The setup is absurdly simple: attach a micro-USB cable to the corresponding slot on the DacMagic XS and plug the cable’s other end into a USB socket on the computer. Plug the mini-jack cable connected to the headphones into the corresponding (gold plated) headphone socket that’s at the DacMagic XS’ other end. Then select the device from your computer’s output settings and that’s it (on a Mac that meant going to the Sound Output tab in System Preferences). The only active controls on this sleek and compact (matchbox sized) device are a set of buttons for volume up/down — since the xxx might be placed in an awkward place that’s difficult to reach, the most efficient route is to press the volume up button to near-maximum and then rely on the computer’s volume controls (in most cases, located on the keyboard).
The DacMagic XS gives you the choice of two levels of audio resolutions: USB 1.0 mode covers 16/24-bit, 44.1kHz, 48kHz, 88.2kHz, 96kHz, while USB 2.0 mode covers 16/24-bit, 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz — obviously if the system can handle and provide higher resolution audio files, then use USB 2.0. Pressing the volume buttons in a predetermined manner will switch between modes, and a small LED will indicate what’s what by changing colors (a pink flash for 2.0 for example). The tiny manual that’s included is worth poring over once so as to get these facts into the mind.
Now in the real world, measuring sound waves and taking frequency readings don’t wash: it’s about how the audio sounds when heard through the DacMagic XS as compared to when not. Obviously a standard has to be applied, and in this case that’s taken care of through the rock-solid audio reproduction that’s been a mainstay of my Sennheiser over-the-ear headphones for more years than I can count now. And I won’t attempt to “see” whether poor quality, low resolution MP3 files sound “better” — GIGO rules so everything I’m playing is lossless FLAC. That doesn’t mean I won’t pop into a YouTube audio track or a game, but starting with quality audio files should make the difference between hearing what the DacMagic XS can do when given its lead.
2 weeks has now gone by and I can say with some appreciation that the DacMagic XS is well worth its $199.99 price tag. Every audio file — be it pop, rock or classical — benefited from having it doing the heavy lifting of the audio stream. The comparison of sound from using it and then replaying the audio without at times was startling — especially when classical was being listened to. Think of it as a densely layered forest that has 5 or 6 or more areas to explore aurally, one behind the other. Noise, jitter and distortion get a serious smack on the side of the head. Then consider that without the DacMagic XS in place, instead of being able to hear all of them interwoven with the other, the sound becomes something akin to poking a sharp stick in that penetrates a few of the layers and then gives up. That I had to return the device afterwards was personally annoying. Especially since it was making my watching Archer (FX animated show) so much more effective, since I could better hear the quickly-passing one-liners and other comments that typify its humor. The level of clarity that this DAC presents is really something for such a small device. Bottom line: The DacMagic XS performs a “simple” task that requires a high-level of sophisticated audio circuitry. It’s not like you need what it can do, because you don’t know what you’re missing until you have it in hand to listen with. Then you don’t want it going anywhere from your computer ever again.
