What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
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.

/
Released
2019
DragonFly Cobalt, the latest and most sophisticated member of the award-winning DragonFly franchise, is a USB DAC (digital-to-analog converter), preamplifier, and headphone amplifier. It bypasses the audio circuitry in laptops, computers, and smartphones to deliver cleaner, clearer, more naturally beautiful music to headphones, powered speakers, or complete audio systems.
AudioQuest is known for its massive library of hifi audio cables and its DBS and ZERO technology to minimize distortion.
Expand Details
Our Summary
Product Strengths
- Provides a simple, effective, and affordable solution to improve sound quality from computers

- The slow roll-off filter in the Cobalt allows for a more natural and balanced sound
- Connectivity options offer usage with a variety of devices
Product Considerations
- Maximum output voltage before clipping drops quite early on as load impedance decreases, due to the output stage's finite current supply
- Maximum PCM sample rate remains 96/24, and DSD is not supported natively
- DragonTail adaptor fits poorly
- Some users reported a firmware bug, on some mobile devices turning volume down to zero results in full blast volume

Cambridge Audio
DacMagic 200M
399
/
Released
2021
Digital audio files can be packed with incredible musical detail, but they need to be converted to analogue first for you to hear it. And how good it sounds will depend on how well the digital audio from your computer, network player or CD is converted. DacMagic 200M's twin ESS DACs decrease crosstalk and improve separation because there's a DAC dedicated to both left and right channels. These fully balanced, optimised, and efficient signal paths reveal previously hidden glittering musical prizes.
Cambridge Audio pioneered the use of toroidal transformers in power amplifiers, a technology now widely adopted by high-end audio companies. The brand stands out for using premium amplification technology across their product range, from Class A/B amplifiers in their wireless earbuds to Hypex Ncore modules in their EVO series, while maintaining accessible price points between their CX and Edge product lines.
Expand Details
Our Summary
Product Strengths
- Rich feature set is its ace card
- Presents a very clean, detailed, and dynamically punchy sound
- Tonal smoothness and expansive soundstage
- Balanced and unbalanced outputs, plus a headphone output
Product Considerations
- Front fascia is a wee bit cluttered
- Lacklustre feel of the volume control
- No remote control
- The headphone output is a useful convenience feature, but it doesn't live up to the unit's performance in other areas
- Auto-shut-off feature turns it off after a little while of not being used
Comparisons (according to reviewers)
- Vs Chord Mojo: Chord edges ahead in performance, delivering even greater subtlety and rhythmic precision, but it can't match the DacMagic 200M's impressive feature versatility
- Vs Schiit Bifrost: Bifrost offers more meat on music's bones, making the DacMagic 200M sound comparatively lighter weight, presenting a skinnier version of the music at hand
- Vs Denafrips ARES II: The DacMagic 200M sounds pale as it does its best to tease out music's kaleidoscope of tone colors
- Vs Audiolab M-DAC+: Rhythmically the DacMagic 200 does a good enough job, it can't compete with the next tier up of DACs costing close to twice its price
- Vs Pro-Ject Pre Box S2 Digital: The sound of the Pro-Ject DAC was not as different from that of the DacMagic
Takeaway: The DacMagic 200M is a feature-rich device with good sound, offering balanced and unbalanced outputs, plus a headphone output. Its versatile feature set makes it a great all-rounder at its price point.
