ABOUT THE DMS-700
The DMS-700 represent the 3rd generation of our Cary Audio’s renown DMS platform. This platform is the pinnacle of
network audio streaming playback and will provide years of trouble-free enjoyment. With a network connection, firmware
updates are pushed to the DMS and will notify you each time an update is available, ensuring all the latest features and
updates. The DMS-700 uses a single 4-channel AKM-4499 R2R Ladder DAC Chip. While the previous generation of DMS used
AKM’s outstanding voltage driven Delta-Sigma DACs, the DMS-700 use AKM’s flagship current driven R2R Ladder DAC.
Current driven R2R Ladder DACs are more difficult to implement but can sound more analog like allowing for more insight,
breath, and texture into your music. In addition, the DMS-700 uses an FPGA (Field Programable Gate Array) chip to work in
conjunction with the DAC to ensure absolute accuracy and precision timing. This timing is elevated even further in the DMS-
700 thanks to the use of premium Crystek Clock Oscillators, a decisive step forward from previous DMS generations. Of
course, playback of all current and future formats and resolutions including MQA, PCM up to 32 bit /768kHz and DSD up to
512 are natively supported with enhanced support for high resolution PCM and DSD audio via SPDIF inputs and outputs as
well. The DMS-700 is MQA certified with full MQA decoders with the latest MQA custom filters resulting in life-like studio
quality sound with a naturalness and decay that beyond reproach. The DMS-700 Network Audio Player/Streamer/DAC can
connect either wired or wireless to your network for playback of digital music files stored on networked computers, NAS
drives, or from internet music services such as TIDAL, Qobuz, Spotify Connect and vTuner. They are also Roon Ready
endpoints allowing for a content rich browsing and playback experience within the Roon ecosystem. Direct file playback can
also be achieved from the DMS-700 USB-A inputs using a USB Hard Drive/thumb drive, or SD Card inserted directly into the
front or rear of the DMS. For connecting to all other non-integrated music services, such as Pandora, Amazon Music, etc.,
the DMS-700 include high resolution better than CD Qualcomm aptX™ HD Bluetooth and Airplay streaming protocols. For
connecting legacy digital sources, the DMS-700 provides Coaxial, Optical, and AES/EBU digital inputs to round out a
complete digital music hub for all your digital needs. Headphone listening with the DMS-700 takes on a different twist with
the inclusions of Bluetooth output for connecting to Bluetooth headphones or speakers. The DMS-700 use advanced MU-
MIMO Wi-Fi technology for enhanced 5G Wi-Fi capabilities.

INSTALLATION
UNPACKING
This section describes the proper unpacking and installation procedures.
Unpacking
All Cary Audio shipping cartons have been specially designed to protect their contents and special care has been taken to
prevent damage under normal shipping conditions. Mishandling should be evident upon inspection of the shipping
container. If shipping damage is found after visual inspection, take care not to destroy the evidence. If necessary, document
the damage with photographs and contact the transport carrier immediately.
Carefully remove your new component from its packing carton and examine it closely for signs of shipping damage. We
strongly recommend saving all original packing cartons to protect your component from damage should you wish to store it
or ship it at a later date.
Power Requirements
The DMS-700 Digital to Analog Converter is designed to operate from AC main current. The design AC voltage is either
110V-120V or 220V-240V AC at 50-60 Hz.
In the Box
When unpacking your DMS-700, make sure the following accessories are included. You should find the following items
within the box:
•Power Cable
•Remote Handset
•Antennas (3)
WARRANTY CARD
IN THE USA: If you are the original purchaser of a new unit purchased from an authorized Cary Audio dealer, please go
online here https://www.caryaudio.com/warranty-registration/ to fill out a warranty registration within 15 days of your
purchase. Cary Audio also suggests that you keep your original packing cartons in case you ever need to ship the unit.
Warranty restrictions apply. Consult the warranty section at the end of this manual for details. Please be certain to keep a
copy of the original sales receipt from your direct purchase from Cary Audio or your authorized Cary Audio dealer to
validate the warranty if ever needed. The warranty is for the original purchaser only and does not transfer to any
subsequent owner.
OUTSIDE THE USA: Your local authorized Cary Audio distributor will make his own warranty policy for your country. Please
check with them for the terms of warranty for your new amplifier.
PLACEMENT
In general, the location of your new DMS-700 is not critical. Certain precautions must be taken to ensure optimum
performance. Avoid extremely hot locations such as near radiators or other heating units. Keep the top of the DMS-700
clear of books, paper or other equipment to protect against overheating.

12
ISOLATION FEET
The DMS-700 use a unique combination of isolation spikes and aluminum discs to reduce vibrations and resonance. This is
an integral part of the design and it is highly recommended that these be used. Doing so will improve the overall frequency
extension. Simply screw in the spikes to the underside of the permanently attached feet, then place the aluminum discs
under the spike so that the spikes sit inside the indents of the aluminum discs. This may require a little jostling of each
disk until each seems perfectly seated so that the entire chassis feels firmly planted and stable.

