Which means you might think twice about whether it’s suitable for your ‘portable’ purposes. Its dimensions (30 x 66 x 129mm) and weight (240g) mean it’s far from big or heavy in and of itself, but there’s no denying it’s bigger and heavier than almost any smartphone you care to mention. Much like the Chord Mojo we’ve already discussed, the EarMen TR-Amp is a cuspy product.
Which, when you have another glance at that price-tag, is probably just as well. In fact, the iFi iDSD Diablo could well be all the DAC you’ll ever need. No recording is too dense, too complex or too tricky to wrong-foot it. It’s controlled, it’s insightful, it’s tonally impeccable and, above all else, it’s musical. Its powers of analysis - the way it peers deep into a recording and returns with every scrap of information - are staggering, and it has the sort of dynamic headroom that can make the distance between ‘very quiet’ and ‘very loud’ very wide indeed.

The EarMen Sparrow, then, is further proof - as if any were really needed - that it's not the size of your DAC that counts. heck, even something as fundamental as volume gets a boost. Detail levels, the definition of the soundstage, the extension and control of bass sounds. Even the cables it’s supplied with look and feel quite expensively braided.īest of all though, is the fact the difference the Sparrow can make to your smartphone-derived sound is out of all proportion to its, um, proportions. So good luck trying to find audio files or headphones it’s not compatible with.Īnd even though it’s hard to make a product of these dimensions seem like value for money, the glass-and-steel construction make it feel good too. It can handle most digital file types, from PCM and DSD to DXD and MQA, and it’s got both 3.5mm unbalanced and 2.5mm balanced headphone outputs.
