FiiO's portable hi-res DAC and amp is priced to make you an audiophile, right before hi-res goes 'truly mainstream'
Curious? You're not alone – meet QX13

- FiiO wants you to know that hi-res audio's about to go 'truly mainstream'
- …and the QX13 is priced to reflect that
- Made from 21 layers of carbon fiber for a lightweight yet durable build
You know what my favorite kind of audio gadget is? One that makes people go 'What is that?' ideally with the follow-up question, 'And also, what do the numbers mean?'
This is one such piece of kit. It's almost like the handheld super-computer Ziggy in Quantum Leap – because while nobody really understands everything about it, everyone agrees it's a Good Thing. And with Spotify HiFi launch rumors gathering momentum (recent reports suggest it might land in late 2025, and be called 'Spotify Music Pro'), when hi-res goes mainstream, you don't want to be left unable to take advantage…
What you're looking at is the FiiO QX13, a pocket DAC and headphone amp for your phone, laptop, or games console – a gateway to the world of hi-res audio on the go. And although it is a flagship product and one that marks 18 years of FiiO’s audio expertise, it isn't particularly pricey either.
New to the world of headphone DACs? That's fine: every product you own that accepts and plays a digital music signal (your phone, wireless earbuds, laptop, Bluetooth speakers, and so on) has its own built-in DAC.
The thing is, many of them are inexpensive, and adding a standalone dedicated (read: better) option to the audio path can level up what you hear a lot. Additionally, the added amplification can help give oomph and volume to hard-to-drive headphones wired up to your phone or a portable player.
How does this particular DAC work? Add any audio source with USB-C, and you've got it. You just breathed new life into your wired headphones.
The QX13 can fully decode MQA music and is compatible with file formats such as DSD512 and 768Hz / 32-bit tracks. A 3.5mm and balanced 4.4mm headphone socket ensures wide compatibility with all headphones, too.

DAC's right
And it's quite a looker, no? The QX13 is made with 21 layers of carbon fiber for a lightweight yet durable build to show off its "extra large" 1.99-inch hardened IPS color display.
The QX13 also introduces the flagship Ess Sabre Pro ES9027PRO chip, recommended for use in full-size hi-fi systems. However, FiiO has achieved a "micro DAC/AMP design" created to make the most of your headphones and IEMs. The chip features 8 channels set up in parallel, and is paired with two ultra-low-noise ES9312 regulators for precise output matching on each audio channel.
Of course, FiiO would point you towards its own IEMs to pair them with – possibly the FiiO FH19 (which are very good indeed) and FiiO notes that the QX13 arrives with an (optional) magnetic leather case, compatible with the custom FiiO power 'estick' pack for lightweight portability with powerhouse performance in Desktop Mode. Choose the magnetic leather case to combine both devices in one unit.
The QX13 is now available, priced $219 / £219 (around AU$450), and if that sounds a little rich for your blood, note that rival iFi's flagship DAC, the iFi iDSD Valkyrie, comes in at a cool $1,699 / £1,699 / AU$2,999 (approx). So, there's that option also…
