The DC-05 also claims “Time Domain Jitter Eliminator and HyperStream III Architecture” to reduce signal noise and distortion, and I did find it to be extremely quiet and hiss-free. Finally, and most critically, it has substantially above-average driving power and pairs much better with planars and lower-efficiency IEMs than its cheaper rivals. It does run warm, but doesn’t seem to be a battery hog.

Said driving power really defines the DC-05’s sonic character—it has a rich, slightly warm tone which deepens the low end and makes drums and percussion sound larger-than-life, all of which has the effect of enlivening poorer recordings and lower-quality files.

High end is a bit smoothed over and some high-level details are missing; on better recordings, the DC-05 can sound a bit blunt, albeit never shrill or peaky.  The dirt-cheap Conexant CX31993 actually sounds more transparent and less colored than the DC-05, but significantly trails the DC-05’s dynamic slam and bass control.

Fairly compared to a price peer like the ($70) Hidisz S-3 (which on its own terms is quite energetic and bassy), the DC-05 sounds deeper, louder and fuller, while the more analog-sounding S-3 is truer-to-source and presents more high-end resolution.  The S-3 also places more air between instruments. I preferred the brawnier DC-05 for rock and the more nuanced S-3 for jazz and acoustic fare.

Moving up the foodchain to the $110 Cozoy Takt-C gives you a more neutral presentation, with much less bass boost and more treble detail, although the DC-05 worked better and sounded less reserved and more impactful with less efficient (>150 Ohm) buds and cans.

Ultimately, I probably wouldn’t be content with the DC-05 as my only dongle, as less adrenalized pieces pair better with certain sources and genres. That said, it is a step up from entry-level and the point at which diminishing returns starts to kick in. Recommended.

Even allowing for some recency bias, the Xumee immediately registers as a real find, with a full-bodied, crisp attack, good driving power and notable dynamics and bass impact. It synergized surprisingly well with my new crush, the difficult-to-drive 7Hz Timeless, which sounded louder and more  expansive with the Xumee than they did unamped.

Likewise, the 60 oHm Koss KSC75 took on a palpable physicality with the Xumee, sounding bassier and more like full-sized cans. The Xumee did run out of steam on my 250 ohm Beyer DT 990, which had sufficient volume but sounded wimpy and bloomy at the low end.

On more sensitive (<32 ohm) IEMs, the ($13) Conexant CX31993 sounded more transparent and presented more high end detail, but lacked the energy and low end control of the Xumee, while my current budget fave,  the $23 Meizu Master, matched the Xumee for output power and impact, but sounded a bit coarse in comparison, with a bit of graininess at the high end.  

Moving up the food chain to the $70 Hidisz S3, however, demonstrated the Xumee’s budget roots—while the Xumee played louder and had more low-end presence, the S3 was clearly the more refined, with more lifelike, less artificially bright timbre and a smoother (though still quite detailed) high end. However, the Xumee was a better match for brighter IEMs like the Blon A8 and Whizzer Kylin HD03D than the $75 Audirect Atom 2. So much for price/performace.

While my personal donglequest will undoubtedly continue, I’d venture that among the current flood of barely-distinguishable cheap dacs the Xumee is likely the best.  I’m glad I bought it instead of that fifth of Jim Beam.

On a somewhat related note, I also sampled the surprisingly cheap ($9) Apple USB-C audio adapter, which Jürgen has reviewed favorably here. Simply stated, the Apple does not play well with any Android or Fire devices, producing very low volume and a rolled-off high end.  

The lightning version, OTOH, works perfectly well with my wife’s iPhone, with more than adequate output and a very clean, uncolored presentation. I’m not sure what Apple’s reasoning is here, but if it don’t work it ain’t a bargain.

Xumee

The post Xumee USB-C DAC Dongle Review – A View From The Cheap Seats appeared first on Audio Reviews.

The dongle itself seems well-made and is quite a purty thing, with silver wire and nicely-engraved connectors. The cx31993 is strictly plug and play (no drivers needed) and its advertised 96/384kHz sampling is legit. It runs cool and doesn’t hog a lot of battery.

The cx31993 presents a lean, neutral-to-slightly-bright tonality without audible coloration or grain; background is very quiet and presentation is open and airy.  Connected to my LG V50, the cx31993 paired well with my more efficient IEMs, noticeably improving the resolution and placing more space between the performers.

Combining it with the $5 KZ EDR1 was sublime. The cx31993 was also a big improvement over the flat, colorless stock soundcards in my Kindle Fire and Dell laptop.  

However, it became readily apparent that the 31993 lacks the output power to effectively drive less efficient buds and cans (such as 150 Ohm Beyerdynamics); it particularly struggled to control the low end on more challenging loads.  

Even the Blon A8 whose 32 Ohm impedance doesn’t seem daunting, seemed to lose composure and sounded somewhat flabby and bass-shy when paired with the 31993.

Unless you’re really budget-impaired, the $23 Meze Master HiFi is the better buy, with more power and overall presence, although I actually thought the cx31993 was a tad cleaner and more transparent (though less energetic) than the $42 Tempotec Sonata HD.

This isn’t the megacheap miracle its proponents claim and probably won’t work as your daily driver. It is, however,  a useful upgrade on to PCs and other devices and ultimately earns a place in my ever-expanding collection of dongles
