Manufacturer's Comment

Thanks, Michael, for yet another thorough and entertaining review. The fact that it is hugely positive comes as no surprise for us (not to sound boastful) as Ted and our crew worked hard to ensure that DSJ combines the leading-edge sound quality you'd expect with traditional PS Audio value.

Just like the DirectStream, DSJ is obsolesence-proof, as its FPGA can be updated by the owner with new firmware at no additional cost. DAC-shoppers should also realize that DSJ is more than just another DAC: the standard inclusion of our Bridge II and a superb volume control make DSJ a complete front end component. Comparing the cost of DSJ to cost of other DACs PLUS a streamer/server PLUS a linestage shows just what a killer value DSJ really is.

It's always a joy for us when a user really understands one of our babies. The fact that you really get DSJ, and are able to convey that so eloquently to thousands (maybe millions!) of readers, makes it even sweeter.

Thanks!—Paul McGowan, Founder and CEO, PS Audio

How does the Directstream Jr compare to the Cary DAC 200ts also oneof your Favourite Bits items?

Oops you've retired the Cary so I guess you prefer the Directstream Jr. I was intrigued by the descriptor "wet" as that would have been something I associate with a tubed unit like the Cary.

With respect to: "but when compared side-by-side to the PS Audio DAC, the Vega takes a few steps in the direction of digital."

I'm not sure there is a "direction" preferable for either analog or digital, or what the words might mean to any ear, or is to be interpreted as.

Analog is not a place to go or get to; it is not preferable and it is not "better." If it were better, than we'd see the entire recording industry and recording chain go there to get to it. Analog is not THE standard.

Digital is not a standard either to go or get to, or away from. It were something to get away from on the basis that it is "worse," most of us would be getting away from it.

The standard is the line or mic feed from the same musicians/studio and microphone fed by y-connectors to the monitor and two recorders: one analog, the other digital. The bypass of either provides for the contrast between the two recordings, and the recording closer to the bypass is the standard. To the best of my knowledge in cases where such tests were conducted, the digital recordings won hands down - being closer to the live sound via mic feed.

Therefore I respectfully propose we rethink our positions rationally in the context of a hundred and then-some year old technology being supplanted by a hundred and then some year newer technology that is measurably, scientifically, and in the right system audibly, superior to what came before.

This, in the same sense, using the same technology more or less, we see in digital imaging, 720i to 1080p to 4K, 5K and 8K...parallel technologies operating in unison to make the immersion experience possible. The probably question has been left behind in the rear-view mirror.

The possible is here now, the impossible is around the corner, and that, will be the possible of the tomorrow.

The place we will go to and eventually get there.

...that you can respectfully propose whatever you like. Here at AudioStream, we review things that exist. We do not review theories or ideas. Since sound waves are not digital, analog is the ideal. At least that's the way I see and hear it.

I proposed in the eighties the slogan "Digital Sucks." It did. It no longer does, otherwise we'd all abandon it instead of moving ahead to adopt it. I was crucified for my views, which is what happens when one proposes respectfully anything unconventional.

We optimize our systems to whatever source we use. Most of us long in the tooth have long ago optimized our systems for analog - as have I. Yes, I have a high end analog system too. And a large LP collection, much of HP's list, I wish someone would buy. Others have optimized theirs to digital.

I happen to know a number of high end reviewers who have done both. One in particular has the very same analog system as an analog guru working for your sister publication. He said his high end digital system wiped the floor with his analog system. I trust his ears, and his system, because he has no skin in the game, in contrast to the analog guru who has.

The high end journals exist because they sell advertising space. The reviewers exist because they get equipment at accommodation and get paid for writing. Much of the high end industry, specifically the sector selling the most expensive products, advertise analog products from which they make a living. The pages of the journals are filled with these ads.

A number in the letters to the editor have argued that these products, besides being unnecessary for good sound, are obscenely overpriced. Watching the escalating prices over decades (and having heard many of these), I tend to agree with their assessment - even in the face of ridicule and respectful propositions that a $10,000 cartridge and a $150,000 turntable is priced reasonably. This tactic works rather well when the proposer compares the $200,000 analog front end to a $500 digital front end.

Poorly assembled and poorly optimized digital systems suck. The same can be said for analog, although analog so lacks transparency and dynamic range, that it is far more forgiving to the ear. Both have their own, individual, audible distortions. Arguably analog has an order of magnitude more of it and an order of magnitude more noise. That, is just plain science. If one enjoys listening "through" the grinding surface noises, ticks and pops, swishing sounds, muddy bass from structure and air born feedback, and one can argue he hears these noises live, he's abetter man than I. Personally, respectfully, I'd rather not have to listen "through" any noises I don't hear in live music.

