Best stereo amplifiers 2022: the best integrated amps you can buy

Best stereo amplifiers 2022: Welcome to What Hi-Fi?'s round-up of the best stereo amplifiers you can buy in 2022.

A stereo amplifier is the beating heart of any hi-fi separates system; the necessary middleman between a source (such as a CD player or turntable) and pair of passive loudspeakers. Without it, you simply don't get a sound!

If you've chosen to go down the simpler, most convenient and space-saving option of an 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.

Here, we've rounded up the market's best stereo amps, which offer a vast selection of features across a range of prices. We're confident there will be something here to suit all budgets and requirements, to get your music system singing whether it comprises a modestly priced turntable and entry-level speakers or higher-end kit. And what better place to start than with the current What Hi-Fi? Award winners...

How to choose the best stereo amplifier for you

Why you can trust What Hi-Fi? Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

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) complete with digital inputs for connecting to laptops, hard drives and digital-savvy hi-fi sources, while the vinyl revival has seen many integrate phono stages for turntables. Some even feature network streaming, making them a fully-fledged, just-add-speakers system (and for the best of those, you'll want to head on over to our best hi-fi systems Best Buy). 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. So if you need clarification on system matching, you should head over to our thorough how to choose and set up a stereo amp advice page.

Best stereo amplifier: Marantz PM6007

No Bluetooth or USB

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 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, but that aside the PM6007 is pretty much faultless.

The PM6007 boasts trademark Marantz styling and is a solidly built, nicely-finished integrated amplifier with 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.

And the results speak for themselves. The sound is smooth, full-bodied and balanced, with a pleasing spaciousness. Another quality hi-fi amplifier from Marantz.

Nothing at this price

Despite some minor cosmetic tweaks, the CXA81 might look a lot like its predecessor, the CXA80, but all the improvements are where it counts: on the inside. 

Cambridge Audio's engineers have upgraded the signal path, as well as the capacitors in both the preamp and power amp sections. Also on board is a new DAC and an improved USB input that supports hi-res audio. 

What does this all mean? It means there's a world of difference when it comes to performance. It's as punchy as anything, with a bold, powerful sound. Yet detail is never sacrificed, and it's lean and agile enough to handle anything you can throw at it. 

Add in the addition of aptX Bluetooth for wireless playback, and you've got the best stereo amplifier around at this price and a very worthy What Hi-Fi? Award winner. It sets a new standard for hi-fi amplifiers in this price bracket – one we can't see being surpassed any time soon.

No digital inputs

This excellent budget integrated amp borrows the power amp and moving magnet phono stage from its elder sibling, the Rega Brio, which you'll find in position six on this list. And it's quite obvious when you power up the io that it's a descendant of this excellent amp. It showcases a fantastic sense of rhythm, impressive dynamics, detail. In short, it's a whole lot of fun to listen to.

One slight drawback is that in order to reach this level of audio quality, Rega has made the decision to stick purely with analogue inputs. The lack of any digital connectivity might be a hindrance to some, but it's not unheard of at this price point, and it doesn't dampen our enthusiasm for what is one of the best stereo amplifiers we've heard at this modest price.

Bettered for features

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.

And it shows. The sound is much crisper and more agile than its forebears, thanks in no small part to this exacting eye for detail (it even goes as far as the shape of the connecting wiring and the exact number and placement of tie clips holding it in place). It might not be enough of a difference to justify upgrading from its predecessor, but it still makes for an awesome amp nonetheless.

So not a massive change, as we say. But if it ain't broke...

Pricier than the previous model

The CXA61 is the lower-specced stablemate to the CXA81 further up this list, and successor to the CXA60, a winner of multiple What Hi-Fi? Awards. So it's in good company. 

Thankfully, it doesn't let the side down: it has the same digital inputs and Bluetooth capabilities as the CXA81, but only outputs at 60W per channel instead of 80W, giving you less power. But for most listening scenarios, that won't be a deal breaker. 

What's more important is the sound quality. And we're happy to report it's a real step on from the CXA60, being more transparent and fun, but always staying composed even when the music gets frantic. It's a presentation style that works well across a wide range of musical genres and speakers, and should please all but the most demanding of listeners. If that's you, you'll have to spend a little more to satisfy your audio taste buds.

Best stereo amplifiers: Rega Aethos

This Rega's sense of timing is second to none at that level (Image credit: Rega)
A superb stereo amplifier that justifies its premium price tag.

The Rega Aethos delivers an fantastic combination of insight, dynamics and rhythmic precision to produce a class-leading sound. It's not the most highly-specced stereo amp we've seen, though. There are no digital inputs, nor is there a phono stage for a turntable, which is surprising at this level. You do get five line-level inputs and a 6.3mm headphone socket, though.

