Video review
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 take on the brand
Product Strengths
- Natural and warm sound with a big and smooth body to the music, almost like listening to vinyl but even better
- Delivers a life-size scale to the instruments and vocals, providing a very realistic and immersive experience
- Details presented are life-size and realistic with beautiful timbre, emerging from top to bottom of the range
- Creates intensely black backgrounds and has a natural musical way of delivering the music
- Makes even lower quality streaming sound beautiful, improving even bad recordings
Product Considerations
- The retail price is very high, making it primarily accessible to the upper 1% of consumers
- Not about 'bite', 'crispness', or 'impact' in the traditional digital audio sense, so those seeking those qualities may prefer other DACs
- The Tube DAC has a beautiful preamp section, but it doesn't provide additional analog inputs
- It's crucial to pair it with a high-quality streamer to unleash its full potential; using a lower-end streamer could bottleneck its performance
Comparisons (according to reviewers)
- Vs Holo Audio May KTE: The Nagra Tube DAC sounds even more natural and removes digital traces present in the May KTE
- Vs Chord DAVE: The Nagra Tube DAC is more ethereal and holistic, while the Chord Dave is more detailed up top and excitable
- Vs Weiss 501 MKII: The Weiss MKII is excellent—but doesn't quite reach the heights of the Nagra
- Vs Nagra Classic DAC: The Tube DAC's sound stage became almost holographic and the sound even smoother, richer, cleaner—and clearer
- Vs EverSolo A10: The EverSolo is great with the Nagra when used as a streamer, it brings a beefy yet clear and beautiful spatial sound, but loses out to some excitement and depth to the HiFi ROSE
- Vs WiiM Ultra: The DAC was being a little bit choked as all of the magic was not audible, as it was with the HiFi ROSE
Takeaway: The Nagra Tube DAC is considered by many to be one of the best DACs available, providing a beautiful, lifelike, and engaging listening experience that is a special end-game product. It connects the listener emotionally with every song, making music sound as good as it can.

Our take on the brand
What competes at this price?
Compatible with all digital audio formats
Supports hi-res streaming from Roon, TIDAL, Qobuz, Spotify, Deezer, AirPlay & more
Features our renowned dCS Ring DAC TM and Digital Processing Platform
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.

- The signal level out of the balanced XLR sockets (2.1V) is the same as the single-ended connections, rather than double, as it usually is
- Some found the new white logo lighting (instead of the traditional green) to be a negative
- There is not enough space under the sharp cooling fins for fingers
Comparisons (according to reviewers)
- Vs NSC 222: The NSS 333 justifies its price premium with even better sound quality
- Vs Naim ND 555/555 PS DR: The Naim NSS 333 delivers a significant chunk of the ND555/555 PS DR's performance at a fraction of the price
- Vs Moon 681: The NSS 333 delivers admirable precision and stability in the way it places instruments and sounds, though the Moon 681 produces more in terms of soundstage width
- Vs Naim NDX: The NSS 333 offers significantly more air and space in the recording, a greater sense of detail, and a notably natural and unforced delivery
- Vs NDX2: The new player sounds better and closes the gap with the flagship ND555 player, at least when the high-end machine is used in its basic single power supply configuration
Takeaway: The Naim NSS 333 is a musically satisfying music streamer with excellent build quality and the ability to convey emotion. It combines detailed, richer sound with a slick and user-friendly experience.

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
Our Summary
Product Strengths
- Surprisingly technical, with resolution on par or better than anything else heard at its price point
- Conveys the time of music extremely well, notably with exceptional leading-edge portrayal and high resolution/micro dynamics
- Offers excellent timbre
- The internal streamer presented better clarity in the bass
Product Considerations
- With signals above PCM 24 bits and 192 kHz, the converter down-samples the signals
- DSD signal is converted internally to a PCM signal, since the R2R resistor ladder is a 24-bit circuit
- Treble compensation may be needed for optimal sound, or to lower excessive treble energy
Comparisons (according to reviewers)
- Versus Totaldac d1-tube DAC/Streamer, the d1-unity offers greater clarity, voice, and impact, providing a more fully resolved picture
- Versus Mola Mola Tambaqui DAC, the d1-unity offers more body, tone, and texture, whereas the Mola Mola emphasizes upper frequencies a bit more
- Matches the resolution and dynamic presentation of the Chord Dave
- The internal streamer is marginally better than the Sonore Optical Rendu
Takeaway: The d1-unity is a good option for those seeking an engaging and high-resolution digital source. It is especially suited for listeners who appreciate a physical and vibrant presentation of music.