And these words are coming from a former subjectivist reviewer. Meaning, probably as opinionated as you.

I say, being a strong believe in freedom, whatever spins your wheels, analog or digital, go for it.

My first choice is sushi with warmed saki and a good nap afterward.

I assure you, lastly, that sushi, saki, a good nap, and a good digital system I enjoy daily, exist too. We all should enjoy the music for the thrills it has given us repeatedly through the years, regardless of our choice for transmission of it...though not quite the thrills I get @

The subject of that article is both an audiophile and a music lover. And besides hanging out with him and our wives in the summers I listen to live music, orchestra and opera and jazz daily - for months at a time. My open window fronts the most beautiful opera house in Europe from which, in addition to concerts I attend, we get daily recitals. And just a couple of blocks away is the Franz Liszt Conservatory my concert pianist sister attended for years in her youth, which was before my youth, and which I visit daily. The most important part of this discussion is the nature of one's familiarity with live sound v the reproduction of it. I respectfully propose the last too. :)

But thanks for that, um, story.
"The high end journals exist because they sell advertising space. The reviewers exist because they get equipment at accommodation and get paid for writing."
You missed the most important part of this equation: the reader. Accommodation price is, in my experience, a really silly argument since anyone and everyone can buy used and demo gear which works out to be about the same. And I existed before I got paid to write for AS ;-)

From your description of listening to records, your vinyl rig must not be set up properly and/or your records must be in very poor shape ;-)

I'm not into the part of our hobby that says things like "wiped the floor" and other such overly competitive nonsense. I'm talking about listening to and enjoying music. Simple, humble, universal, without the need for egos that leave no room for thoughts other than their own.

Sounds like you have a lovely view.

Hi Michael

Your views please on the differences in sound between the Cary and the Directstream Jr? Why did you prefer the latter?

Michael Lavorgna's picture
...I feel the DirectStream Junior is more fleshed out, more natural sounding, and more engaging over time. It's also worth noting that since the digital processing in the DSJ can be updated via firmware, there's the possibility for free future upgrades that may add functionality or sound quality improvements.
mikey8811's picture

By fleshed out, do you mean the DS Jr is fuller sounding than the tubed Cary or that there is more definition and detail in the body while the latter is full and "warmer" in the traditional tube sense and hence more euphonic and less natural sounding?

Sorry for adding more words to your already precise definition but just wanted to pin it down.

Michael Lavorgna's picture
...words about sound become like snakes; hard to get a hand on without them wriggling away or biting you ;-)

Both of these DACs can be purchased direct with a 30-day return policy so my advise, if you are not sure which you'd like more, is to listen to both in your home.

mikey8811's picture

Not in Asia...

That's why reviews tend to be important to us.

Michael Lavorgna's picture
This may help with a recommendation.
mikey8811's picture

My system is:

Auralic Aries -> Mark Levinson 36 DAC -> Cary SLP 05 pre -> Pass Labs X350.8 -> Vienna Acoustics The Kiss speakers

I read your review of the Cary with much interest as you were using a Pass Labs 0.8 series integrated albeit an XA one. Also, I was attracted to the Cary because of the possible synergies with the preamp. I see you have moved on to the Ayre AX 5 Twenty now. My impression of Ayre (non Twenty) vs Pass was it was leaner, was more refined, had more microdynamics but had less bass slam. It was also slightly rolled off at the top - FWIW so you can gauge my tastes.

I generally prefer a warm, full, sound with harmonic richness and tonal density. Music preferences are jazz and I am sensitive to brightness in the highs, especially on less pristine recordings of brass instruments. Am willing to sacrifice some treble roll off.

Thanks again

Michael Lavorgna's picture
I think you'll be happy with the Cary, all things considered ;-)

a bunch ...

Hi Michael, Big fan of your reviews... Just curious if you have a follow up planned now that the bridge II is roon ready. Would love to hear your opinion on sound quality vs. the micro rendu/ sonic transporter set up. Thanks man!

Michael Lavorgna's picture
I sent the DSJ back right after the review so there's no follow up planned.


TJ's picture

the DSJ is limited by noise to 16 bit resolution? Note the bench test in the current issue of HFNRR which measured an A-weighted S/N of 93 dB at its outputs, consistent with the high noise floor seen in their test data. Even if the DSJ can process signals internally at 20+ bits, that resolution is lost in the noise at the outputs.

Michael Lavorgna's picture
These measurements do not change what I heard and reported on.
TJ's picture

Perhaps the DSJ is quieter than your integrated amp. Ayre doesn’t publish the SN of the AX-5 Twenty, but JA measured the AX-5 at 14-15 bits (86dB) A-weighted.

