The DSMP is probably the best Transport made, at any cost.

From the PS website:

Locked inside your CD, HRx, BluRay, and SACD collections is a wealth of music you’ve not yet heard. The DirectStream Memory Player uncovers the
musical treasures long-buried in your library. Eight years in research, two years in development, the DMP is our crowning achievement in musical
reproduction of optical media.
Breathe new life into your CD collection played through any DAC. Send the raw DSD layer of SACD into your DirectStream or
DirectStream Junior DAC so you can hear, for the first time, what’s long been unavailable to external DAC's in these high resolution discs.

35 years after the introduction of the CD, PS engineers have perfected the art of data extraction and delivery so you can finally hear what’s been locked away in your
CD and SACD collection. The DirectStream Memory Player (DMP) is a universal optical disc transport with a twist inside: an advanced Digital Lens. The Lens, first
invented in 1993 by PS Audio’s Paul McGowan and Bob Stadtherr, electrically isolates the mechanical transport/laser mechanism of optical disc
readers, improves audio quality to a degree few systems have yet achieved, and focuses audio data into a single, bit-perfect, timing-perfected stream to your DAC.

CD reproduction through DMP now comes closer than ever to high resolution PCM and DSD, uncovering new layers of dimensionality, soundstage, depth and musicality
previously unobtainable in other optical readers or server based audio systems.

DMP opens the long restricted DSD layer of SACD to PS Audio DAC's. Through a unique code-handshake, DMP will deliver the raw DSD layer of
copyright protected SACD directly into your PS Audio DAC. This means that for the first time you’ll uncover the wealth of audio’s finest
digital medium, DSD, and hear exactly what the mastering engineers who created these discs have enjoyed all along.
Welcome to DSMP, the last optical disc player you will ever need.

Stellar DAC/Preamp

Available in black or silver

There isn’t a DAC made that doesn’t benefit from a great analog preamplifier. The Stellar Gain Cell DAC combines the benefits of both—a full-featured DAC with an exceptional fully balanced analog preamplifier controlling its output level. Fully balanced circuitry from input to output, the Stellar Gain Cell DAC builds upon years of research and innovation in the art of digital audio and Class A analog amplification. Together, or separately, they create an extraordinarily rich, full-bodied musical experience few standalone products can match. Stellar Gain Cell DAC is the perfect foundation for those unwilling to compromise sound quality. Rich. Lush. Powerful. A music lover’s answer to spiraling cost-no-object equipment without sacrifice. It also has the connections to decode the new Direct Stream Music Player for SACD as well as redbook playback. When used with the S300 stereo amp or M700 mono amps it makes a formidable package with hi end performace and a hi value cost.

Stellar M700 mono amplifiers
340 watts @ 8 ohms / 700 watts @ 4 ohms
$2995.00 a pair


Available in black or silver

A pair of M700 mono amps placed on any loudspeaker brings forth the lush, rich and soul-satisfying power of two completely independent power blocks with headroom to spare. One listen to a hugely loud and complex musical passage effortlessly rendered by the M700 pair and you’ll know you made the right choice.

Rated at 340 Watts into 8Ω and 700 Watts into 4Ω, the the fully balanced M700 combines the best of two worlds: ultra linear, high-current, Class D technology for the output stage; a discrete, Class A MOSFET based Analog Cell for the all-important input stage. The M700’s rich, warm, and engaging sonic character comes from the Analog Cell. Its powerful, authoritative control over the loudspeaker stems from its high current, ultra-low impedance Class D output stage.

S300 Stereo power amplifier
140 watts/ch @ 8 ohms / 300 watts @ 4 ohms


Available in black or silver

The Stellar S300 fully balanced stereo power amplifier is a dual mono power amplifier capable of effortlessly driving demanding loudspeaker loads to concert levels. Rated at 140 Watts per channel into 8Ω and 300 Watts per channel into 4Ω, the S300 combines the best of two worlds: ultra linear, high-current, Class D technology for the output stage; a discrete, Class A MOSFET based Analog Cell for the all-important input stage. The S300’s rich, warm, and engaging sonic character comes from the Analog Cell. Its powerful, authoritative control over the loudspeaker stems from its high current, ultra-low impedance Class D output stage. When combined with the Stellar Preamp/DAC it makes a wonderful $3199.00 package.

Ted Smith learned much in the 7 years it took him to develop DirectStream. At first blush it seemed a relatively straightforward task to develop a lower cost version by taking costs out of low hanging fruit like the chassis, user interface, and PC boards. But the goals were loftier than that. The product directive asked for similar architecture to DirectStream in a PerfectWave-like chassis, with the network Bridge built in and performance not less than 85% of the original. A tall order by any measure.Retooling the chassis, replacing the touch screen with a less expensive OLED display and manual volume control was relatively straightforward work by PS Engineering. The real challenge fell upon Ted Smith's shoulders. How do you get 85% of an instrument's performance with 41% less to spend? The answer turns out to have a number; two years of hard work. The end result is DirectStream Junior.

Who was the DirectStream Junior built for?   Customers who want to uncover what's been missing in their libraries, but could not manage a DirectStream DAC. At $3,999, DirectStream Jr. (DSJ), with its built in Bridge II, is slightly more than half a similarly outfitted DirectStream (DS). That makes it a more cost effective DAC than even the original PWD.

No, it is not a DirectStream when it comes to ultimate performance, but DirectStream Junior offers 85% of DirectStream's performance at a significantly lower price.

Below is the summation of the 1st review of the new PS Audio Direct Stream Digital DAC. This DAC was Stereophile and The Absolute Sound Product of the Year

In the Stereotimes review they concluded with:

"After listening to the PS Audio PerfectWave DirectStream DAC for the past few months it is my opinion that DirectStream represents a new benchmark in audio reproduction. Notice that I didn’t say “digital audio reproduction.” In other words, in my view the PS Audio DirectStream is the most musically and technically capable device of any type that I’ve ever had the pleasure to evaluate. My heartfelt congratulations go out to Paul McGowan, Ted Smith, and PS Audio’s excellent design team for making DirectStream a reality for those of us who truly love our music."

"At nearly $6,000, DirectStream is not inexpensive, but by today’s standards for the wealth of musical improvement it offers, I consider it a bargain. Personally, I had to stretch my budget to buy the review sample, but frankly after hearing the immediacy, dynamic capability, and immense soundstage that DirectStream provides I couldn’t bear to send it back."

The new PS DSD DAC is maybe the best DAC made, regardless of cost. It uses an FPGA, a field programmable gate array, which is basically a computer on a chip. It takes CD’s, downloads, high-resolution PCM or DSD based media  and upsamples them to ten times DSD rate and outputs a pure analog signal directly into your amplifier or preamplifier. DirectStream converts any digital input format, such as PCM or DSD to a pure 10x DSD stream and outputs near-perfect analog directly to your power amplifier or preamplifier.

DirectStream has seven digital inputs which include: two I2S, one TOSLINK optical connector, one coaxial S/PDIF connector, one balanced XLR AES/EBU, one asynchronous USB input and one optional Network Streaming Bridge slot.  DirectStream has both single ended coaxial and fully balanced XLR outputs.

The DSD DAC was 7 years in design and will start shipping in late April. It is easily the best DAC that we sell. The first production is sold out. Call me to get an order placed for May or June shipment.

If you own a Perfect Wave DAC or DAC MK2 they are upgradable to the DSD DAC. The kit is $2995.00. Call me to discuss this as well. We have a few new Perfect Wave DAC MK2’s at $1880.00. Add the upgrade kit and you have a new DSD DAC for $4880.00.
