Our take on the brand
Look inside the brand
Our interview with the brand
What are two key technological innovations or strong opinions that differ you from other brands?
We do not use any standard DAC chip solution from the open market, but rather developed our own proprietary conversion algorithms and programmed them into general FPGA processors that are field upgradeable. In other words, every improvement or change in algorithms can be downloaded from our website and loaded into our products, all by the end user. More details are here.
For one of the most critical components in any DAC we, again, are not using any standard technology, but rather developed a very unique and proprietary algorithm that takes into account the very sensitive properties of our human hearing system and they way it perceives clock jitter. More details here.
When we were part of the DSD creation team at Sony we were tasked with a very challenging project: the definition of a high speed digital communication protocol that would support any PCM and DSD format (i.e. sample rate). This link should be able to transmit any audio data from any source to a DAC. The solution I came up with is based on a high speed fiber optic data link as it is used in super high speed data links where secure data recovery at the receiver is crucial. While the speed of transmitting audio data is well and way below the capability of such fiber optic links I still chose this physical link because of its superb data and clock integrity / stability. In addition the fiber optic media provides a galvanic separation between digital source and core DAC circuitry. This alone already results in an audible improvement. All our products support this link and we call it PLINK. We use it to connect external transports, servers or USB interfaces to our DACs.
What's your approach to customer support?
We see customer support as an opportunity to show to the customer who we are and how much we care. Usually, I answer all inquiries and customer support requests personally, within 24 hours and with as much technical info as possible. While some of our dealers possess good technical know-how and are able to interact with customers on that level directly, other distributors do not provide any technical support. Either way we encourage customers to contact us directly for any help.
I often get feedback from customers that this kind of direct and expert support ultimately convinced them to buy our products. So obviously the way we do it is not standard in our industry.
What are your favorite tracks for showcasing the strength of your products?
There are many excellent recordings that can demonstrate the behavior of our of DACs, but it is mostly a function of the listener's taste in music. For instance, people who do not like classical music do not hear its finesses when played on our equipment etc. For my own personal taste I often use any DSD re-mastered track of Pink Floyd or Roger Waters. This is also because most of these tracks were mastered using my designs and with that they show off specifically the "analog-like" behavior during transients of our DACs and the resulting 3-dimensionality of the sound stage.
What other products pair best with yours?
As a digital "pure-bread" listener I do not use analog sources myself and only our own electronic designs (including amplification) for playback paired with a variety of different loudspeakers from mid-size to professional near-field monitors. The latter are usually more revealing and neutral than most consumer or audiophile speakers, but are only suitable in small studio environments. Over the years I have been working closely with brands such as Hafler (professional speakers), Evolution Acoustics, Stenheim and many speaker manufacturers.

Our take on the brand
Product Strengths
- Detailed, clear, harmonically rich, and musically engaging, ticking all the audiophile boxes
- Retrieves more low-level data, texture, and atmospherics and is smoother, less grainy, and more powerful sounding—hence more transparent and emotionally engaging—than the pre-Apex version
- A solid, heavily engineered unit, built with aerospace-grade machined aluminum panels and acoustic damping
- Can operate as a complete network-connected digital player, streaming from a music store or online sources, via its galvanically isolated RJ45 Ethernet port
Product Considerations
- Considered second from the bottom of the line DAC and can be considered expensive
- Physical appearance looks the same as the 2.0 version, which also looks the same as the original Bartok
- The preamplifier section, with its attenuator, plays more distinctly, with clearer and more prominent highs
- The depth of the soundstage is not particularly exceptional compared to the Rossini series and, above all, with the Vivaldi; the tested player shows everything close, rather than plunging the instruments into the space far behind the speakers
Takeaway: The dCS Bartok Apex delivers a harmonically saturated sound with plenty of color information, including depth. This product could be worth buying if you are looking for a DAC.

Our Summary
Product Strengths
- Startling clarity
- An extraordinarily clear view of the 'reality' of the recording
- Subtlety is exposed, which made listening a fuller, more complex experience
- Sound quality is unmatched in terms of technology, design, build and finish
- A very fluid, massive and somewhat dynamic soundstage
Product Considerations
- The dCS Mosaic app is starting to feel clunky
- Basic display
- Some holes when it comes to features
- Audiophile sound is mostly faint clouds hovering between boxes
- It is wished the streamer had Wi-Fi compatibility, but dCS sees this as compromising on sound quality
Comparisons (according to reviewers)
- Vs Denafrips Terminator Plus—it replaced the Denafrips Terminator Plus
- Vs Chord Dave DAC—the Chord Dave gets very close in sound to the Lina, but the Dave leans a bit leaner and sharper where the dCS Lina is fuller, thicker, smoother with more density
- Vs Weiss 501—the dCS is a smooth sounding DAC indeed, but it is not one of those that sound overly smooth, the Weiss 501 sounds closest to an in-studio experience, where we get the master tape kind of sound
- Vs HiFi ROSE 150b—the ROSE feels and looks to be built to a similar level (at least the outside), and is gorgeous as well, it's not nearly as refined or together in the DAC department when comparing it to upper echelon products
- Vs dCS Bartok Apex—compared to the Bartók Apex, the Lina's sound (without the Master Clock) had a slightly different textural quality, not coarser or finer grained but as though performers were viewed under a different quality of light, the Lina's light felt slightly more brilliant than remembered with the Apex and maybe 3o cooler
Takeaway: The Lina DAC is a small but very technologically advanced DAC and delivers music with a bonafide life-force behind it. This DAC brings a larger soundstage and bigger sound to the room and is well worth the cost if you have a system that can stand toe to toe with it.

Our take on the brand
Our Summary
Product Strengths
- Known for analog-like qualities in dealing with transcoding zeros and ones
- Conveys low-level musical complexity and subtle spatial nuances that other DACs have difficulty with
- Produces voices that expand in three dimensions with a refreshing sense of presence, reminiscent of vinyl reproduction
- Returns energy to the music, instead of taking it away
- Reproduces details and anchor points with refreshing vividness, presenting the actuality with the least fragmentation of the sound image
Product Considerations
- A single-ended into a balanced pre configuration caused occasional static, making image difficult to discern during those moments
- Clarity could be improved on very complex choirs and instruments, and more separation would also be beneficial
- The attack on drums is slightly slow—perhaps medium paced—compared to some DACs
Comparisons (according to reviewers)
- Compared to CH Precision C1.2 DAC, the DAC III is more emotionally involving, while the CH Precision sounds markedly cooler, flatter, and more emotionally restrained
- Compared to aqua acoustic quality Formula xHD, the Formula xHD retrieves detail, bass precision, articulation, and transparency better, while the DAC III is airier, more fluid, and more refined
- Compared to Holo Audio May, the attack on drums is slightly slow—perhaps medium paced—and behind the Holo Audio May as well
Takeaway: The SW1X Audio Design DAC III Balanced has a musicality that makes it worth considering. It expresses music in a way that is closer to analog, with a natural transparency and higher degree of contrast.
Video review
Our take on the brand
