Review: Cambridge Audio DacMagic XS Portable DAC/Headphone Amp

Ever since trying out professional quality headphones with a digital audio converter (DAC) and headphone amp, it’s hard for me to listen to music without them. Unfortunately, the amplifiers in most computers are woefully underpowered – and most headphones are designed to operate at a low impedance to make up for this shortfall. But most headphones prefer to be driven with more power than most consumer electronics can muster. Additionally, the DACs built into most computers are sub-par in my experience.

I recently had the opportunity to test out a combination DAC/headphone amp from Cambridge Audio called the DacMagic XS.

This pocket-sized device is easy to tote around wherever you go, and provides a significant boost to headphone sound quality on your PC or Mac. Measuring just 2.1″(h) x 1.2″ (w) x 0.4″(d), and weighing only 3.5 oz., it’s definitely teensier than I expected it to be.

The DacMagic XS plugs into your computer’s USB port, and bypasses its internal audio output. Its 24-bit ESS9023 DAC is capable of handling audio bit rates from 44.1 to 192kHz, and its amp puts out up to 150mW of power. It’ll work with headphones with impedances as low as 12 Ohms, but will also work with higher impedance studio quality ‘phones. In my case, I tested the unit primarily with my current favorite cans, Beyer Dynamic’s DT990 Pro 250Ohm headphones.

To test the DacMagic XS, I first connected my headphones to the headphone jack on my 2011 iMac, and cranked up some high-quality digital tracks from iTunes and some medium quality tracks from Pandora. I was pleasantly surprised to find that the miniscule box pushed out nearly as much volume as my much larger and less portable FiiO system.

Thanks to it’s almost non-existent 0.004% total harmonic distortion, sounds are clean and crisp at any volume level. I definitely found sound to have crisper highs and much clearer lows when listening via the DacMagic than via the iMac’s built-in headphone jack.  One of my favorite audio test tracks is Donald Fagen’s 1980s jazz fusion classic New Frontier, because it’s got huge dynamic range both in instrumentation and vocals, and most cheaper sound systems fail to extract the brilliance of the track. On this track, I found audio from the DacMagic XS to be significantly cleaner than the computer’s built-in DAC and amp. It’s especially deft at producing clean sound at lower volumes which cheap amps don’t do well.

To mix things up, I also tried out my trusty old iPhone earbuds with and without the DacMagic XS. Connected directly to my computer, sound was harsh – almost unlistenable at higher volumes. With the XS in place, sound is more evenly rounded and not as harsh – though it can’t do much to aid the lack of low end in earbuds. Still, sound was decidedly better with the XS connected.

For my final test, I tried tracks on my Marshall Monitor headphones, which offer very even and natural sound but at a low impedance. Sound has a tendency to be a bit muddy and lacking in definition plugged right into the iMac, but with the DacMagic connected, sound is wonderfully rich and well balanced. Again, a clear win for the little guy.

There’s really not much to dislike about the DacMagic XS. Certainly it’s a winner in terms of sound quality, size and portability. You can really take it anywhere. I have a couple of gripes, but they’re fairly minor. First, when connected to my iMac, I could no longer use the keyboard volume controls, and could only use the face buttons on the DacMagic. For comparison, this isn’t a problem with my FiiO DAC/amp. And while the tiny MicroUSB/USB cable is good for many situations, I think they should have included either a longer cable or a coiled version, in the event you don’t want the DacMagic dangling from the back of your computer and want it to sit flat on your desktop. Plus, a longer cable would be good if you’re using a workstation and not a laptop or all-in-one. Still these issues are very small, and the DacMagic XS does exactly what it promises – dramatically improve sound quality in a tiny package.

The DacMagic XS is available from Amazon for $189(USD).

Cambridge Audio Minx Xi Review: Give All Your Digital Audio A Big Upgrade – For A Price

minx-xi-main

UK-based Cambridge Audio has long made very well-regarded high-end audio equipment, but recently that’s a market that has changed considerably, thanks to the advent of digital audio and online streaming services. The company has changed, too, and one example of that change is the new Minx Xi all-in one streaming device, which adds to Cambridge Audio’s growing family of digital-focused Minx products.

Basics

  • Wi-Fi & Ethernet
  • 2x USB 2.0
  • Toslink Optical audio in
  • Digital S/PIDF input
  • BT100 Bluetooth receiver included
  • 2x RCA inputs
  • 3.5mm audio input
  • Headphone out
  • 2x speaker out
  • Subwoofer out
  • Built-in Dual Wolfson WM8728 DAC
  • MSRP: £600, $899 in the U.S.
  • Product info page

Pros

  • Excellent sound
  • DAC works wonders for Bluetooth or when connected via optical to a Mac

Cons

  • Wi-Fi but no AirPlay support

Design

Cambridge’s Minx Xi is not dramatically different from what you might expect of any home theatre or hi-fi stereo component device; it’s essentially a black box (or white, if you choose that option) with ample venting on top, a face with knobs and buttons, and a rear with the majority of inputs and outputs. But small design flourishes make this a very attractive, and decidedly modern piece of stereo kit.