IF you can live with that, the Rega will reward you with a captivating sound, that majors in clarity and dynamic fluidity. Its sense of timing is second to none at that level, which is part of the reason it is a What Hi-Fi? Awards 2022 winner.

Needs careful system matching

The new Elicit MK5 is one step down from the award-winning Aethos above and marks a surprising change of direction for the company’s amplifier designs.

Rega products tend to be pretty purist affairs that prioritise performance and solid engineering above all else. They rarely excel on the features front, but that seems to have changed with the Elicit MK5, since it now includes digital optical and coaxial (though sadly not USB) inputs alongside the usual analogue connections.

Just over 30 years on from the original, the Elicit integrated remains an excellent choice for those that prioritise sonic performance - one that's taut, punchy, clear and simply one of the most musical at this level. Recommended? You bet.

Best stereo amplifiers: Chord Anni

Chord Electronics has proven to have quite some talent in finding new market niches. And the diminutive Anni desktop integrated amplifier is a perfect example of that.

Make no mistake, this really 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, this little box is only the size of the Chord Qutest digital-to-analogue converter – for the uninitiated, think smaller than a pair of coasters laid end-on – and it’s intended to be an ideal partner for that DAC and the company’s Huei phono stage. The important thing to note is that it’s designed for desktop use with either headphones or suitable speakers.

This is one of the most capable headphone amplifiers we’ve heard. It sounds clean, clear and articulate yet captures the manic energy of Nick Cave & The Bad Seed's Babe, I’m On Fire superbly.

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.

No digital inputs

If it's heritage you want, the Rega Brio has it in abundance. The original Brio launched in 1991, when Bryan Adams was topping the charts with (Everything I Do) I Do It For You. And it wears its heritage on its sleeve, with a redesign that harks back to those earlier models.

It's now in its sixth generation, and we had to wait six long years for this model to touch down. Thankfully, it was worth it.

This is the kind of amplifier we want to leave on and play our entire music collection through. Again and again. 

Yes, your main inputs are limited to standard RCA sockets and a moving magnet phono stage, but we're willing to overlook this, given the amp's amazing sense of musicality. It sounds terrifically fluid with precision and scale in spades. In fact, almost anything you play on it will sound amazing. Even Bryan Adams.

Best stereo amplifier: Rotel Michi X3

Reasons to buy

+
Muscular yet impressively controlled

Taut, punchy and agile bass
+
Exceptional build and finish

Reasons to avoid

-
Phono stage is moving magnet-only
-
Digital module isn't standout

Accuse a person of lacking character and it’s a harsh assessment. For a piece of hi-fi though, it’s hugely positive. This Michi is a firmly ‘hands-off’ performer. It doesn’t imprint a strong sonic signature on anything it plays, leaving the character of the sound to come from the recording or some other part of the system. Tonally, it sounds even-handed to us, delivering all parts of the frequency range with equal importance. 

Detail levels are high, as is the quality of stereo imaging. And one of the highlights is undoubtedly the Michi’s bass delivery, which makes most of the competition at this price point sound a little soft and blurred in this region. The Cambridge Edge A (below) is perhaps the closest in terms of build and ability, but while it has a more fluid and engaging presentation, the X3 still has the advantage when it comes to clarity, sonic precision and price.

Ultimately, this Rotel is a formidable performer that’s ready to mix it with the best at the price. Add the exceptional build and comprehensive specifications to the hugely capable sonic performance and it’s a must-have on your shortlist.

As far as flagship stereo amplifiers go, the Edge A is a stunning piece of kit. The casework looks slick thanks to its curved corners, while the knurled input selector ring works with wonderful precision. It even comes with a classy remote handset. Features include an array of digital and analogue inputs including balanced XLRs and USB (type A), plus Bluetooth aptX HD, and even an HDMI ARC socket to help your TV sound better.

And the Cambridge sounds like a truly complete amplifier for the money. It generates a huge sense of authority and scale, with amazing dynamic reach. The amp also has a fantastic grasp of low-level details, thanks to a display of clarity and control you'll struggle to beat at the price.

If you're looking for a fit-and-forget hi-fi amplifier, we can't think of anything better at this level.

No digital inputs

This is another integrated amp with some serious pedigree. This third-gen model doesn't break any moulds, but then it doesn't have to. A slight improvement on its predecessor would be enough to make it one of the best around in its category.

And that's exactly what we have here. Changes over the previous version are limited to the addition of a (good quality) moving magnet phono stage and a tweak in the power amplifier section. It makes the Supernait a little more useful and a little bit better. But such was the quality of its predecessor that that's enough to keep the Supernait at the cutting edge at this level.

Some may baulk at the lack of digital inputs, but these can harshen the analogue performance. And they never sound as good as a dedicated outboard unit like a Chord Mojo 2. So we support Naim's decision to keep it strictly analogue.

