Jaguar
couldn't be more excited about the new PS Audio DirectStream DAC. We
use the DirectStream as our digital reference and its designer, Ted
Smith, is a good friend who lives just down the road from the Jaguar
Listening Studio. We
love that this device converts PCM files to native DSD; this means the
user doesn't have to go out and replace all the music they've purchased
and ripped over the years. A standard Redbook CD is upsampled 10x and
output as a double DSD file...the result is sonic magic.

"The best way we've yet encountered to turn digital into music"

http://www.stereophile.com/content/ps-audio-perfectwave-directstream-da-processor

"But, for those who've waited for a computer-friendly DAC that offers, with every type of music file, the best musicality of which DSD is capable, the PerfectWave DirectStream may be in a class by itself."

"There
was an amazing sense of purity to the DirectStream's way with music as
if everything and anything extraneous had been stripped away."

"The DS is a game changer."

"PS Audio has perhaps achieved the impossible with the DS."

"The DS gets my highest recommendation; hats off and a bow to PS Audio."

Pure 100% single bit DSD based D to A Converter

Most
of today’s sophisticated DACs are IC based instruments using
off-the-shelf-chips that are Multi-bit Sigma Delta based designs. While
these are relatively simple to design and produce, they don’t often give
the best results sonically. Because they are one-chip systems
compromises are made in their architecture that found in DirectStream’s
custom based architecture. DirectStream takes both PCM and DSD,
upsamples the data and converts to single-bit DSD and then outputs pure
music regardless of input format for the data. The results of this
design can be heard in increased musical information presented to the
listener at every opportunity.

Purely passive output stage

Most
modern DACs use some form of active tube or solid state output stage to
amplify, filter and drive the DACs output. DirectStream takes a
different approach: passive. In one of the simplest, elegant and
musically correct executions of an output stage, high speed class A
video amplifiers are used as the final switch for the single-bit, double
DSD output of DirectStream; feeding a high performance passive audio
output transformer. The transformer is specially designed to act as both
the galvanic isolation between the DAC and the outside world as well as
the primary low pass filter required to present a perfect, low
distortion, low noise output signal. When you listen to DirectStream you
never are accosted by added bright, hard glare in the music as happens
with many active designs. Instead, clean, pure music flows from the
DirectStream directly to your preamplifier or power amplifier.

Resolution perfect volume and balance controls

Designer
Smith perfected a 100% bit-perfect volume and balance control that’s
built into DirectStream, enabling users to control the output level when
feeding directly into a power amplifier or preamplifier. That the
volume control is completely bit-perfect means there is no loss of
resolution for any volume setting, a feature unique amongst the majority
of DACS in the world today. The ability to eliminate the preamplifier
in the system without any resolution loss is a major benefit to
DirectStream’s outstanding musical performance.

Simple, direct signal path with only one master clock

Typical
high-end DAC designs use more than one master clock as you can see in
the drawing we provided in the Overview page. There are often separate
clocks for USB, Audio and others, causing major headaches for system
designers trying to synchronize the clocks. DirectStream obviates the
problem by basing the entire design on one master clock of extraordinary
high quality. Used is a low phase noise, low jitter clock designed for
DirectStream by Crystek. Using this advanced approach the need for
synchronization is eliminated, jitter levels are reduced and music is
delivered with a clarity rarely heard.

Immunity to jitter from sources

Sources
have always had a major impact on sound quality with DACS. Transports,
computers, CD players, cables all make a significant impact on
performance into a typical DAC. This problem has been significantly
reduced with DirectStream. Now, for perhaps the first time, sources of
just about any quality and jitter level sound nearly identical. For
example, you can take a cheap $30 DVD or CD player’s digital output,
connect with DirectStream and have sound quality unthinkable for such a
poor source. Performance levels no longer are dependent on the quality
of source or connections; certainly not to the degree they have been in
the past. Yes, cables and sources still make a difference, but with
DirectStream that difference is reduced to nearly background noise.
Whatever you use to play or stream your music now sounds as good as it
gets.

Asynchronous high speed USB

DirectStream
can match up to either a computer or a home network. If a network
connection is desired, there’s is the optional Network Bridge available
that slides right into the rear panel of DirectStream and adds an
additional input. You can also connect directly to your computer via
USB. USB communication, if handled properly, can have every sound
quality advantage of a dedicated CD transport or Network Bridge.
DirectStream provides a fully synchronous 24 bit 192kHz path for USB
based audio. Using a good quality USB cable between DirectStream and
your computer, like a quiet MAC Mini, provides an instant media server
that can be controlled through any number of handheld devices like an
iPod, iPhone or Android using a 3d party controller program. Your music
can be managed by iTunes, Bit Perfect, Pure Music or Ammara for ease of
use.

Polarity inversion

A
handy feature on DirectStream is the polarity (phase) control. This
touch screen option (available on the remote as well) allows users to
select normal or inverted phase for every input and for every
performance. Sources and music have no standard for absolute polarity, a
fact easily demonstrated by switching polarities on the as the music
plays. Many Audiophiles mark their discs in phase and out of phase and
are very careful to select the proper phase before playing each disc.
Some CD players and sources themselves invert phase so that a disc you
believe is inverted actually is correct played on a specific device and
incorrect on yet another. To fix this problem you can assign each input
on DirectStream to switch to the proper polarity when you activate that
input. Touching this control is the same thing as reversing the
loudspeaker connections of both loudspeakers (+ to -) at either the
amplifier or speakers. All live acoustic music is in absolute phase but
some recordings may accidentally be made inverted and should sound more
realistic and pleasant when you correct their phase with the switch.

Play directly into your power amplifier or preamplifier

DirectStream
offers the ability to play directly into either your preamplifier or
power amplifier through either its balanced or single ended outputs. You
can select the optimum gain setting through DirectStream’s setup menu
to match your amplifier and loudspeaker’s sensitivity. If you choose to
go through a preamplifier, it’s easy to set DirectStream at maximum
level (or any level you wish) to match the preamp’s gain. But should you
choose to eliminate the extra electronics of the preamplifier,
DirectStream is more than capable of driving the power amplifier
directly. DirectStream’s unique zero-loss volume control maintains full
resolution bit-perfect performance at any volume setting from the lowest
to the highest levels.

Hear more than you ever imagined from CDs

DirectStream
converts everything to DSD, even PCM before delivering the music to
your system. This approach, coupled with careful design, low jitter and a
simple and direct signal path has the benefit of uncovering details
buried in the music you may not have realized are even there. CDs come
alive with subtle details that were never apparent with your older DAC;
details you never knew even existed. CDs sound more like high resolution
audio than you ever imagined, closing the gap between higher resolution
PCM and DSD copies. No longer do you need to consider replacing your
current CD library because once you hear what’s truly on your discs, you
may not need to consider upgrading to a higher resolution copy at all.
Yes, it is that obvious and significant.