  1. minx-xi-back

  2. minx-xi-fr-lft

  3. minx-xi-front-rgt

  4. minx-xi-main

  5. minx-xi-front-top

The rounded rectangle border that surrounds the face is a nice touch, and frames the tall and wide display nicely. The display itself provides just enough information for easy navigation, without overwhelming or drawing the eye unduly. The low-res, basic LCD readout is a little behind the times in a market flooded with OLED panels, but it’s actually pretty refreshing in its retro appeal, and still gets the job done just as effectively as more advanced screens.

The Minx Xi case houses a lot of complicated internals, but it’s still relatively compact, and would look at home either in a stereo cabinet or on its own atop a dresser, bookshelf or cupboard. Paired with Cambridge Audio’s new Aero 2 bookshelf speakers, it makes a good-looking and minimalist setup that’s still capable of putting out impressive enough sound even for watching the occasional Hollywood blockbuster.

Features

Movies are now where the Minx Xi shines, however. Instead, it’s at its most impressive when it’s working with streaming audio, an area that’s always a challenge when it comes to sound quality. The Minx Xi connects direct to your network via Wi-Fi or Ethernet, and can stream thousands of Internet radio stations directly, access BBC’s iPlayer feeds, subscribe to podcasts and more – without the need for a computer or mobile device for playback.

The Minx Xi does a great job of making even, for example, the 128kbps BBC Radio 4 stream sound excellent, with terrific channel division and a natural rendering of voice and music. If you’ve been listening on computer speakers or even a very capable standalone radio, you’ll probably actually be amazed that what comes through the Minx Xi is the same thing as what you’re used to listening to, the difference is that marked.

Subscribing to podcasts on the Minx Xi is as simple as registering your unit via the web and inputting RSS feeds via that dashboard. This provides you direct access to the latest episodes, and again, its ability to really highlight high-quality voice recording comes through.

The Bluetooth adapter included is external, but it doesn’t cost any extra, and it works tremendously well. There’s generally a big step down in quality when you’re listening to anything streaming via Bluetooth, even though it’s gotten a lot better over time. With Cambridge’s BT100 and the Minx Xi’s special Bluetooth DAC capabilities, performance of A2DP streams get a big boost.

Performance

Just to expand on what I already mentioned above, the Bluetooth streaming powers of the Minx Xi make it so that streaming from your mobile device and listening through headphones is in some cases arguably better than listening to the stream on the device itself. It really is that good. That said, it leaves me wishing even more that Cambridge had included AirPlay functionality on the Minx Xi, since Apple’s Wi-Fi audio streaming protocol offers better performance than Bluetooth to begin with.

Performance for streamed connections is excellent, as mentioned, with 802.11n support and no drop-outs for streams during my usage. Connected to my Mac as a DAC, and used in tandem with both the Aero 2 speakers and my Sennheiser HD 598 headphones, the Minx Xi really starts to show off its magic abilities in terms of boosting audio that you might not even have realized could be improved to begin with.

With both locally resident files, and streaming services like Rdio, the Minx Xi delivers noticeable improvements in quality to attached audio output devices, versus having that same hardware simply plugged directly into the Mac. There’s significant improvement in sound separation and clarity on all files and streams, in my testing experience.

Bottom Line

The Cambridge Minx Xi isn’t an impulse purchase for most at £600 ($899 MSRP in the U.S.), but it’s a big step up in terms of the audio quality not only for Internet radio and service streams, and also for connected computers and devices. The service library is a little limited for my liking (Pandora and Rhapsody, but no Rdio/Spotify!), and I’d love AirPlay, but Cambridge Audio does say that firmware updates will be pushed out regularly, and support for those kinds of things could follow.

That fact that it improves any source dramatically with a built-in DAC that would be expensive on its own, and also operates as a very capable and fairly comprehensive audio streaming box in and of itself, makes this a very desirable piece of kit for anyone looking to take their digital listening habits to the next level.

V-moda unveils Vamp Verza: a dockable, device-agnostic headphone amp and DAC for mobile audiophiles (update: video)

Vmoda unveils Vamp Verza a dockable, device-agnostic headphone amp and DAC for mobile audiophiles

Last we heard from V-moda, the company was appealing to audiophile sensibilities with its $300 Crossfade M-100 portable headphones. Continuing in that respect, today it’s officially unveiling the Vamp Verza as a followup to last summer’s $650 iPhone 4/4S-purposed Vamp spy tool headphone amp, DAC & case combo. The aluminum-clad Verza is a device-agnostic solution that uses a sliding dock system with special $100 Metallo cases to give any supported devices a similar all-in-one feel to the original.

