5 of the best DACs
In case you didn't know, the music on your phone, or your tablet, or your laptop, is stored digitally.
At some point those digital files have to be translated into an analogue signal your speakers, or your headphones, can understand. And that’s where digital-to-analogue converters (DACs) come in.
Everything that plays digital audio has a DAC inside of it. They may sound unglamorous in tech terms (and, God knows, in the case of most external designs, they look it), but they do essential work – they make the difference between your music sounding diabolical or sounding divine.
But not all DACs are created equal. The one inside your laptop is probably hooked up to a headphone jack with cattle-class amplification, which means it'll never do its best work. External DACs are the solution.
(Incidentally, some new devices, such as the LG G2 and Samsung Galaxy Note 3, have internal DACs that support hi-def audio sources up to 24-bit/192kHz, while most devices top out at 16-bit/48kHz. If all this is gobbledegook, check out the jargon-busting boxouts below)
And quality external DACs aren't just for those audiophile 'lossless' FLACs and WAVs that are taking up all of that memory space, either – even the tightwad file sizes on sale at the iTunes store can sound great, and every device, be it an iPhone, iPad, Samsung Galaxy S4, HTC One or a MacBook, can benefit. But only if you’ve got a proper external DAC to take care of business.
Arcam irDAC (£400)

Having a remote control isn’t what makes the Arcam irDAC a great product, but when you’ve got multiple sources connected and have made yourself comfortable, it doesn’t do any harm.
You can connect plenty of sources, too, thanks to the Arcam’s four digital inputs (two optical supporting 24bit/192kHz and two coaxial that top out at 24bit/96kHz), type-B USB and type-A, which will work with your iGadget. And thanks to a load of tech derived from the company’s £2K FMJ D33 DAC, this hefty little aluminium box serves up a pretty compelling sound.
Doesn’t matter if you value rhythm above all else: the Arcam’s speedy and agile. More about the vocals? The irDAC is as detailed and communicative as the singer you’re listening to. Like a bit of complexity? The Arcam’s ability to organise a packed soundstage into something that’s easy to understand is unrivalled at this price. And in any circumstance, the irDAC is amazingly dynamic.
We don’t think you own a digital device that wouldn’t benefit from having this Arcam take care of the DAC stuff. And it can do it while you’re glued to the sofa, so it’s win upon win.
