If you’re spending big on a pair of headphones – and why wouldn’t you? – a dedicated headphone amp can really make them sing.
So what should you look for in a headphone amplifier? Analogue inputs mean you can plug in a traditional source, such as a CD player, but more modern amps boast digital inputs and a built-in DAC. This is ideal if you’re listening to music stored on a computer. A good headphone amp can be the basis of a compact and effective desktop hi-fi system.
Size and portability are also key considerations. Some of the below will happily slip into a jeans pocket and, with the right cables and connectors, can even be paired with a mobile phone. Other models command that you clear your desk. So, decide whether you’ll be listening to your headphones on the move or solely at home. We’ve rounded up the best headphone amplifiers money can buy, including budget, mid-range and high-end options.
The Award-winning soundKey is a fantastic piece of kit, and is highly affordable too. It’s built to handle all manner of file types, including MP3, AAC and FLAC, and the sound is spot on – spacious presentation is the order of the day, giving each instrument the space it needs to breathe. The result is a gloriously detailed soundstage that will do mobile listeners of all stripes proud.

Another Award winner, this amp is a little pricier than the soundKey, but you can hear where your extra money’s going: the sound is more dynamic, with more weight and body. There’s also an extra level of detail that, combined with excellent low-level dynamics, means everything sounds more natural, subtle and expressive sound. The logo even lights up different colours to tell you what file format the Red is processing. It’s a nice touch to an already excellent device.

The Mojo boasts much of the same sound prowess as the Chord Hugo, but without the price tag of its more expensive sibling. Its footprint is barely bigger than a credit card, but there’s space for plenty of connections, including micro USB, optical and 3.5mm headphone jack. The sound is packed with detail, bursting with insight, and all comes together to form a fully cohesive whole. Highly recommended.

There aren’t many headphone amps that sing as sweetly as the Hugo 2. It’s small enough to take with you (there’s a built-in battery), but a little too large to sit in a pocket, so it’s not ideal for on-the-go listening. It’s not the easiest device to use at times, but you’ve plenty of inputs to take advantage of, plus aptX bluetooth. See past its quirky looks, and you’ll be rewarded with a handsomely detailed, dynamic and punchy performance.

As you can see from this list, Chord knows how to make a decent headphone amplifier-cum-DAC, and the Hugo TT2 is a high-end delight. It’s hugely impressive and not just in the looks department. There are multiple digital inputs of the optical and coaxial variety, plus USB and aptX Bluetooth. There are no fewer than three headphone outputs too. File support is extensive as you’d expect, but it’s the sound quality which is truly spectacular. Taking everything in its stride, the Hugo TT2 is one of the most finessed and transparent-sounding devices you’re likely to hear.

Be warned: this amp is a little basic, with no built-in DAC, but the sound quality is superb. There’s no harshness or edginess at the top of the frequency range, bass notes are bedded in nicely without being overbearing, and vocals are placed precisely where they should be. So if you can live without the DAC, this should make your shortlist.

This is a step up from the budget models mentioned earlier. Arrangements are rhythmically sound, the timing is crisp and the sound is effortlessly energetic. There’s also a ‘Bass Boost’ setting which puts the emphasis firmly on the low end. It’s up against some stiff competition but this Oppo has enough features to make it an easy recommendation.

This is very much a desktop amp – if you’re looking for something portable, best look elsewhere. But if it’s home headphone listening you’re after, it could well be the one for you. The M-DAC+ shows a slavish attention to detail, fantastic powers of organisation and a rhythmic assurance that few can match. This is a solid headphone amplifier that truly justifies the outlay.

Again, home listening is the name of the game here, but that’s no bad thing. The Naim is a big, full-bodied performer with superb rhythmic ability, showing real precision and a fantastic level of bite. And it manages to keep everything organised without ever sounding clinical or disjointed. The low end is powerful, the midrange strong and focussed, while the treble remains balanced and refined. A true five-star product.

The iFi xDSD has a number of strings to its bow, including a built-in battery pack (good for around 6-8 hours), aptX Bluetooth and extensive hi-res file support. There isn’t much this device can’t do and its sound quality is good enough to earn it a solid recommendation. It’s not the most detailed or rhythmic sound on the headphone amplifier market, but it sounds clean, organised and evenhanded in its approach to music.

Eight grand sounds like a lot of money – and indeed it is – but if you’re one of the lucky few with a huge budget, then you should definitely get to know DAVE. It is quite simply the best DAC money can buy, despite the fact that setting it up is not as straightforward as it could be (Chord hasn’t seen fit to label any of the ports). But once you do fire it up, you’ll struggle to find a weakness – the soundstage is excellent, managing to be precise, layered and neatly arranged, while the tonal balance is even-handed and utterly convincing. But it’s the dynamics that really impressed us the most. This headphone amplifier has to be heard to be believed.
