanding sound
performance of Super Audio CDs. This unit has the
following major features.
• Low-noise low-distortion filter circuit and
high-speed HDAMSA2-type output amplifier
with the differential input type HDAM
• Playback of CD-R/CD-RW discs
• Playback of CD-R/CD-RW/CD-ROM discs
containing WMA and MP3 files
sa8003 Features
The SA8003 has been upgraded from SA7003 as in
the following.
• Toroidal transformer
The SA8003 features a toroidal transformer that
produces less vibration and magnetic leakage flux
compared to conventional power transformers.
The materials and manufacturing process of the
ring-shaped core are strictly controlled to reduce
vibration, while the short-ring attached to the
perimeter of the transformer reduce magnetic
leakage flux.
• Large-capacitance block capacitor
A large capacitance 3300 µF capacitor carefully
selected for its acoustic characteristics is
incorporated into the power supply circuit.
• Audiophile-grade film capacitors and
electrolytic capacitors
The SA8003 features the same audiophile-
grade film capacitors and electrolytic capacitors
specifically used in top-range models.
• Double-layered chassis
• High-grade machined analog audio output
connectors
• Playback of USB audio (MP3/WMA/WAV)/
iPod
This unit can play back MP3, WMA, WAV, and
AAC files by connecting an USB device or iPod to
its USB connector.
• Copper-plated chassis

1. Super Audio CD
The Super Audio standard is based on Direct Stream
Digital (DSD) technology. This new direct-stream
digital format comprises a 1-bit system that has a
digital sampling frequency that is 64 times higher
than that of conventional audio CD. The results are
spectacular: a frequency response of over 100k Hz
and a 120 dB dynamic range over the entire audible
spectrum. Mixed with as many of the original
frequencies as possible, the audio information
audible for human ears sounds much more natural.
All audible frequencies are, after all, embedded
in the frequency range as emitted by the sound
source. A better reproduction does not exist! For
the first time your ears will relive reality.
There are three types of Super Audio CDs.
• Single-layer Disc
• Dual-layer Disc
• Hybrid-layer Disc
Disc Types
Single-layer Disc
Dual-layer Disc Hybrid-layer Disc
HD layer HD layer CD layer HD layer
And each type may contain two areas of recorded
information.
• High quality stereo area
• High quality multi-channel area**
• Single Layer Disc
It can contain both high quality stereo area and
high quality multi-channel area** information.
• Dual Layer Disc
It can contain both high quality stereo area and
high quality multi-channel area** information.
And a double amount of information can be
stored on the disc thanks to the second layer.
• Hybrid Layer Disc
Not only does this disc contain both high sound
quality stereo area and high sound quality multi-
channel area** information, it also has a CD layer
in the second layer, so it can be played on a CD
player.
Hybrid Super Audio CD Disc
1 CD layer that plays on any of your
existing CD players
High-Density layer containing:
2 - High sound quality stereo
3 - High sound quality multi-channel**
The number of tracks recorded may vary per layer. It
will be shown on the display window of the unit.
**This unit is a stereo-only player, and so it
cannot play high-quality multi-channel audio
areas. (It does not recognize multi-channel
areas.)
2.
Audio CD (CDDA)
Audio CDs contain music tracks only.
3.
CD-R / CD-RW
This unit can play back the CD-RW (ReWritable)
discs as well as ordinary Audio CD and CD-R
(Recordable) discs.
• The CD-R and CD-RW discs should contain
properly-recorded TOC* information so that they
can be played back. In CD recorders, the task of
writing TOC information is referred to as finalizing
the disc. Discs that are not finalized cannot be
properly recognized as an Audio CD and played
back by regular CD players and Super Audio CD
players. For details, please read the instruction
manual provided with a CD recorder.
* TOC stands for Table Of Contents and contains
information such as the total number of tracks
and total playing time of the disc.
• As the playback of a CD-RW disc necessitates
partial change of the player setup, it may take
longer time for reading the TOC information than
when an Audio CD or CD-R disc is played.