Bill Leebens's picture

This question is above my pay grade, so I went to Ted Smith with it. Ted responded:

"There's a difference between resolution and S/N ratios. The resolution limit is the level where changes on the input don't affect the output: for the DS (or DS Jr) the signal to noise may be around 17-18 bits (-102dB to -108dB) but, for example, in Stereophile's measurements (March issue 2015 (Vol.38 No.3))) figure 4 shows the results of a signal at -120dB If the resolution were only -108dB then figure 4 should look flat or at least not look anything like the way it does.

"Clearly the resolution is better than -120dB. It's a pity that people aren't more careful using the words "resolution" vs. noise floor vs. S/N ratio - as an example adding dither increases resolution at the same time as it decreases the signal to noise ratio.

"There are also differences in quality depending on the character of the noise. White noise is easily filtered out by the ear/brain. Noise correlated with the signal can affect the perception of the character of the sound. The figures in the Stereophile show a fairly white noise floor."


Bill Leebens, Director of Marketing, PS Audio

Michael Lavorgna's picture
..but I think Ted agrees with me ;-)
TJ's picture

“It's a pity that people aren't more careful using the words resolution vs. noise floor vs. S/N ratio.” Gosh Ted, don’t know what to say… these are the definitions I'm using:

Somehow this thread has turned into a defense of the DSJ, whereas my question was broader and never intended as an attack. So let me try again: how quiet do electronic components need to be to allow listeners to hear the difference between 16 bit and 24 bit recordings? (there, no careless terms.) Vendor neutral.

John Atkinson has said what he thinks: “The 16-bit CD has a noise floor at -96dB and change, hence cannot resolve information lower than -96dB. By analogy, an amplifier with a maximum signal/noise ratio of 96dB would, if its noise floor were random, have 16-bit resolution.” (Stereophile bench test, Benchmark AHB2). Likewise for John Saiu of Benchmark, Bob Stuart at Meridian, and others who say “how quiet? very quiet”.

It would be helpful for us audio consumers out here to understand what circuit designers think who build best-in-class DAC and amp products which happen to have SN at the outputs that measure worse than 96dB (oops, I did it again… peace to all). Perhaps they see this question differently?

Michael Lavorgna's picture
It is a response to your questions about the DSJ. Make no mistake -- you made this conversation about this DAC. If you don't believe me, just read your original comment ;-)
TJ's picture

My bad, poorly worded... the HFNRR review got me thinking, and if I had given it further thought, I would have added "or any other DAC with a similar SN measured at the outputs." My reworded question is more carefully stated.

Michael Lavorgna's picture
...that if I have a question that I'd like to get answered from someone who doesn't owe me an answer, it's best to just ask the question and leave all the baggage at home.

Thank you Michael for posting Bob Stuart's technical summary which is so interesting and helpful. I found answers there to the questions that I asked above. I'd also like to thank you for reaching out to PS Audio in response to my original question, and Ted for his quick reply.

Michael Lavorgna's picture
I'm very happy to hear that you found Bob Stuart's article helpful. I did too.

Old post so not sure if anyone is still listening - Michael Lavorgna would love to get your insight if possible. I currently have the PS Audio DirectStream Jr (DS Jr) and the Wadia di322 at home now for a trial. I was looking to upgrade from my Benchmark DAC2 HGC (BMD2) as in my system it was not as musical as the Wadia CD Player it replaced when I converted to all digital media. I completely agree with your comments on the sound of the DS Jr and I like it a lot more than the BMD2 so decision was easy until I added the Wadia to the mix just a few days ago. To me the Wadia was just as smooth and musical as the DS Jr but it seems to highlight/amplify more of the nuances in the music – so overall seemed a bit more musical to me. This might be just trickery that plays to my particular hearing defect (I am a little impaired at higher frequencies) so would like to know what you think if you have any experience with the Wadia di322 or even the di321.

For reference: the rest of my system is Lenovo x201 laptop running JR River MC -> USB Cable -> DAC -> Kimber Silver Cables -> Music Reference RM-9 MKII Tube Amp -> OCOS Cables -> Vanderstein CE2 Speakers.

I also was considering upgrading my pristine Benchmark DAC2 HGC to the PS Audio DS Jr. The Benchmark is just a little too harsh for me. I previoulsy had a PS Digital Link III DAC, and loved it. Let me know if you have any feedback. Thanks, Plonk

BuckChaser's picture

Try searching (The hunt for an excellent sounding DAC continues - help please) and ou should find my detailed comments /comparison on the BM DAC2 vs the PS DS Jr with the Wadia di322 thrown in for good measure. Good luck.
