DAC Comparison Showcase

Y’all are far more conversant than I am when it comes to the technical aspects of dCS and its DAC products. Some of us, though, tend to focus primarily on the musicality and overall sound quality of a system without spending quite as much time worrying about external streamers, file servers, interconnects, USB or Ethernet cables, and so forth.

Please understand that I am definitely NOT suggesting there’s anything wrong with doing so, different horses for different courses. I simply appreciate the relative simplicity of what my Rossini APEX can do in my system and, more importantly, just how truly great it sounds.

Here’s something from almost the opposite end of the technology discussion that I thought might be interesting to fellow dCS owners.

The Colorado Audio Society did something pretty fascinating this past Saturday at our monthly meeting. We held a showcase of different DACs representing the remarkably broad range of price points in today’s marketplace (without prices going over the top). For those who may not know, CAS provided much of the volunteer backbone and local community support that helped make the Rocky Mountain Audio Fest (RMAF) such a terrific gathering for audio enthusiasts from across North America for so many years. We greatly miss having RMAF in our backyard.

Before anyone condemns the exercise because of the inherent shortcomings of A/B/A testing, let me say that the organizers went to considerable lengths to make this a fair and credible blind audition. The 30+ attendees were able to judge the sound quality of each DAC without knowing which brand or model they were hearing. The process itself was quite methodical and took several hours to complete. We worked our way through the DACs sequentially: 1 vs. 2 vs. 1, then 2 vs. 3 vs. 2, followed by 3 vs. 4 vs. 3, and so on through all 10 units with a short needed break in the middle. So, while the individual musical excerpts were necessarily brief, each DAC was heard repeatedly and in direct comparison with the next one in the sequence. By the time we finished (each DAC was heard 3 times), everyone had spent several hours listening, comparing, and forming their impressions as they scored each DAC in 10 different assessment categories.

They also did an excellent job of creating as level a playing field as possible. The same inputs, interconnects and power cords were used throughout, and the output levels of the components were carefully level-matched. In addition, the organizers prepared approximately 30–35-second excerpts from six different songs so that everyone heard exactly the same musical selections through each DAC.

The selections covered a wide range of music: solo female voice; male voice accompanied by acoustic guitar; a symphonic selection; techno; big-band jazz; and rhythm-driven rock. The excerpts were deliberately chosen to provide a good cross-section of musical styles and to exercise the full audio frequency spectrum. Although 30–35 seconds obviously isn’t a long time, the selections gave us an opportunity to listen for how each DAC handled the treble, midrange and bass individually, as well as how naturally and coherently those ranges came together as a musical whole.

A call had gone out beforehand asking CAS members who would be willing to furnish their DAC for the comparison, and please note that I am purposely avoiding the word “shootout,” because the purpose was not to declare winners and losers. Ultimately, 10 different DACs were offered up, including both solid-state and tube designs, with retail prices ranging from approximately $350 to $34,500.

Needless to say, the results were pretty interesting and, in some cases, surprising. Twice during the testing I wrote in my notes “that’s mine!” Once I was spot on and the other, well, its a pretty great DAC too.

The DAC I supplied was my Rossini APEX, but without the Master Clock. I made the case that the clock was needed to let the Rossini sing at its resolving best, but the organizers quite reasonably pointed out that none of the other DACs would have the benefit of an external clock and they wanted to keep things as even-steven as possible. So I smiled, said that was fine, and figured, let’s just go with the Rossini sans clock and see how it does.

Well, it did pretty darn well.

I’m not going to list the brands and models of the other DACs in the comparison, since the purpose of the exercise wasn’t to call out winners and losers. But rest assured, there were several well-known and highly regarded names represented at the upper end of the price spectrum. So the Rossini certainly wasn’t competing in a vacuum.

In short, the Rossini emerged as the clear favorite among the participants. (There really wasn’t a “winner” per se, that wasn’t the purpose of the exercise but I’m characterizing it that way for simplicity’s sake.)

When the group was polled, most raised their hands in favor of the dCS unit. The general view was that it provided the most complete, musical and listenable presentation, while at the same time offering the best-resolved view into the music and a compelling sense of realism.

I’m sharing this not because a single blind comparison proves that one DAC is definitively “better” than another. It doesn’t. But it’s not often that we get the opportunity to hear something we hold in very high regard – namely, our dCS components – and how it is received by a group of experienced listeners who have no idea what DAC they’re listening to and no brand or price information to influence their impressions.

