PREOWNED - $6000 LIST! - FULLY TESTEDRemote includedDesign DirectStream converts every input signal, both PCM and DSD, to single-bit, high sample rate 20X DSD signal. Use of a FPGA rather than an off the shelf DAC chip provides immense processing power, resulting in complete lack of digital glare, and allows the owner to download OS updates as they are released. Application DirectStream is the heart of a reference quality digital audio based system. It handles all PCM sources up to 352.8 kHz, and DSD 64 and 128 (USB and I2S) and DSD256 (I2S only, with the Sunlight OS). Its zero-loss digital volume control allows it to be used as a preamplifier, directly feeding a power amp. Include the Network Bridge to stream Qobuz, Tidal, and Spotify. Roon ready. Class A+ Stereophile rated DirectStream DAC converts any digital input format from CDs, servers, and streamers, into a pure DSD format and outputs near-perfect analog directly to your power amplifier or preamplifier. Whatever the format, sample rate, or the medium, DirectStream provides a pure output that fulfills the promise of high-resolution analog performance from digital sources. DirectStream is the work of digital audio genius, Ted Smith. Unlike conventional DACs that rely upon off the shelf DAC chips, DirectStream is hand written onto a FPGA (Field Programmable Gate Array). This allows far more precise and accurate processing of the digital signal, resulting in significantly better sound quality and upgradeability in the field. Every six months or so, Ted Smiths continual research into digital audio reproduction nets another breakthrough in performance. DirectStream DAC owners are given it free in the form of a downloadable upgrade. In this way, DirectStream owners can be assured that their unit will continue to improve over time, and never become obsolete. Hear what’s been missing in your music for all these years. If you know the sound of music and instruments, and want to hear what’s been missing on your discs, then this DAC is right for you. Converting the ones and zeros of digital audio into music we cannot distinguish between live or recorded is an art. Most of today’s sophisticated DACs are IC based instruments using off-the-shelf-chips that rely upon Multi-bit Sigma-Delta functions to process the incoming digital audio. While these are relatively simple to design and produce, they rarely give the best sonic results. DirectStream takes a different approach by first converting all digital audio signals into a purer form of digital audio known as DSD. DSD is a far more analog-like encoding and decoding process than the classic CD based PCM. In fact, most modern A/D converters used to make recordings are DSD based already. 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. 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. 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 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 that is fed directly into the DirectStreams zero-loss volume control. 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. The ability to eliminate the preamplifier in the system without any resolution loss is a major benefit to DirectStream’s outstanding musical performance. Imagine going to a recording studio and listening to a master tape of any recording made. This is the experience DirectStream provides its owners who enjoy a renewed sense of enjoyment and discovery when listening to everything in their library: CD’s, downloads, DSD.

CD’s, high-resolution PCM or DSD based media are expertly upsampled in the DirectStream to ten times DSD rate and output as pure analog directly into your amplifier or preamplifier.Introducing DirectStream DAC, both Stereophile and Absolute Sound’s Product Of The Year. Hand written, discrete, perfection based conversion that uncovers all the missing information hiding in your digital audio media for all these years. CD’s, downloads, high-resolution PCM or DSD based media are expertly upsampled in the DirectStream to ten times DSD rate and output as pure analog directly into your amplifier or preamplifier. Classic PCM based DACS, including many of today’s DACS that can also process DSD, tend to cover up some of the subtle musical details buried deep within digital audio music; a problem inherent in their architecture. DirectStream solves this problem by employing a pure DSD single-bit approach for both PCM as well as DSD media. This means that your entire library of music can finally reveal all the music and subtle low level details buried deep within its core. Imagine going to a recording studio and listening to a master tape of any recording made. This is the experience DirectStream provides its owners who enjoy a renewed sense of enjoyment and discovery when listening to everything in their library: CD’s, downloads, DSD.Class A+ Stereophile rated DirectStream DAC converts any digital input format, such as PCM or DSD to a pure DSD stream and outputs near-perfect analog directly to your power amplifier or preamplifier. Whatever the