Best stereo amplifiers 2024: the best integrated amps for every budget
Best stereo amplifiers: quick menu
A stereo amplifier is the beating heart of any hi-fi separates system; the necessary middleman between a source (such as a CD player, turntable or music streamer) and a pair of passive loudspeakers. Without one, you simply don’t get a sound, and which one you pick will greatly impact your system’s sonic quality and character.
If you’ve chosen to go down the simpler, most convenient and space-efficient option of a one-box integrated amplifier, as opposed to a pre/power pairing (where preamp and power amp duties are housed in separate boxes), you’ve come to the right place.
What Hi-Fi?’s testing process is uniquely comprehensive. We pride ourselves on reviewing every corner of the stereo amplifier market, often being one of the – if not the – first hi-fi publications to get their hands (and ears) on newly announced models. And every amplifier under scrutiny is compared to the class leader at its price point in our dedicated listening rooms. That thoroughness and wide contextual knowledge allow us to confidently pick the best stereo amps across various budgets.
The eight class leaders below – five of them current What Hi-Fi? Award winners – cover a great variety of features and connections, but they all have one crucial thing in common: benchmark performance at their respective price points.

I’m the managing editor of What Hi-Fi? and have been testing hi-fi and audio equipment for over a decade, including my fair share of stereo amplifiers. An amplifier is the centerpiece of a system, through which music flows both into and out, so it’s crucial to get the best performer and partner for your source and speakers that you can afford – and that’s where this carefully curated list comes in. There’s something to suit all budgets and connectivity requirements here, to get your system singing whether it comprises a modestly priced turntable paired with entry-level speakers, or indeed higher-end kit.
The best stereo amplifier overall

Previous Arcam efforts have always looked tidy, but the British brand’s new Radia range, with the all-black finish and subtle yellow accents, looks sleek and modern. Of course, the best part of the Arcam amplifier makeover doesn’t concern aesthetics…
The middle-sitter in a range of three, the A15 has this powerful, precise and poised character regardless of the input chosen. “Arcam was one of the pioneers of outboard digital-to-analogue converters back in the ’80s and that experience shines through in the performance of the A15’s digital section,” our in-house reviewers note in our A15 review. “It is crisp, insightful and engaging.”
We are also impressed by the scale of the sound – “stereo imaging is expansive, stable and nicely layered,” we wrote – as well as how it handles music’s savage dynamics. There is no shortage of punch and power, but this is no muscle-bound thug; the A15 is insightful and subtle, able to track multitudes of instrumental strands with skill.
Once we had heard how good Arcam’s entry-level A5 (below) sounded, we were a little worried for the A15 – but we needn’t have been. It is clearly better than its talented sibling, delivering a sound of greater clarity, scale and precision that justifies its extra price tag and represents a logical step up.
Better yet, there’s a moving-magnet phono stage built in, which is something its closest rival, the Cambridge Audio CXA81 (formerly found in this very spot) doesn’t offer – and nor does its brand-new replacement, the CXA81 MKII. The new (and old) Cambridge model does reply with a USB input, though, so if that’s important to you then consider it a recommendable alternative.
Otherwise, make sure you give the A15 a listen if it falls within your budget; we haven’t heard a better-sounding alternative for the money.

The best entry-level stereo amplifier

The Marantz PM6007 takes the winning formula of the Marantz PM6006 UK Edition, a former What Hi-Fi? Award winner, and manages to squeeze even more performance out of it. The result: another What Hi-Fi? Award winner.
Let’s get the negatives out of the way first, though. There’s no USB input or Bluetooth connectivity, which some users might demand. That aside, however, the PM6007 is pretty much faultless.
It boasts trademark Marantz styling and is a solidly built. As our expert reviewers noted in our PM6007 review, it has “a well-constructed, well-finished chassis that, while perhaps too densely populated with dials for some minimalist tastes, offers traditional hi-fi appeal”.
Improvements include a new DAC and new filters, which can be switched between when you’re using the amp’s digital inputs, plus new components in the power amp and phono stages. The latter also gets upgraded circuitry.
The results speak for themselves. While the PM6007’s vocal delivery doesn’t feel “as rock-solid and grounded as its predecessor’s”, to quote our review, everything else has moved forward – there’s greater clarity, texture, precision and rhythmic punch. The sound is recognisably smooth, full-bodied and balanced, with a pleasing spaciousness, making it another quality hi-fi amplifier from Marantz that should please most people and systems.
There aren’t many alternatives around this price point that we can heartily recommend, but the high-performing Mission 778X at £549 / $549 / AU$1099 is one to consider if you want Bluetooth and a USB, or simply value retro aesthetics and/or a half-width chassis.
If you’re looking for an even cheaper option than either, however, we would point you to the five-star Rega io and Cambridge Audio AXA35, which are both brilliant ‘my first amplifier’ options.