It certainly shows when it comes to sound quality. In fact, we can't think of a more talented alternative when it comes to punch, dynamics and rhythmic drive.

Reasons to avoid

-

No Bluetooth

Let's be honest, the world of budget stereo amplifiers isn’t exactly brimming with superstar products. So when we come across something as talented as Cambridge’s AXA35 we’re especially pleased.

This is a well-built, cleanly styled product that packs all the essentials. True, we’d like to see Bluetooth as well as a couple of physical digital inputs, but we’re willing to overlook such things when the amplifier is as sonically capable as this. And if you have a budget turntable, you can take advantage of its built-in moving magnet phono stage.

The AXA35 delivers a bold and composed sound that practically overflows with detail. It’s an even-handed performer that’s as happy playing a large-scale Mahler symphony as it is Jay-Z’s latest, along with everything in between. And when it comes to rhythmic drive and dynamic expression, few alternatives do better. 

At this price, you really can't ask for more.

Nothing really at this price

If you want an interesting alternative to the budget Marantz, Cambridge and Regas above, then we suggest the NAD D 3020 V2. It has a smaller design, and the fact it can stand upright means it's more versatile with positioning. 

The NAD is also packed with useful features. There's Bluetooth for offline streaming and a moving magnet phono stage for connecting a turntable. Which give you far more options when it comes to audio sources. Plus you get optical, coaxial and RCA connections, along with a subwoofer out for adding lashings of bass.

And if this wasn't enough, it's an enjoyable listen too. Dynamics and timing are up there with the best, while detail levels are impressive for this class. Even if the Marantz does pip it for all-round sound quality, this NAD more than makes up for it in terms of features and ease of use. Definitely one for your shortlist.

Fierce competition

Arguably, this is the only stereo amplifier at this price capable of troubling the Rega Brio (at no.6). So needless to say the Audiolab 6000A is a very accomplished performer. 

It's well-equipped on the connections front - four digital inputs, three analogue inputs, and a pair of moving magnet phono inputs. Add Bluetooth and a headphone output to the equation and you've got a list of options the Rega simply can't match. 

So how does it sound? Very good indeed. Though considering it uses technology derived from the top-of-the-range 8300A series, and the same DAC chip as the Award-winning Audiolab M-DAC, its prestige audio quality comes as no surprise. 

The 6000A's open and airy presentation gives music plenty of room to breathe and there's bags of refinement on offer too. It's clean and articulate, with a gorgeous sense of clarity and an absolute tonne of detail to get your teeth into. Take it from us, the 6000A doesn't disappoint.

Best stereo amplifier: Musical Fidelity M2si Integrated Amplifier

One of the most stripped-back amplifiers we've ever tested, but also one of the best sounding at this price (Image credit: Musical Fidelity)
Short on features but still a superb stereo amplifier.

Specifications

Power: 60W per channel
Phono stage: No
Digital inputs: N/A
Bluetooth: No
Headphone output: No
Dimensions (hwd): 10 x 44 x 40cm

Reasons to buy

+
Expansive and fluid sound
+
Impressive dynamics
+
Refined yet muscular performance

Reasons to avoid

-
Line level unit only
-
No headphone out

Let's start with the negatives. The Musical Fidelity M2si doesn't have the features list of most rivals – there are no digital connections, no phono stage and no wireless connectivity. In fact, it's one of the most stripped-back amplifiers we've ever tested. But that means every penny you spend on it goes straight to making a great-sounding amplifier. 

So what do you get for your money? There's a remote control, six line level inputs, including a tape loop and a home cinema bypass option to help integration into a surround system. It feels better built than many rivals, too, while the simple, clean cut design will appeal to many. 

Sound-wise, its performance is massively refined and pleasantly entertaining, and leaves plenty of scope for upgrades. It's a large-scale sound, packed with authority and substance. It images very well, and dynamic expression is another strong point.

In short, a superb all-rounder. Whatever you throw at it, it never disappoints.

Dan D’Agostino Master Audio Systems (to use the company's full name) only plays at the top table. Despite its hefty price tag, the Progression Integrated amplifier is the starting point for the brand's range, but that doesn’t make it a diluted facsimile of products further up the chain. It’s more like everything the brand knows in a condensed package.

At its most basic, this is a line-level analogue integrated amplifier, but add the optional digital module for an extra £5600 ($5000, AU$8995) and you get a good range of digital inputs alongside network streaming capabilities, making it a fully fledged just-add-speakers streaming system. Regardless of whether you’re after a straight high-end integrated or something more fully featured, the Progression Integrated is something that must be heard.

Our time with the D’Agostino had us trawling through our music collection, impatient to hear what all those familiar tracks sound like through it. It’s rare to find such a powerful amplifier sounding so transparent and responsive.

Ultimately, it delivers a superb all-round performance. And its modular nature means it offers far greater flexibility than most rivals, too.

