USB DACs Super Test: PC + DAC = HI-FI (Part 1)

7/8/2013 9:22:04 AM

Adding a digital-to-analogue converter to your computer or laptop produces a very satisfying musical equation. The choice is now wide and the quality high, and there’s one to suit your taste

Whether ripping CDs into various file formats, downloading high-resolution songs, or streaming music from services, your computer is fast becoming the main hub for your music system. But let’s face it: a computer’s sound quality isn’t really up to scratch. So what’s the best way to elevate your computer-based music into the realms of hi-fi? Simple: add a DAC. A digital-to-analogue converter with a USB connection is all you need to bridge the gap between your computer and stereo equipment (or headphones) to create a system that’s convenient, versatile and, most importantly, sounds fantastic.

We’ve put together a tantalizing selection of nine DACs, all from established brands and all vying for that prime spot next to your computer. Turn the page to see which DAC suits your hi-fi needs and budget best.

Audioquest DragonFly: $340

You’ll be forgiven for your double-take at the star rating. Our most recent 2012 DAC Product of the Year down to four stars already? Yep, we were surprised too. But with plenty more portable USB DACs popping up in what was once a very niche market, the competition is hitting up even more – and that makes us very excited indeed.

When the Audioquest DragonFly first arrived at our offices, it was the first of its kind: a DAC and headphone amplifier all tucked into the size and shape of a USB memory stick. All you have to do is plug it into the USB port of your computer, slot a pair of headphones into the DragonFly’s sole 3.5mm output, and voila! – You’ve transformed your computer into a full Hi-Fi system.

A paragon of great design and portability, the DragonFly also offers real sonic bite

The design of the DragonFly makes a long-lasting impression as well: the matte-black finish is smooth and the DAC itself has good weight, lending it the classy feel of a high-quality product. The neatest feature is the DragonFly logo embedded in the stick – it lights up with different colors depending on the type of file being played: 44.1 kHz (green), 48 kHz (blue), 88.2 kHz (amber), and 96 kHz (magenta). The asynchronous USB DAC can handle files up to the full 24-bit/192kHz, but they are down sampled to 96 kHz first.

It’s elegant, yes, but it’s not just a pretty face: the DragonFly charges along with a bold and energetic attitude, full of rich, clear detail in an open soundstage. There’s fast and agile timing, along with a good deal of muscle in the lower frequencies. There’s also a good sense of depth that allows you to engage with the music, and vocals are delivered with plenty of emotion.

Attack and energy

If you’re looking for a DAC that favors attack and aggression, the DragonFly is ideal: it has an endless supply of energy that ensures a fast, punchy sound – albeit with a touch of hardness to the overall presentation. Play Rage against the Machine’s killing in the Name and you get the full impact of the anger and intensity behind Zach de la Rocha’s vocals and the heavy guitar riffs.

Despite all that, the DragonFly no longer has the monopoly on its particular brand of portable USB DAC: new rivals in the shape of the HRT micro-Streamer and Meridian Explorer have emerged, and their impact can be seen in the DragonFly’s new star rating.

Play a WAV recording of Oasis’s Wonderwall, and both the HRT and Meridian DACs manage to uncover another layer of subtle detail, that gives more depth and space than the DragonFly(which seems just a bit too hard and insistent in comparison).

Don’t get us wrong – the DragonFly’s attacking sound is exciting, but it may not suit long periods of listening as the hardness can start to grate.

New rivals may have ousted the DragonFly from its throne in terms of outright sonic performance, but there’s no escaping the fact that it’s still an extremely attractive piece of kit to own. Its super-portable, has a great design, and delivers a solid and exciting sound: the DragonFly still has lots of appeal.

Rating: 4/5

For: Great design and build; highly portable; bold dynamics; agile timing; clear detail

Against: The slightly hard edge to the sound can become tiring; not the last word in subtlety

Verdict: We still love this little device, but newer rivals have pushed it off top spot