format, whatever the sample rate, DirectStream is a pure DSD based solution that fulfills the promise of a high-resolution analog performance standard the originators of CDs promised over 30 years ago. Hear what’s been missing in your music for all these years. If you know the sound of music and instruments, and want to hear what’s been missing on your discs, then this DAC is right for you.Pure 100% single bit DSD based D to A ConverterMost 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 stageMost 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 controlsDesigner 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 clockTypical 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 sourcesSources 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 USBDirectStream 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 inversionA 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 preamplifierDirectStream 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 CDsDirectStream 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.The start of the 30-year warIn 1981, music was reproduced exclusively on analog-based turntables and tape decks with limited dynamic range.Despite the very listenable music coming through those grooves, the audio world wanted more: greater dynamic range, lower noise, extended frequency response. No wonder that when, in 1982, Sony and Philips announced they had achieved “Perfect Sound Forever”, music lovers around the world waited in eager anticipation of analog’s promise finally fulfilled. Unfortunately those early CD’s sounded less musical than analog. In some cases, much worse. The launch of the PCM-based Compact Disc would set in motion a 30-year war amongst Audiophiles, decimate the analog format, cover up subtle musical details for decades and turn the music and audio industries upside down –and not necessarily in a good way. There had to be a better way to fulfill the promise of analog’s century of dominance for sounding like music and PCM would not be it. That answer is DSD.Fundamentally betterThe poor results of the first CD’s might not have been a problem if Sony and Philips had waited another decade, passing over the classic PCM delivery system in favor of PDM (DSD). The problem is the PCM decoding process itself: whether a classic ladder-DAC or more modern multi-bit Sigma-Delta type, most PCM playback processors mask some of the subtle cues in music. Fortunately music’s details have been more faithfully recorded than we ever suspected, but the cover-up of those recorded details has been with us for more than 30 years. Happily, the missing musical information is still buried deep within our audio libraries—waiting to be revealed. In order to extract everything hidden in PCM recordings, a completely new processing method is needed.Pure DSD is the answerPut DSD into DirectStream, you get DSD. Put PCM (how CD’s are recorded) into DirectStream, you get—DSD. DirectStream converts all digital inputs, including PCM, to pure 1-bit DSD, in an elegantly-simple path. In the process, the PCM feed becomes more linear, less edgy, and never-before-heard musical details are released from all digital audio recordings. Billions of CDs and high-resolution downloads worldwide will gain new life, and be saved from obsolescence. There’s a notion floating around high-end audio circles that DSD may be nothing more than a passing fad. In fact, we would suggest the opposite may be true. PCM based music decoders are nearing the end of their lifecycle in favor of a significantly more musical sounding format, DSD.A better formatDSD is a high sample rate single-bit format while PCM is a lower sample rate many-bit format. DSD sample rates are 64 times higher than those used to create CDs and the output of a DSD stream can be placed through a simple filter to produce pure analog ready to feed your audio system. PCM, on the other hand, can produce great sounding music but to do so requires a very complex and technically daunting conversion process to produce something you can play on your system. Sometimes the simplest path is the best sounding one. DSD is a far more analog-like encoding and decoding process than classic PCM. In fact, most modern A/D converters (used to make the recordings) are DSD based already and that movement is growing. There are millions of PCM based recordings that will be in our libraries for years to come, but with the introduction of DirectStream, you no longer need listen to them with a PCM based processor.The secret is in its simplicityTake a look at this comparison diagram: on the top is a block diagram of one of the best PCM-based processors in the world. Notice the circuitous path taken by the audio data stream to the output of this converter. Then look at the pure simplicity of the DirectStream. The PCM processor’s tendency to mask music’s subtle details is largely due to its complex needs, and the technical requirements of PCM processors.Converting PCM to DSDConverting PCM to DSD can be an easy exercise using any number of