What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

5
Reviews
Nagra Audio, a Swiss brand with roots in professional recording and film (including two Oscars for soundtracks), brings watchmaking-level precision to their hifi equipment through extensive in-house manufacturing of components like transformers. Their HD Preamp and Classic DAC showcase unique technologies, including virtual battery power supplies and PCM-to-DSD conversion, while their commitment to quality is demonstrated by rejecting over half of their tested valves to maintain exceptional standards.
Expand Details
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.

Expand Details
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.

SW1X
DAC III (Balanced)
15950
/
Released
2022
The Balanced version of the DAC III is a non-compromise valve output stage design DAC III, equipped with Signal Output Transfromers (OPTs), a smaller brother to the DAC IV and DHT output stage based DAC V. The step up in transparency of the Balanced over the SE version is provided by a signal output transformer de-coupled EL84 power pentode (triode connected) tube output stage driven by the mighty 6N6P double triode.
SW1X Audio Design creates DACs that use a non-oversampling approach and vintage TDA1541 chips with tube output stages, avoiding digital filtering to maintain a more natural, analog-like sound. Their products feature separate power supply chassis designs and harmonically matched vintage components, including directly heated triode tubes and AB resistors, which are carefully selected for their distinctive sonic qualities.
Expand Details
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.
