From PS Audio:

"In 2009, the
high-end audio world was shaken with the introduction of the world’s first high
resolution memory player, the PerfectWave Transport. Nearly eight years later
PS Audio engineering has taken another giant leap forward with the introduction
of the PWT’s replacement, the DirectStream Memory Player, the last transport
you’ll ever need.

DMP is a universal
transport, capable of playing multiple types of optical discs including,
DVD-Audio, AVCHD, SACD, HRx, CD, CD-R/RW, DVD±R/RW, DVD±R DL, BD-R/RE, as well
as stored data through its USB digital input.

CD performance of
DMP has been enhanced to a degree once thought unobtainable, narrowing the gap
between Red Book CD reproduction and high resolution PCM and DSD. Played
through DMP, ordinary CDs take on new life, with improved dimensionality,
soundstage width and depth, improved dynamics (both micro and macro), increased
low level harmonic information, and richer tonal balance.

Plus,
hear SACD for the first time

The protected DSD
layer of SACD has long been available only through D/A converters built in to
players and a few receivers and surround processors. These internal D/A
processors, while adequate, were never capable of playing back stored music at
the quality and performance levels enjoyed by mastering engineers. Now, with
the introduction of PS Audio’s revolutionary new memory player, DMP, owners of
our DirectStream series of DACs can uncover all that they have been missing.
Based on a proprietary handshake protocol between DMP and PS Audio DACs, through
our advanced I²S interface, pure DSD is streamed to, and processed in, the same
reference quality DAC used by mastering engineers.

At the heart of DMP
is an advanced version of core PS Audio technology, the Digital Lens. Invented
in 1993 by PS Audio founder Paul McGowan and chief engineer, Bob Stadtherr, the
Digital Lens focuses digital data into a perfect stream, unaffected by the
transport’s mechanical and electrical properties.

In digital audio,
timing is everything. Jitter, noise, and a lack of isolation have major impacts
on sound quality, especially affecting lower resolution media such as CD.
 DMP’s advanced Digital Lens technology solves timing, noise and isolation
problems through a unique combination of buffer memory and FPGA based digital
processing.

Up until DMP’s
advanced Lens technology was introduced, the internal Digital Lens found in the
older PerfectWave Transport, relied on an intelligent RAM buffer to
isolate digital data from the mechanical optical drive and laser mechanism.
Separated from the CD reading device, data accumulated in the Len’s buffer
until output through a fixed low jitter clock to the DAC.

After eight years of
research and two years of development, PS engineering has been able to shorten
the memory requirements and improve the timing of digital audio data. The new
Lens takes advantage of advances in semiconductor architecture, found in FPGAs
(Field Programmable Gate Array). Using a single large scale integrated
FPGA, PS chief DMP architect, Bob Stadtherr, devised a segmented
structure including intelligent RAM, two-way isolated communication with
the drive, and near-field output latches controlled by an ultra-low jitter
fixed clock. The results are extraordinary.

DMP’s advanced
Digital Lens and low-jitter fixed clock perfectly focuses the isolated
datastream to the I²S, coax, or AES/EBU outputs directly to your DAC. The
results of this fine, perfectly timed data stream must be heard to fully
appreciate its full implications.

New life to Red Book
CD

The Compact Disc was
first introduced in 1982, nearly 35 years ago, as of this writing. Over the
years, steady progress has been made improving its musicality. But retrieving
all that is possible from this optical medium has remained somewhat elusive
until the introduction of the DMP.

Most engineers
in our field, including our own, failed to recognize the critical
need for timing perfection to appreciate all that is available on CD. Not until
2009, with the introduction of the PerfectWave Transport, did we begin to
understand that there was more to CD than we had ever imagined.  The PWT
demonstrated that careful extraction of data, coupled with isolation of the
output clock, yielded unexpected benefits: more information than we knew
existed.

Our next uncovering
of what treasures lay hidden in the CD was even bigger. DirectStream DAC.
DirectStream DAC’s inventor, Ted Smith, opened our eyes to what was possible to
render (playback) from the original optical storage method—once believed to be
so lacking that only higher resolution upgrades could salvage the sound.

The PWT opened our
eyes to what could be
extracted, the DirectStream DAC turned the lights on for what could be
rendered, and the DMP has finally opened wide the door to what is possible
when extraction and timing are near-perfect.

Cover
art and song titles

DMP enjoys a new
user interface that includes song titles and tracks that can be read from a
distance. Like its predecessor, the PWT, album art can be automatically
downloaded when DMP is connected to the internet.

Every time you play
a disc (and are connected to the internet) a copy of the cover art and song
titles are kept for you on your own private library page, accessed through our
website. From your personal page it is a simple matter to correct any of the
CD’s information, change cover art and polish your CD collection.

SACD extraction

Sony and Philips
corporations introduced the CD’s successor, the SACD (Super Audio Compact Disc)
in 1999, 17 years after the original launch. Instead of downsampled PCM from
higher resolution original recordings, which many Red Book CDs are based upon,
SACD held the promise of access to the original master tape or recording
through a new format, PDM (Pulse Density Modulation) that Sony and Philips
rebranded as DSD (Direct Stream Digital).