The best budget stereo amplifier

Arcam’s once dominant presence in the affordable stereo component market definitely waned in recent years, leaving the likes of Cambridge Audio, Marantz and Rega to take bigger pieces of the pie. Cambridge Audio’s CXA61 sat in this very spot on this list for many years, in fact. That it no longer does tells you a lot about how good Arcam’s new A5 is. Like its next-level-up A15 sibling (at the top of this list), the A5 is a stonkingly good stereo amp for the money.
It may be the most affordable amplifier in the all-new Radia range, yet it perfectly encapsulates what the company is trying to do. To our eyes, this is a fresh and modern-looking product; and to our ears, it is just as attractive.
An amplifier at this price point is as likely to be partnered with budget kit as it is more premium offerings, so it has to be forgiving enough not to emphasise the shortcomings of more limited partnering equipment, yet still have the insight and transparency to make the most of more capable partners.
As our reviews team was pleased to report, the A5 manages this balancing act superbly. “It has a sweet nature that while full-bodied and smooth never errs far enough to rob the life from the music,” reads our A5 review. It’s controlled and remains composed even when the music gets dense, and lows are pleasingly well-defined, authoritative and agile.
Turntable owners will be pleased to read that the phono stage is a good one – clear and expressive – while the DAC stage feeding the coaxial and optical inputs is of similar satisfying quality.
Partner the Arcam with suitably capable sources and speakers, and it will invariably deliver musical and enjoyable results. It has been many years since we’ve heard such a convincing stereo amplifier from Arcam. If you are thinking of buying at this level, this one has to go at the top of your shortlist.

The best mid-range stereo amplifier

The successor to the multi-award winning Rega Elex-R, one of our favourite amplifiers of the last decade, is thankfully far from a disappointing sequel.
Revealing and faithful, it’s sonically capable in ways far beyond our expectations at this mid-tier price point. The elegant, confident way it delivers music is very rare at this level. As our expert reviews team noted in our Elex Mk4 review, “We struggle to focus on particular strands or frequencies to critique, and instead are content listening to track after track and marvelling at how the Rega turns its hand to every song. It simply doesn’t impose itself on the music. That’s a huge accomplishment in its own right.” At this price, it’s the most entertaining amplifier we’ve heard – lively, full-bodied and with tip-top timing that truly underpins rhythms.
The addition of digital inputs (at last!) and a headphone port is a great step in the right direction, too, particularly given their good quality, giving customers more flexibility in how they listen to this terrific amp.
If you take the time to partner it carefully (we’d avoid any bright or forward-sounding kit as a rule; pairing it with speakers with more richness to the tone – like the KEF LS50 Meta or Wharfedale Linton – will give the sound more body and weight), this stereo amplifier will work wonders.
If you can stretch your budget further, Rega’s Elicit MK5 is a similar but superior-sounding proposition that will set you back a bit more – a great and slightly more affordable alternative to the Naim Nait XS 3 below.

The best premium stereo amplifier
Image 1 of 3
This is the third-generation instalment of a model first introduced in 2008. The XS 3 adds a moving magnet phono stage and better responsiveness, and that’s about it. If that sounds negative, it shouldn’t – the XS 3 is a killer stereo amp, having earned a well-deserved five stars and multiple What Hi-Fi? Awards for its trouble.
Why? Attention. To. Detail. Open it up and you’ll see what we mean – there’s immaculately assembled audio circuitry, with fantastic care shown in reducing the degrading effect of outside interference and unwanted interactions between components, down to the way the connecting wiring is shaped and the exact number and placement of the tie clips used to hold it in place!
Such engineering care shines through the Nait’s performance. The sound is much crisper and more agile than its forebear. It might not be enough of a difference to justify upgrading from its predecessor, but it still makes for an awesome amp nonetheless. There’s a combination of insight, dynamic subtlety and rhythmic drive that’s hard to better at this level, with energy on tap and a good degree of refinement when required.
The new phono stage proves a worthy addition, too. While phono circuits integrated into stereo amplifiers aren’t always of great quality, the one in the XS 3 bucks that trend. Our in-house reviews team described its “detailed and punchy performance that brims with energy and interest,” to quote our Nait XS 3 review.
Ultimately, the Nait XS 3 delivers the music with emotional impact intact – and that’s all anyone could ever ask of it.
Read our full Naim Nait XS 3 review
If anything on this list has stood the test of time, it’s the Nait XS model. I’ve loved listening to it over the years. Just be aware that it doesn’t have digital connectivity, which you might find slightly surprising in this day and age. But I – and I’m sure Naim! – would argue that an outboard DAC would be a better solution anyway at this level, and at least this way the XS 3’s analogue performance doesn’t suffer from any digital integration.
The best stereo amplifier for purists