For me, that was the most interesting part of the afternoon. I already knew how much I enjoy my Rossini APEX in my own system. Hearing a room full of experienced listeners, under blind conditions, respond so positively to the same qualities I hear in it was both gratifying and reassuring.

Mostly, though, it reminded me how fortunate I am to own a Rossini APEX and to have it as part of my stereo system.

And yes, when I got home, I hooked the Master Clock back up.

A really interesting read @ksweiss, and gratifying for us (and no doubt for you) that you preferred your Rossini even in a blind comparison with some worthy competition. As you point out, exercises like this are complex, logistically challenging and time consuming, and consequently something very few of us ever get the opportunity to try. Thanks for sharing!

Very interesting. Thanks for posting this! :folded_hands:

I have no doubt a “sighted session” would have produced very different results :laughing:

Hello @ksweiss,
Which DAC/brand was it?
Also, have you been somehow impressed by the sound quality of a “budget” device?
:wink:

Great info and would be more knowledge if you could name couple of other populars too but okay if others diagree here.

I can share just a few that really stood out to me, although for different reasons. But before I do, I should probably make one thing clear: the Rossini still came out on top for me and the majority who were listening. And, if a system admin needs to remove this post because I’ve mentioned other brands I am okay with that. (That is why I was hesitant to do so at the outset.)

  1. Lampizator Pacific 5 DAC – I really liked this DAC. At least in this blind test, its SQ reminded me quite a bit of my Rossini in terms of clarity, realism, and simply sounding right. It also had a wonderful musicality that would make it very easy to settle in and just enjoy the music.
  2. HoloAudio May DAC – This was another one I really enjoyed. It had plenty of resolution and detail, but didn’t strike me as overly analytical or clinical. It still had a nice analog warmth to the presentation, along with very natural tone. Overall, I’d put it just a notch behind the Lampizator, but it was still one of the DACs that stood out to me in the test.
  3. Topping D90 SE – This was probably the biggest surprise for me. At around $900, I thought it sounded remarkably good. It also made me wonder: with my Rossini APEX retailing today for roughly $34,500 (certainly not what I paid for mine a few years ago), did it sound 38+ times better than the Topping? I honestly can’t say that it did. Was the Rossini clearly better to my ears? Absolutely. But was the improvement anywhere close to proportional to the difference in price? Probably not. Then again, I think most of us who have been in this hobby for a while understand that diminishing returns are very real as you climb the sound quality/price ladder.

That said, the Rossini isn’t going anywhere. A few of these DACs sounded really good, but the Rossini has become such a great fit for my system and, more importantly, for the way I like to listen to music and for what I like to listen to. At some point, finding something that musically simply works in your system matters more to me than wondering whether something else might measure or sound a little better.

For me, that’s what made the blind test so interesting. Take away the brand names, reputations, and price tags and just listen and you can end up being pretty surprised by what you hear.

Price obviously is a factor and so it should be, but dac’s have come on quite a bit over the last few year’s, thats why dCS keep on developing and pushing things forward. Don’t forget the Rossini will soon be getting a nice free upgrade that will push it forward even more. Ownership is also more than just the sound, its the team and support behind it that also matters hugely, and when needed are there for you. I am pleased to say dCS are also excellent in this department.

It’s great to be able to pick out your dac in blind testing, plus other’s also picking the Rossini, it shows you made the right decision.

For office/workshop use I needed a DAC with broad connectivity which wasn’t going to cost a fortune and, having waded through the treacle which constitutes Topping’s naming of its D90 variants, I bought a Topping D90 III Discrete based purely on web reviews of its sonic signature.

I have to say it performs way above what I expected for the £900ish price (and, it has to be said, setting aside my brand cynicism rooted mainly in ASR’s measurist love for the breed). My own Rossini Apex is going nowhere of course…


These comparisons are very interesting. For the sake of completeness, it would be useful to know whether you used a single external streamer for each DAC or a CD transport. Also, whether you used a single type of connection, such as USB or something else. Thank you.

Since the music consisted of approximately 35-second snippets from six different songs, everything was prerecorded and played in the same order. I believe a single server (although I don’t know the brand or model) supplied the audio via USB, with the connection moved from one DAC to the next. I also don’t know which USB cable was used.

Were there also other dCS DACs in that comparison? And if so, were they equally liked or was there a noteable preference for the Rossini?

No other dCS DACs were included in the showcase; my Rossini was the only dCS product submitted. I would have really liked to have heard a Lina or Bartók in the blind comparison, and I can’t help but wonder how either might have altered my conclusions.
