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
- The d1-triunity DAC is praised for its ability to reflect the core characteristics of music with purism and vibrancy
- The 'unity' architecture provides more presence, more contrast between the timbres and sizes of each instrument, more clarity, and at the same time more body and more dynamics—making the sound more realistic and natural
- Offers a richer, sweeter, fuller sound and a more spacious presentation compared to the d1-unity
- Achieves dynamic power, low-frequency depth, and punch with a skillfully engineered Class-A output stage providing double the voltage
- Transmits detail and nuance without sounding etched or bright, and provides great tonality, especially with acoustic instruments
Product Considerations
- The chassis is constructed from folded steel and the rear panel is of a thin gauge, which makes the external construction less substantial than some rivals
- Maximum resolution of 24-bit/192 kHz without the optional DSD module might be a limitation
Comparisons (according to reviewers)
- The d1-triunity brings improvements that make music sound more vibrant and alive, while offering a finer-grained view compared to the Totaldac d1-unity
- The d1-triunity provides universal compatibility in terms of voltage output, and advances the sonic performance aspect compared to the Totaldac d1-direct
Takeaway: The d1-triunity is an impressive DAC that effortlessly handles music and makes it emotion-tugging with crystallizing quality. It offers remarkable musical insight without sacrificing speed and clarity, making it a worthwhile addition to any high-end audio system.
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.

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.

D1-core
- Positioning: The entry-level model in the Totaldac lineup.
- Description: Offers a natural and musical sound, using the same ladder resistors and FPGA as higher-end models, making it a great performer for its price. It is ideal for those with a smaller budget who still want high-quality sound, but it lacks some of the advanced features and components found in more expensive models like the D1-unity.
D1-unity
- Positioning: A mid-range model that introduces the new "unity" DAC architecture.
- Description: Enhances sound presence and clarity with its upgraded clock distribution and lower jitter, making it suitable for users seeking a more realistic and dynamic sound. Compared to the D1-core, it offers improved component quality and a new output stage.
D1-biunity
- Positioning: A step above the D1-unity, featuring dual R2R ladders per channel.
- Description: Provides a lower noise floor and more accurate instrument scale, making it perfect for audiophiles who prioritize sound detail and precision. It builds on the D1-unity's architecture with additional components.
D1-triunity
- Positioning: A high-end model with three R2R ladders per channel.
- Description: Delivers exceptional detail and tonal precision, ideal for users who demand the utmost in digital playback quality. It surpasses the D1-biunity by further reducing noise and enhancing sound realism.
D1-sublime
- Positioning: The flagship model, incorporating multiple components and accessories for ultimate performance.
- Description: Offers outstanding 3D sound and body, making it the top choice for those who want the best audio experience possible. It includes monobloc DACs and a reclocker, setting it apart from the D1-triunity with its comprehensive setup.

SW1X
DAC IV
25275
/
Released
2024
DAC IV is a further development in musical scale & refinement of the already magical sounding DAC III Balanced powered by Power Output Valves and Directly Heated Diodes (DHD) in the power supply. The DHD Valve power supplies are 2 x choke filtered and quasi dual mono in design. Accomodating everything in one chassis without interference of magnetic fields proved to be a real challenge but having everything housed in one chassis with much shorter signal paths turned out to be very rewarding in the end.
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.

Our Summary
Product Strengths
- Notable focus and density to the midrange that is unparalleled compared to other DACs
- Exceeding naturalness and deep detail
- Top end is smooth, and the low end is present and provides a substantial foundation
- More precise, revealing, and dynamic presentation
Product Considerations
- The review unit lacked a USB input, only offering AES/EBU and S/PDIF over Coax as inputs
- Might not suit audiophiles who prize dry, bright, or hard-sounding digital audio
Comparisons (according to reviewers)
- Compared to solid-state DACs, the SW1X DAC IV Special has unparalleled focus and immediacy of dynamics, especially in the midrange
- Compared to the SW1X DAC V—the DAC IV has a more precise, revealing, and dynamic presentation
Takeaway: The SW1X DAC IV Special could be the answer if one wants to feel more emotionally connected to their music and escape the constant analysis of typical audiophile listening. It's designed to provide a musically engaging experience.