The Rega Aethos delivers a fantastic fusion of insight, dynamics and rhythmic precision to produce a class-leading sound at this serious level. It’s not the most highly-specced stereo amp we’ve seen: there are no digital inputs (something Rega is now starting to add in its newer releases), nor is there a phono stage for a turntable, which is perhaps the more surprising omission given Rega’s record player heritage. So those wanting to connect digital sources or a phono-less turntable should seek an outboard DAC and/or phono preamp.
You do get five line-level inputs and a 6.3mm headphone socket, though, and for those who don’t care much for digital (or have another solution to get it), that’ll do very nicely.
If you can live with that, the Rega will reward you with a captivating sound that majors in clarity and dynamic fluidity. It’s clean, coherent, forthright and uncovers unprecedented insight at this level. Its sense of timing is second to none at this price, which is part of the reason it is a current What Hi-Fi? Awards winner.
Just note that tonally it sits just on the lean side of neutral, albeit in no way sounds thin or undernourished. Our expert reviewers suggest in our Aethos review that “it’s best to avoid systems that already edge towards brightness or aggression; it is a revealing amplifier that doesn’t go out of its way to hide the shortcomings of its partnering source or speakers.”
Performance-wise, the Aethos is our definitive number-one pick at this level. That said, if your budget can stretch a bit further but you don’t have high-end money to spend on the Lavardin ITx below, the competitively performing Naim Supernait 3 (phono inclusive), Rotel Michi X3 (phono and digital) and Cambridge Audio Edge A (digital and Bluetooth) are all worthy alternatives if you crave more features than the line-level-only Aethos offers.

The best high-end stereo amplifier
Image 1 of 4
The Lavardin ITx is one of the most uncluttered and self-effacing amplifiers we’ve ever heard. “Its presentation isn’t warm or rich in the manner of some valve designs,” notes our ITx review, “but it is incredibly sweet sounding, in all the best ways. This is also a fast and fluid performance, one that’s immensely precise without sounding clinical in any way.”
Its stereo imaging is wonderfully expansive and impressively precise, richly textured and a musical champ.
It isn’t a stereo amplifier that encourages over analysis of the hi-fi system or the recording being played. It is more than transparent enough to perform that role but prefers to put the spotlight firmly on the music. That’s the way we like it, and we rarely come across a product that sounds ‘just right’. Does the ITx live up to our fond memory of the original from the late ’90s? Yes, it absolutely does.
Just be aware that this is nothing other than an integrated amplifier for purists. The ITx’s connectivity is limited but adequate for most stereo setups. There are four single-ended line-level inputs, a lone tape output and a pair of modest-looking speaker terminals. So if you play records or use headphones, make sure to budget for a phono stage and headphone amplifier to do those jobs.
If you’ve got more to spend, the Luxman L-509Z is also an excellent performance-first choice, while the digital-friendly Copland CSA 100 is a slightly more affordable and versatile option to consider.

The best desktop stereo amplifier
Image 1 of 4
Chord Electronics has proven to have quite some talent in finding new market niches, and the diminutive Anni desktop stereo amplifier is a perfect example of that.
It truly is a proper Chord amplifier in miniature, using as it does the Ultima dual feed-forward circuitry seen in the latest generation of the brand’s high-end power amplification. However, the Anni is only the size of the Chord Qutest digital-to-analogue converter and is intended to be an ideal partner for that DAC and the company’s Huei phono stage.
While it could drive big speakers in a traditional setup, a 10-watt-per-channel power output will only go so far in such a situation, and really it’s designed for desktop use with either headphones or suitable speakers. Our reviews team tried it in a computer and headphones system, as well as with a mature, conventional speaker-fronted one, and it worked well with both.
Despite its diminutive size and limited connectivity (two analogue inputs), the Anni is among the most capable desktop/headphone amplifiers we’ve heard. It sounds clean, clear and articulate yet is able to communicate the energy and drive of upbeat songs too.
The Anni is a surprising product when used with speakers. It delivers a scale and solidity of sound that belies its tiny stature, though don’t expect the muscle and authority a conventionally sized class leader, like the Arcam A15, can deliver. This Chord delivers a fuller, more robust presentation than we’ve come to expect from the brand, but it still renders enough in the way of detail and transparency to satisfy.
Use it as a desktop amplifier as intended and it shines. Sure, there are operational quirks – something that’s proving to be a Chord trait – but when the Anni sounds this good we can forgive a lot.
For a much more affordable but similarly sized, desktop-friendly alternative, consider the NAD D 3020 V2.