computer software programs. Converting PCM to DSDproperly,and in such a way as to reveal missing details in the music, is a serious technical challenge. To handle this properly DirectStream utilizes 66-bit fixed-point FIR filters, eliminates headroom issues common to PCM, flattens noise response in the 20-100kHz region, uses coefficients optimized for best sound rather than faster processing speed and optimizes hardware-specific operations not possible in software. Unlike other processors available today, DirectStream unifies all inputs (PCM or DSD) at 10 x DSD, then uses a true single-bit double-rate DSD core engine. True DSD core engines (compared to the standard multibit Sigma-Delta converters followed by random lower quality multibit converters) offer advantages in simplicity, linearity, and in analog-like overload characteristics that avoid PCM’s “hard clipping” potential and a PCM processor’s propensity to mask subtle details.DirectStream is built in the United States by hand. Local manufacturers use sophisticated PCB building machines to populate and test the multi-layer boards used in DirectStream. It takes a number of companies and a lot of skill and equipment to build something this sophisticated. From high tech x ray technology to place the FPGA IC on the board, to automated pick and place machines to add parts in just the right spots, each of the four PCB’s used to build a DirectStream are built, tested and delivered to our Boulder Colorado facility by handpicked US vendors. The chassis of DirectStream is a metal sculpture that is by far the best we’ve ever built. A combination of aluminum and steel, DirectStream weighs in at 20 pounds of elegance and beauty. The top cover is a hand painted, hand polished piano black high density material that has been lavished over for hours. And has the look and feel of a fine Steinway piano. The PerfectWave series is assembled, programmed and tested at our production facility in Boulder Colorado. There is a measure of pride of workmanship that goes into every one of these PerfectWave products and it shows from the moment you open the unit up and plug it in. This is one gorgeous piece of equipment and just the beginning of the most beautiful natural sounding audio equipment you have ever had the privilege to own.DirectStream is the culmination of one man’s quest for perfection coupled with one company’s search for the same. Principal designer Ted Smith put more than seven years of work into designing what he hoped would be a new standard for musical reproduction without any audible problems. Five years into the development process he wanted to evaluate DirectStream’s performance against the very best in the world and turned to the principal SACD mastering engineer, Gus Skinnas for help. Gus, who has personally mastered many of the SACDs in the world and worked directly with Sony designing and building both the state-of-the-art Sonoma DSD mastering system and the Super Audio Mastering Center, invited Ted to bring over his prototype DAC to compare with the very best the world of high-end professional mastering equipment had to offer. Ted wasn’t disappointed and Gus was blown away at what he heard. The prototype bettered anything Gus had in the studio for mastering and on the spot decided to call his friend, Paul McGowan, CEO of PS Audio. At Gus’s urging Paul met with Ted at the Mastering studio, heard the DAC and Paul immediately signed Ted on to PS Audio’s team to build this creation into a PS product. Two years of working with PS Engineering, hundreds of hours in the listening room by Paul McGowan and Arnie Nudell (founder of Infinity Loudspeakers), many hundreds of hours more of tweaking, tuning and care lavished on the product and the results are here today in DirectStream. DirectStream is one of the most worked on, labored over and perfected pieces of audio instrument in the world today. It is capable of uncovering details in your recordings you never knew existed. DirectStream represents the best in American ingenuity, craftsmanship and care. DirectStream will enjoy worldwide recognition and local handcrafting in Boulder Colorado.Pure 100% DSD based D to A ConverterResolution perfect volume and balance controls built inUpsamples PCM and DSD to 10x DSD ratePurely passive transformer coupled outputImproves imaging and soundstageSimple, direct signal path with one master clockHand written filters, processors and upsamplersImmune to incoming jitter problems from different sourcesIncreased digital headroomNo off-the-shelf IC DAC chips usedUncovers musical details masked by typical PCM based processors7 digital inputsFully balanced from input to outputColor touch screenOn Aug-28-23 at 14:13:55 PDT, seller added the following information: Edit: This is Mk1 dac https://www.psaudio.com/products/directstream-dac?gc_id=20382175359On Aug-31-23 at 18:25:50 PDT, seller added the following information: Update: I installed the latest update from PS Audio on this machine after I listed it, but before pulling it from my system.
