Features
The world’s first* mono D/A converter that
realizes the full potential of the Super
Audio CD format
(* as of August, 2004)
Our approach of “improvement in sound quality through
discrete L/R channel transmissions” has evolved into a
completely discrete L/R system having two D-01s, one
handling the left channel, and the other the right channel.
The left and right audio signal paths have nothing at all for
common use, both paths are completely isolated and
identical, creating the highest possible reproduction quality,
non-compromised sound. This system also proves its ability in
reproducing ambience and presence data and recreates
details of the performance environment or a feeling of the
original recording session.
What’s more, because each channel has its own power
supply, the design of this supply can be optimized with ample
headroom, achieving an ideal D/A conversion.
• 2 XLR (ES-LINK), 1 RCA, and 2 IEEE 1394 inputs are provided
• DSD signals from Super Audio CD are fed in through XLR
terminals in an Esoteric-exclusive format, ES-LINK, or through
the IEEE 1394 interface.
• A maximum 192 kHz PCM signal can accepted (both Dual
and Stereo transfers available).
• When stereo or multi-channel signals are fed in, only the
sound of the channel you set as explained in the section,
“Channel Selection”(pages 11 and 13), is selected.
• Three digital filter options are provided: FIR, RDOT, and
FIR+RDOT. The filtered signal is converted up to a maximum
768 kHz and then sent to the multi-bit D-A converter
PCM1704. The DSD signal from Super Audio CD is converted
to 88.2 kHz or 176.4 kHz PCM data before being sent to the
digital filter.
• Equipped with RAM-Link (Refined Asynchronous Memory
Link), using a high-precision crystal oscillator, that when
entering word sync mode, the RAM-Link is automatically
activated and acts to eliminate jitter caused before the first
stage of the DAC.
• For the D/A converter, a combination of as many as eight
PCM1704 multi-bit D-A converters is used for the best
possible S-N ratio and linearity, which makes it possible to
faithfully replicate the ambience and presence of the
performance environment.
• The driver circuitry that sends out D/A converted signals uses
a discrete circuit structure operating on ±42 volt rails with
emphasis on driving force and slew rate, making a significant
contribution to the remarkable sound.
Word Sync enabled - Making Synchronizing
with External Equipment Possible
The word sync feature operates either in “OUT” mode (as a
word clock generator) or in the “IN” mode that allows this
unit to lock to an external word clock. It can lock to 44.1,
88.2, 176.4, 48, 96, 192, 100, 48P, 96P, 192P and 100P
(kHz) inputs/outputs. (“P” represents “4% down mode for
PAL films”.)
Selecting the “Rb IN” mode will select a PLL circuit devoted
solely to synchronizing with a rubidium or other highprecision clock. The use of ESOTERIC’s rubidium master clock
generator G-0s, will produce the most remarkable listening
experience with a feeling of speed and subtle clarity.
Analog potentiometer allows a direct
connection to a power amplifier
With the built-in analog potentiometer (“VOLUME”),
concern’s over truncating or dropping bits, as used in digital
attenuators, is negated.
Copper wires of 6N purity are used for
primary internal wirings, further enhancing
sound quality
High purity 6N copper wires are used for the supplied AC
power cord and most of the internal wirings that may have
effect on the sound quality, thereby boosting the purity and
resolution for a crisp, textured sound.
For the insulating sheath, polyorefin, non-PVC material, is
used out of environmental considerations as well as sound
quality. PVC is not used for any wiring inside the unit. The
high purity 6N copper cable is developed with the help of
Acro Japan Ltd. as is the case with the Esoteric “MEXCEL”
interconnection cable and high purity 8N copper cable.
Highly rigid chassis is immune to internal
and external vibrations that might degrade
sound quality
Thick aluminum is used on the top, side, bottom panels and
rounded corners in addition to the front panel. The entire
body is supported by Esoteric-exclusive pinpoint feet (patent
pending) made of case-hardened tool steel. Exacting
attention is given to the highly precise mounting of all
mechanical parts, the rigidity of the housing, and the
elimination of sympathetic vibrations. To make double sure,
an 8-mm thick plate is used for the upper cover that is subject
to the sound pressure and vibrations from the speakers.
The front and side panels, constructed of thick brushed
aluminum, and the rounded four corners create a feeling of
dignity and gravitas, fitting only to the top level mono D/A
converter for Super Audio CD/CD.

i.LINK (IEEE 1394)
The i.LINK format, also known as IEEE 1394, is an international
specification for the transferring of extremely fast data.
This unit is ready for i.LINK (AUDIO).
By connecting an i.LINK (AUDIO)-capable device to the IEEE 1394
(or i.LINK AUDIO) terminal on this unit using an i.LINK cable, you
can transmit Super Audio CD multi-channel signals that could
not be transmitted except in analog format in the past. With
i.LINK AUDIO, Super Audio CD can be transmitted in its original
digital format, in addition to the capability of transmitting 2-ch
linear PCM data and multi-channel compressed audio signals.
If you have multiple i.LINK-capable devices, you can connect
them through other devices to transmit data between them.
With i.LINK, you don’t need to be concerned about the order of
connection and wiring errors and phase issues are virtually
eliminated.
Copyright protection system DTCP
To play back audio sounds recorded on Super Audio CD or DVD
discs using i.LINK, both the player and the D/A converter need to
be ready for the copyright protection system DTCP (Digital
Transmission Content Protection). The D-01 already accepts
DTCP.
Data transfer rate
There are three transfer rates: 100 Mbps (S100), 200 Mbps
(S200), and 400 Mbps (S400). This unit is capable of transferring
data at a maximum 400Mbps.
For connection to an i.LINK-capable device, use a commercially
available S400-compliant 6-pin i.LINK cable.
When connecting multiple i.LINK-capable devices, avoid
connecting a device having slow transfer rate between devices
having high transfer rate since this reduces the transfer rate of
your whole system. Connect devices having high transfer rate
towards the source as far upstream as possible.
NOTES
<
Among the i.LINK formats there are “MPEG-2 TS” for BS
digital source and “DV” for digital video for DVD recorders,
as well as the “i.LINK (AUDIO)” (A&M Protocol). Never
connect devices that are not ready for i.LINK (AUDIO) to this
unit. If you do, this unit and others may get out of order or be
damaged.
<
In the process of data transfer, avoid plugging or unplugging
the i.LINK cables while in use or switch the power on and off.
< Among the i.LINK-capable devices there are some that, if not
turned on, are not capable of relaying data.
< There is a possibility some i.LINK-capable devices will not
respond to this unit’s command.
How to connect multiple i.LINK-capable
devices
Daisy chain connection
You can daisy-chain up to 17 devices including this unit.
Connection in tree structure
If you are using a device having three or more i.LINK connectors,
you may want to get the connection branched out. This way of
connection allows you to connect up to 17 devices including this
unit.
Your system does not work if data is fed back to the output
device. Be careful not to create a loop.