13
FEATURES
The following section describes the DMS-700 advanced features. Please read the Operation Section of this manual to learn
more on these unique features. The features are subject to change without notice or obligation.
USB & SD CARD NAS DRIVE
The DMS-700 has expanded the function of the 3 USB-A and SD Card Slot inputs to be accessible from a networked
computer. This means when the DMS is powered on, any storage connected to the DMS will act as a NAS Drive (Network
Attached Storage). This allows you to copy your music file directly onto the USB or SD Card from a network computer
without needing to disconnect them. This simply turns any USB drive or SD Card connected to the DMS into a NAS drive.
Playback from these drives can be direct (computer-less) or monitored and controlled from a computer-based server i.e.,
JRiver, Twonky, etc., or even via Roon. What’s more, if you have more than one DMS you can play files from one DMS to
another.
MQA CERTIFIED FULL DECODING TO 768 KHZ
MQA is a technology that captures the full magic of an original studio performance. Using pioneering scientific research into
how people hear, MQA delivers master quality audio in a file that is small enough to stream or download –the days of
sacrificing quality for convenience are over. Every nuance and subtlety of the artist’s performance – every tiny drop of
emotion is authentically reproduced. When you listen, you will be transported right into the very moment of creation. The
DMS-700 MQA decoder uses 16x rendering for 768 or 705.6 kHz playback. The DMS-700 uses the latest in optimization for
AKM DACs, making for an even greater musical experience.
APTX™ & APTX™ HD WITH CARY AUDIO’S FI™ BLUETOOTH IMPLEMENTATION
Bluetooth modules are a fantastic and convenient way in which to share and listen to music from online and mobile
sources. It’s not unusual for companies to use such modules as a complete end-to-end or add on solution whereby using
the cheap low-grade onboard DAC chips included in the modules and simply passing the analog signal of the module to the
analog output section. Our solution is to fully integrate (fi™) the digital information from the Qualcomm aptX™ HD
Bluetooth receiver, up to native 24 bit / 48kHz better than CD audio, into the entire digital circuit of the DMS-700. This
approach ensures that Bluetooth sources have the potential to sound like any other expensive input source whereby
utilizing our sophisticated digital topology of parallel DACs and our other integrated digital features such as; TruBit™
Upsampling, and OSO™ Reclocking. Now your Bluetooth sources can truly be high fi.
ADVANCED MU-MIMO WI-FI
The DMS-700 is now compatible with the latest MU-MIMO Wi-Fi routers, which means x2 faster data transfer in the 5 gHz
band while multiple devises are accessing data simultaneously. Additionally, MU-MIMO advantages only operated at the
5Ghz band. So, if you have a MU-MIMO capable router and the DMS-700 is within a reasonable distance, set the router to
5Ghz. If the DMS-700 is much further away or on different floors than the router, the 2.4 gHz band may be better since it
uses the SU-MIMO protocol. General rule of thumb is 5 gHz band is faster for short ranges between router and device
while 2.4 gHz is slower but has a greater range.

14
TRUBIT™ DSD & PCM UPSAMPLING & PCM TO DSD CONVERSION
Upsampling can be messy, leaving behind lots of digital artifacts resulting in noise and inaccurate signal generation. On the
surface, upsampling may seem like a good idea. But if not implemented properly it can be disastrous. Typically, upsampling
is done as a predefined one-size-fits-all approach, such as 96 kHz or 384 kHz. Utilizing a dedicated 128-bit DSP engine, Cary
Audio’s TruBit™ Upsampling allows for up to 10 different selectable sample rates and an increased bit depth of 32 bits. The
result is a signal free from digital artifacts that sounds accurate, pure, and a joy to listen to. What’s more, PCM sources can
be converted to DSD (DSD64, 128, or 256). Alternatively, a lower native DSD source can be Upsampled to a higher DSD
rate. PCM to DSD conversion and DSD upsampling takes our TruBit™ technology to whole new level of pure silky-smooth
analog like sound like never before from digital sources.
OSO™ RECLOCKING
This latest generation DMS takes clocking of the digital data to a new level. To achieve a new benchmark, the DMS-700
uses FPGA chips and Crystek Clock Oscillators to ensure the digital signal is transferred into Cary Audio’s digital ecosystem
with extreme care to ensure the best possible sound achievable. As a digital source transfers from point A to point B it
creates an insidious digital problem called ‘jitter’. To deal with this, Cary Audio developed something we call OSO™ Re-
clocking. This solution re-clocks all signals again once onboard as to ensure all jitter is virtually eliminated to a minute
degree. We call this OSO™, short for “Onboard Signal Origination” because this re-clocking and buffering creates a signal so
stable and jitter free it’s as if the origin of the signal was generated onboard and not from an external source.
THE OPERATION OF THE DMS-700 ASSUMES ALL USERS HAVE A MINIMUM OF A MODERATE LEVEL OF UNDERSTANDING
OF COMPUTERS, FILE SHARING PRINCIPLES, COMPUTER NETWORKS, AND OTHER ASSOCIATED PERIPHERALS SUCH AS:
ROUTERS, ETHERNET, WI-FI, USB HARD DISC AND FLASH DRIVES, SD CARDS, NAS DRIVES, COMPUTER OPERATING
SYSTEMS, THIRD PARTY SOFTWARE SUCH AS MEDIA/MUSIC SERVERS AND MEDIA PLAYERS, DIGITAL MUSIC
