What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- Natural-sounding converter, almost vinyl-and-valve like
- Resolves a lot of spatial information, throwing out a soundstage that is big and muscular, but also deft and subtle
- Extraordinarily detailed
Product Considerations
- The online manual for the streamer is complex
- The dynamic range isn't quite as remarkable as its naturalness, and this comes across as a lack of scale and solidity
- Playing files from a thumb drive slotted into the converter itself is the best sounding way, which is more fiddly
- Not a universally applicable recommendation
Takeaway: The Totaldac d1-core is a great DAC for audiophiles who want a natural and detailed sound. It's especially good for those who appreciate the sound of vinyl and are willing to put in some effort to get the best possible sound quality.

Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- Totaldac's DACs employ a discrete R2R resistor ladder design, utilizing meticulously chosen, high-precision Vishay Bulk Metal Foil resistors (typically 100+ per channel), rather than integrated DAC chips, for its digital-to-analog conversion.
- The brand stands out for its highly natural and "analogue-like" sound, often described as possessing tonal density, harmonic richness, and a realistic presence that some find lacking in many other digital sources.
- Totaldac products offer a unique level of customizability, allowing users to select options such as DSD playback, bass boost, and even the material of the front panel to tailor the sound to their preferences.
- They have designed their digital volume control to minimize negative impact, offering the flexibility to connect directly to a power amplifier, but recommend the use of an external preamplifier.

Our take on the brand
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.