At launch, a GS III case is available, with an iPhone 5 model a few weeks out — the company is aiming to get GS IV and Note II cases out next. The unit’s 150mW x 2 amplifier will bypass your iDevice’s audio output via a USB port on its bottom, while an adjacent microUSB port can take advantage of the external sound card profile found in Android Jelly Bean. V-moda notes the microUSB port acts like a traditional USB audio device, so it’ll work with mostly any device. As you might guess, both ports have their own specific DACs routing audio at different power levels to its op-amp.

Meridian Explorer combines headphone amp, portable DAC and $299 price tag

Meridian Explorer combines headphone amp and portable DAC with $299 price tag

Feel that? If you’re an audio purist, the sensation of your wallet tingling is probably a familiar experience. This time, you have Meridian to thank, which is aiming to help you get the most from your nice headphones. The company just debuted the Explorer: a portable, USB-powered DAC and headphone amplifier that’s priced at $299. Like all external DACs, the unit promises better sound quality than typical onboard solutions can deliver, and as a high-end touch, the Explorer offers asynchronous USB audio for greater timing precision and reduced jitter. Alongside the 3.5mm amplified headphone output, you’ll also find another 3.5mm jack that supports both analog and mini Toslink connections. Each Explorer is built in the UK and measures approximately 4.0 x 1.25 x 0.7 inches. Perhaps most importantly, though, its design doesn’t reek of something that was cobbled together in the garage.

Gertboard extender for Raspberry Pi ships to advanced tinkerers

Gertboard extender for Raspberry Pi ships to advanced tinkerers video

If a seemingly infinitely programmable mini computer like the Raspberry Pi is just too… limiting, we’ve got good news: the Gertboard extender has started shipping. The $48 companion board reaching customers’ doorsteps converts analog to digital and back for Raspberry Pi fans developing home automation, robotics and just about anything else that needs a translation between the computing world and less intelligent objects. The one catch, as you’d sometimes expect from a homebrew project, is the need for some assembly — you’ll have to solder together Gert van Loo’s Arduino-controlled invention on your own. We imagine the DIY crowd won’t mind, though, as long as they can find the fast-selling Gertboard in the first place.

Audioengine D1 Review: An Easy Way to Make AirPlay Sound Great [Lightning Review]

The rise of streaming audio over AirPlay has made it possible to wirelessly play music from your iPhone over your home speakers. But that data comes through as a raw stream of 0s and 1s, and the sound quality isn’t that great. More »

Creative reveals Sound Blaster ZxR, Zx, and Z PCI-Express sound cards, pumps up the volume

Creative reveals Sound Blaster ZxR, Zx, and Z PCIExpress sound cards, pumps up the volume

Along with your first day at school, and (for the boys at least) growing your first peach fuzz mustache, many of you might also never forget your first Sound Blaster soundcard. In the present day (unless you’re blessed with youth) only the Sound Blaster can be enjoyed again, and today Creative introduces its new Z-series. The latest PCI-Express cards use the firm’s Core3D quad-core sound and voice processor and come in three variants: the Sound Blaster ZxR, the Zx and the Z. As you might have guessed, the more letters, the higher up the food chain it is. The flagship ZxR ($249.99) boasts a 127dB SNR, sockets for swappable Op-Amps, 80mW into 600 ohm headphone pre-amp, plus RCA / optical connectivity (via additional daughter board) and an external “ACM” control module for less fiddling around the back of your machine. You can save yourself $100 with the Zx model, if you don’t want the ZxR’s “DBpro” daughter board, and the Z edition saves a further $50 at the expense of the external controller. Want to dive into the full specifications? Plug in to the PR after the break.

Wolfson confirms the Samsung Galaxy S III uses its audio chip

Wolfson confirms the Samsung Galaxy S III will use its audio chip

The Galaxy S III was widely tipped to possess a Wolfson digital-to-analog converter for high quality audio output — a feature not seen in this range since the first Galaxy S. That notion has just been confirmed by the Scottish electronics firm itself, which says its WM1811 Audio Hub has been selected for use in Sammy’s flagship. The chip promises “crystal clear voice call quality” and “enriched audio playback for music and video” thanks to its 24-bit hi-fi DAC, active noise reduction circuits and other wizardry. The GS II, meanwhile, used a Yamaha DAC to convert digital data (e.g. in an mp3 file) into an analog signal that could drive a speaker (for example in your headphones), but even if most people couldn’t hear the difference, audiophiles have insisted they preferred the sound in the older Galaxy. The only question remaining, which the PR after the break does not expand upon, is whether the Wolfson hardware is found in all variants of the new phone. Check out the More Coverage links for further reading.

Update: Francois Simond (aka Supercurio) tweeted us to say that the US variant of the GS III uses Qualcomm’s own WCD9310 for audio, not the Wolfson. Yup, it’s that multi-talented Snapdragon S4 again.
