ABOUT THE DMS-800PV
When we created the DMS-700, we began thinking about a no holds barred version of the DMS capable of
competing with the best of the best in Network Audio Players/Streamers/DACs. First, it would have to exceed
the performance of the DMS-700, which is no small feat. After considerable research and design, the DMS-800
Professional Version (PV) was born.
The DMS-800 Professional Version (PV) is a limited-edition marvel. Simply put, the DMS-800PV is the ultimate
expression of our famous DMS platform. If the DMS-700 is analog-like, the DMS-800PV IS analog. Bigger, deeper,
wider, and smoother in sound, the DMS-800PV is capable of revealing the actual instruments within the
recordings and not just the sound of the instruments. This allows for a more dimensional insight into the music,
illuminating a more true-to-life sound. Inside, the DMS-800PV is a dual mono design, doubling almost everything
inside the renowned DMS-700. While the DMS-700 utilizes a single digital/analog stage board with a single
current output switched resistor 4 channel AK4499EQ DAC (equivalent to 4 DACs), the DMS-800PV uses separate
right and left channel digital/analog stage boards. Each stage board has its own 4-channel current output
switched resistor AK4499EQ DAC for a total of 8 individual DAC channels for a true, fully balanced dual
differential circuit. In addition, the DMS-800PV includes a Crystek Oscillator Clock, two separate DSP driver
stages, 14 groups of independently regulated power supplies, and two independent groups of analog stage
regulation power supplies as well as other enhancements. The DMS-800PV has a larger 5” high-resolution
display and a slightly taller stance than previous DMS models. Inside the DMS-800PV is a marvel of circuitry
design regarding power regulation and both digital and analog circuitry.
The DMS-800PV is also Roon Ready and MQA Certified. Like other DMS products, the DMS-800PV allows
streaming from on-board TIDAL, TIDAL Connect, Qobuz, Spotify Connect, vTuner, or from files stored on a
network computer or NAS Drive. If that wasn’t enough, it includes three (3) USB-A ports for listening from
connected USB hard drives, flash drives, and even from an SD card. As an extra measure for convenience, the
DMS-800PV also includes aptX™HD input and output (output for Bluetooth speakers or headphones) as well as
Airplay.
Additional features include Ethernet or Wi-Fi connectivity, TruBit™7-step Selectable PCM upsampling to
768kHz, and selectable PCM to DSD conversion with selectable 3-step DSD upsampling. Digital inputs include
Coaxial (x2), Optical (x1), and AES/EBU (x1) as well as Coaxial and Optical digital outputs, RCA and XLR fully
balanced outputs, OSO™Re-clocking, MU-MIMO Wi-Fi, and a full 3-volt output and variable volume control for
direct-to-amplifier connection.

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-800PV 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-800PV, 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-800PV 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-800PV
clear of books, paper, or other equipment to protect against overheating.
11

ISOLATION FEET
The DMS-800PV uses 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.
12

FEATURES
The following section describes the DMS-800PV's advanced features. Please read the Operation Section of this manual to
learn more about these unique features. The features are subject to change without notice or obligation.
USB AND SD CARD NAS DRIVE
The DMS-800PV has expanded the function of the 3 USB-A and SD Card Slot inputs to be accessible from a networked
computer. This means that 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-800PV MQA decoder uses 16x rendering for 768 or 705.6 kHz playback. The DMS-800PV uses the latest in
optimization for AKM DACs, making for an even greater musical experience.
APTX™AND 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 is 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-800PV. 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-800PV is now compatible with the latest MU-MIMO Wi-Fi routers, which means x2 faster data transfer in the 5
GHz band while multiple devices are accessing data simultaneously. Additionally, MU-MIMO advantages only operated at
the 5Ghz band. So, if you have an MU-MIMO capable router and the DMS-800PV is within a reasonable distance, set the
router to 5 GHz. If the DMS-800PV 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. A general rule of thumb is 5 gHz band is faster for short ranges between the
router and device, while 2.4 GHz is slower but has a greater range.
13

TRUBIT™DSD AND PCM UPSAMPLING AND 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 take our TruBit™technology to a whole new level of pure silky-smooth analog-
like sound like never from a digital source.
OSO™RECLOCKING
This latest generation DMS takes the clocking of digital data to a new level. To achieve a new benchmark, the DMS-800PV
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 is 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 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 is as if the origin of the signal was generated onboard and not from an external source.
