Take 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.

That alone is a major accomplishment. Maybe we had been lulled into a bit of been-there-done-that reviewer fatigue but the DirectStream's handling of this CD became a rude wakeup call and put us back on edge to eat crow. Notice that I didn't say "digital audio reproduction. It is smooth and relaxing. Surely, you tell yourself, it must be sacrificing detail to deliver this. But no.

With recording after recording, the DirectStream presents layers and layers of detail in such a way as to produce a sound which is very easy to listen to, and with a low fatigue factor, even with CD sources. As someone with very little tolerance for the fatiguing nature associated with CD, I find this to be a most appealing characteristic. Enlarge image. 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. Included IR remote. Silver or Black Network Bridge II optional - please select from below options if you would like one on board.

Pure DSD done right. Hand written, discrete, perfection based conversion that uncovers all the missing information hiding in your digital audio media for all these years.

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. In , 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.

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 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 fulfil the promise of analog's century of dominance for sounding like music and PCM would not be it. That answer is DSD. 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. 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 favour of a significantly more musical sounding format, DSD. 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. 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. Converting PCM to DSD properly,and in such a way as to reveal missing details in the music, is a serious technical challenge. To handle this properly DirectStream utilises bit fixed-point FIR filters, eliminates headroom issues common to PCM, flattens noise response in the kHz region, uses coefficients optimised for best sound rather than faster processing speed and optimises hardware-specific operations not possible in software.

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. The results of this design can be heard in increased musical information presented to the listener at every opportunity.

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. 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.

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 synchronise 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 synchronisation is eliminated, jitter levels are reduced and music is delivered with a clarity rarely heard. 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. 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. 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. 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.

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. 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.

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. 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 realised are even there.

CDs come alive with subtle details that were never apparent with your older DAC; details you never knew even existed. 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. 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 aluminium 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.

The body of a year-old girl who went missing in Quebec's Eastern Townships and was the centre of a police search in recent days has been found. A Montreal infectious diseases specialist is leading a new COVID vaccine trial testing the Moderna vaccine on six-month-old to six-year-old children, the last and youngest group of kids to be eligible for vaccination in Canada. The string of deaths in a tight-knit community in Laval is exactly the kind of scenario that Montreal-area public health officials have been trying to avoid, for months, by finding and swaying groups with high vaccine resistance around the city. Complete Weather Forecast. Some bars in Montreal are struggling to keep their shelves stocked and sometimes their best seller is whatever they have left.

PS Audio - DirectStream DAC

ps audio direct stream dac review

TAWW Rating : 4. Hugely resolving, relentlessly musical, highly versatile, sanely priced - my new reference. PROS: Detail and naturalness in perfect harmony; highly upgradeable; versatile input and streaming options; nice looks and solid American! I received the review unit last summer, and first impressions were strong. Then some sonic gremlins reared their heads, and I was advised to hold for a software update, called Redcloud.

My Thoughts.

PS Audio DirectStream DAC ($9860 with Bridge II streamer)


But google is your friend: for both digging up the article and translating it surprisingly well! Anyway, sharing the info here for those who might be interested and unaware of the comparison. For an all Naim system, they preferred it, and for classical they seemed to prefer it. For Diana Krall they might have preferred Metrum… a backhanded compliment if you ask me. No preamp… Some will say this further disadvantaged the Naim, as it should be driving a preamp.

Six years after its introduction, PS Audio's DirectStream DAC remains our top pick for anyone cutting over from vinyl to digital for the.

Read honest and unbiased product reviews from our users. In short, a receiver can be your HDMI switch, a DAC digital-to-analog converter , an audio processor, a multi-channel amplifier, and a radio tuner built into one. I'm wondering if headphone amps are actually better at powering good headphones something like Sennheiser HD than a mid to upper range AV receiver would. A DAC, or Digital to Analogue Converter, is a unit which converts a digital audio signal, such as that from a CD player, television or computer, into an analogue one for connection to a standard amplifier.

The Colorado manufacturer has this week announced the availability of a new and final firmware update for the DirectStream and DS Jr. In lieu of a press release proper, PS Audio has made a video to explain the Sunlight firmware development story in more detail. John currently lives in Berlin where he creates videos and podcasts and pens written pieces for Darko. Follow John on YouTube or Instagram.

I received some emails encouraging an audition. PS Audio will never charge for software upgrades.

From one of the more useful comments on the PSA site I do think that thread was worth reading. In terms of context, it appears most of the response to the review is that the measurements are mostly "bad" because of the DSD's high noise floor, which is an inherent part of the design. Unfortunately this approach necessarily will have a higher noise floor than will most other approaches. The DS on the other hand takes all input signals, up-samples the input to 20x DSD and then passively low-pass filters the output, thereby transforming it into analog. And it is, by all accounts, supposed to be the very best sounding DAC that anyone who has heard it has ever heard. Unfortunately the price for this particular very deliberate engineering design decision is always going to be a higher noise floor.

A few boxes come to mind, but they are mostly DACs. And some of us still want to play shiny discs; some of us have big collections of shiny discs. Even DVD-a shiny discs.