Because this new high-resolution
digital format was essentially identical to the master tape, strict copyright
protections were put in place to protect the rights of artists and recording
labels. Those protections remain in place today, as well they should. Most
collections of SACD have only been heard through Sony/Philips authorized DACs,
internal to the players, unavailable as a separate digital audio datastream to
external DACs.

PS Audio’s DMP is
one of the first transports to provide external access to the pure DSD
layer on SACD. DMP can do this, legally, because the raw data stream cannot be
copied. DMP owners with PS Audio’s DirectStream DAC, or DirectStream
Junior, can access this encrypted layer through our unique I²S interface.
Once connected, DMP authenticates the presence of a PS Audio authorized DAC
and, for the first time, listeners can get closer to master tapes than ever
thought possible.

DirectStream DACs
are pure DSD based and nothing sounds quite as magical as DSD copies of master
tapes processed into exquisite analog through DirectStream DACs.



I2S through HDMI output

There are
three ways to get digital audio data out of the DMP: S/PDIF, AES/EBU or
I2S HDMI. I2S is the preferred method if you have a PS Audio DAC or any
manufacturer’s DAC that can receive it. Three such I²S interface are
provided, allowing for 6-channel high resolution audio to be streamed from DMP.

S/PDIF (and AES/EBU)
are the standard delivery methods found on all transports and, while excellent,
remain a compromised format.

Standard digital
outputs take three separate internal clocks along with the raw music data and
combine them into one stream to the DAC. This mashup of music and clocks causes
the audio to sound flat and harsh compared to I2S.

A much better way of
delivering the music is what I2S does, by transferring the clocks and data on
separate wires within the HDMI cable, and the audible results are impressive.
Simply use any HDMI cable between the DMP and appropriate DAC and you
are transferring data perfectly, through I2S.

A growing number of
DACS and devices are adopting the PS Audio HDMI standard for digital audio
transmission because of its superior audio quality.

Powerful
analog discrete power supply

Clean and
well-regulated power is essential for a high-performance universal disc player
like the DirectStream Transport. Instead of the typical switch mode power
supply, a fully analog approach is taken with DMP.

Three separate and
isolated analog power sections make up DMP’s power supply. Fed from a large
toroidal power transformer with three galvanically isolated windings, each of
the three power stages utilizes discrete full wave rectification based on
high-speed low-loss diodes. Energy storage for the three sections comes from a
bank of low ESR high-value capacitors bypassed by non-inductive film
capacitors.

Each of the three
power storage banks are then double regulated by discrete, linear, voltage
regulators which reduce ripple to the microvolt level and lower impedance to
well below an Ohm.

Playback
of stored data

The front panel USB
input on DMP is available for small music collections stored on USB drives.
Plug in a USB thumb drive and its contents can be accessed and played back
through DMP. While the instrument itself is capable of handling large numbers
of tracks, selection can become cumbersome if there are too many.

Tracks from the data
drive are displayed in small groups on DMP’s touch screen, and navigating
larger libraries can be time consuming. PS engineering added this input as a
courtesy port offering quick access to a friend’s favorite album or track. We
imagine being at a consumer audio show and customers wishing to hear music
stored on their thumb drives will find this input convenient and excellent
sounding.

Many high-end audio
music lovers still have large CD collections as well as small to
medium sized SACD and high resolution PCM (like HRx) libraries. Few of us are
eager to unload the hundreds, often thousands, of discs we’ve collected over
the years. But we know there’s far more to be gotten off those discs than most
of us now enjoy.

The DirectStream
Memory Player changes all that, disrupting the status quo, changing what’s
possible in the digital audio landscape.

Owning the DMP is an
investment, one that will pay off in a rich musical experience for years to
come.

DMP offers the
chance to hear what you’ve been missing on your discs, whether Red Book CD,
CDR’s from downloads, HRx, or the master DSD layer on SACD. You’ve invested
much in accumulating your music library. Now, it’s time to really hear what’s
been locked inside for so long.

DMP is the finest
transport mechanism we know how to build.

We trust you’ll
enjoy the new DirectStream Memory Player as much as we do.

Perhaps the last
great transport ever made

The chassis of the
DMP is a metal sculpture of aluminum and steel, weighing in at 20
pounds of elegance and beauty. The top cover is a hand painted, hand polished
piano black cover that has been lavished over for hours.

The DirectStream
Memory Player has been a work of passion; a quest for perfection in musical
excellence. The instrument is assembled, programmed and tested at our
production facility in Boulder Colorado by skilled craftspeople. There is a
measure of pride of workmanship that goes into every one of these products and
it shows from the moment you open the unit up and plug it in.

PS Audio has been
building products of passion, elegance and engineering excellence for more than
40 years. Family owned and cared for, PS Audio believes in our products and our
customers. Those are not just empty marketing terms so often bandied about in
brochures and websites.