Also consider
- Rega io: If you’re looking for a more affordable amplifier than any on this list and don’t need digital connectivity, this Rega has been a favourite of ours for years. No, it isn’t all that well equipped, but sonically it’s bags of fun and hugely entertaining.
- Naim Supernait 3: A better-equipped alternative to the Rega Aethos on this list thanks to its inclusion of a phono stage. The Supernait is also a remarkable all-round performer and recommendable for anyone who favours Naim’s authoritative and dynamic sonic character.
- Luxman L-509Z review: A great high-end alternative to the Lavardin for those who want both aspirational performance and modern-day features. This all-rounder proves that comprehensive functionality and great sound are not mutually exclusive.
How to choose the best stereo amplifier for you
Firstly, you should consider what sources you have and how you want to connect them. Stereo amplifiers aren’t as simple and stripped back as they used to be; the days of equipping them with just analogue inputs and outputs and a pair of speaker terminals are now no longer the norm.
With laptops, phones and music streaming services becoming ever-more popular music sources, the integrated amplifier has indeed moved with the times. Many now contain built-in digital-to-analogue converters (DACs) that feed digital inputs for connecting laptops, hard drives and digital-savvy hi-fi sources. This is convenient, though note that not all digital stages are implemented as well as analogue ones, and higher-end systems may benefit from an analogue-only amplifier design paired with an outboard DAC.
The vinyl revival has seen many integrate phono stages for turntables, too. Some have Bluetooth for added wireless convenience, while others boast wi-fi/Ethernet complete with network streaming to make them fully-fledged, just-add-speakers systems, otherwise known as ‘streaming amplifiers’ (and for the best of those, you’ll want to head on over to our best hi-fi systems page). So what you require will depend on your needs and the connectivity of any existing equipment you have.
You should also consider your amp’s partnership with your speakers. The speaker/amp relationship not only comes down to an amp’s power output but also the speaker’s impedance characteristics and sensitivity. There are tonal characteristics to take into consideration too to ensure the best sonic synergy. So if you need clarification on system matching, you should head over to our thorough how to choose and set up a stereo amplifier advice page.
How we test stereo amplifiers
We have state-of-the-art testing facilities in London and Reading, where our team of experienced, in-house reviewers test every bit of hi-fi and AV kit that passes through our door. Every stereo amplifier we test takes up residency in one of our two reference hi-fi rooms for the duration of its review.
What Hi-Fi? is all about comparative testing, so we listen to every stereo amplifier we test against the current leader – often a What Hi-Fi? Award winner – in its class to gauge how it compares to the competition. We keep Award-winning products in our stockrooms so we can always put new products against ones we know and love. We do our best to review as many new models in as many markets as possible, too, ensuring our contextual knowledge is the best it can be. And we encounter even more during our What Hi-Fi? Awards judging in autumn, where we listen to every amplifier manufacturers submit.
We are always impartial in our testing and ensure we hear every stereo amplifier at its optimum. So we’ll use different partnering products – those in our high-end reference system as well as more price-comparable ones – and ensure we listen through an amp’s multiple connections to test both its analogue and (if applicable) digital output stages. We also try plenty of different types of music and naturally give them plenty of listening time (and time to run in) too.
All review verdicts are agreed upon by the team as a whole rather than an individual reviewer to eliminate any personal preference and to make sure we’re being as thorough as possible. There’s no input from PR companies or our sales team when it comes to the verdict, with What Hi-Fi? proud of having delivered honest, unbiased reviews for decades.

F.A.Q.
Should you buy an integrated amp or separate pre and power amps?
Integrated amplifiers pack both pre- and power amplification into one box, and all of the stereo amps on this list are this type. The advantage is neatness due to fewer boxes and cables and the fact that the pre and power stages will have been tuned to work optimally together.
Alternatively, you can buy individual preamplifiers (which essentially handle input selection and volume control) and power amplifiers (which increases the amplitude of the audio signal) and these have advantages, mainly in that they keep the sensitive preamp circuitry away from the electrically noisy high-current power amplifier section, and having separate power supplies helps improve sound quality too. It generally makes sense to pick a pre and power pairing from the same manufacturer as they will have been tuned together.
More information can be found in our how to choose and set up a stereo amplifier article.
Can you get stereo amps with HDMI?
Most stereo amplifiers will offer digital connections such as optical, coaxial and USB, though fewer include HDMI ARC ports for hooking up your TV. HDMI is much more common on surround sound-savvy AV receivers.
However, some people like to use their stereo system to make their television sound better, and including HDMI is a neat way of making that happen. Cambridge Audio has recognised that with its Edge A integrated by including an HDMI ARC socket. Other examples with HDMI ARC include the NAD C 389, Audiolab 7000A and the more home cinema-aligned Marantz Stereo 70.
Stereo amp or receiver?
You may see integrated amplifiers labelled as ‘stereo amplifiers’ or ‘stereo receivers’. They are essentially the same thing, though the term receiver indicates that the amplifier has FM/AM and/or DAB radio built-in and therefore can play radio channels through connected speakers without requiring a source. An example of this is the Yamaha R-S202D.
These are less common nowadays as internet radio and DAB are often built into source components.