Copland doesn't introduce new products all that regularly, so the CSA 100 is a welcome addition to its line-up and a welcome addition to our list of the best stereo amplifiers you can buy.

The CSA 100 boasts a clutter-free and elegant design, with digital module, headphone output and a phono stage all to be found inside that well-constructed chassis. At its core is a hybrid electronic design that produces a solid 100W per channel (8ohm).

Connectivity includes a phono (moving magnet/moving coil) plus single-ended (three) and balanced XLR (one) line-level inputs. As for digital, there’s the usual trio of USB, coaxial and two optical sockets. The Copland's ESS Sabre ES9018 Reference DAC is compatible with up to 32-bit/384kHz PCM files and DSD128.

Sonically, the amp produces a nicely layered image with instruments sharply focused – its sonic precision and a sense of fluidity are hugely appealing. It’s an impressively detailed performer that allows you to just sit back and enjoy your music collection.

This is another amazing (and multi-Award-winning) stereo amplifier from Rega. 

The Elex-R builds on the strengths of the excellent Brio (see earlier in this article), doubling down in areas such as detail, dynamics and timing. Think of the Brio on steroids, and you're pretty much there.

The build quality is as solid as we would expect from Rega, and while the casework is functional rather than luxurious, it’s finished neatly and everything feels like it will last for years. In fact, our unit has been beavering away in our test room for three years and counting, and we're yet to encounter any issues.

We'd avoid sources and speakers that err too far towards brightness or harshness, but otherwise this amp can't fail to shine. The power output of 72W isn’t enough to make the floor shake in really large rooms, but most set-ups should benefit from this amp's many abilities. A great addition to almost any system.

Reasons to avoid

Not the most muscular sound

If it's smoothness, subtlety and sophistication that you're after in a stereo amp, then the Moon 240i has you covered. It's Moon's entry-level integrated amp, though that certainly doesn't mean it comes cheap – Moon is one of those high-end audio brands whose cheapest products are still out of the reach of many. But it's a credit to itself that it looks and behaves like something pricier still.

The curvy silver edges and two-tone effect give the amp serious presence, while the OLED screen is crisp and clear. It sounds like a serious piece of kit, too. Bass notes have a level of detail often missed even by pricier amps, but the 240i doesn't feel the need to shout about it. It's an understated, yet terrifically talented, amplifier - one that puts subtlety and dynamism to the fore.

The Moon also boasts an asynchronous DAC, which supports hi-res files up to an impressive 32-bit/384kHz as well as DSD256 files.

Best stereo amps: Musical Fidelity M8xi

A monster in every (good) way (Image credit: Musical Fidelity)
A super-sized integrated amplifier that delivers the expected muscularity with a surprising degree of finesse.

Specifications

Power: 550W per channel
Phono stage: No
Digital inputs: Coaxial, optical, USB
Bluetooth: No
Headphone output: No
Dimensions (hwd): 18.4 x 48.3 x 51.0cm

Reasons to buy

+
Entertaining presentation combining muscularity and clarity
+
Huge power output
+
Good onboard DAC

Reasons to avoid

-
Huge and heavy
-
Runs warm
-
No phono stage or headphone output

There’s no two ways about it, Musical Fidelity’s M8xi is something of a monster. The integrated amplifier dwarfs most rivals when it comes to size and weighs in at a vertebrae-crushing 46kg. Perhaps the most impressive number is that it has a huge claimed power output of 550 watts per channel in 8 ohms, which then rises to a dizzying 870 watts as the speaker impedance halves.

The M8xi is a poke in the eye for anyone that considers an integrated amp a compromised alternative to a pre/power combination. Inside the Musical Fidelity’s huge frame – 16 x 44 x 40cm (hwd), in case you were wondering – is very much a modular design with DAC, preamp and two monobloc power amplifiers separated as much as possible with the casework.

The M8xi has power to burn and that shines through in its muscular and authoritative nature. You can throw pretty much anything at this amplifier and it’ll never seem out of its depth, yet beneath all that muscle is a product that has enough emotional stretch to satisfy across a wide range of musical genres. The Musical Fidelity M8xi definitely belongs on the shortlist.

Headphone output could be better

This might be an integrated amplifier, but it really is more like a separate pre- and power amplifier in a single box rather than a compromised electrical design. Build quality is excellent. Thanks to its impressive power amp circuitry, this is an amplifier that will have no trouble driving difficult speakers to high volume levels. In other words, it's right up our alley.

It might take a while to fully appreciate its understated presentation. But give it time, and come to appreciate it you will. This is a neutral, balanced delivery, served up with a stunning sense of purity and transparency. And we’re particularly impressed with the way this amplifier can deliver deep bass with such texture, agility and power. Those difficult speakers we mentioned? They'll shake the room when pushed to high volumes.

If you’re looking for a one-stop amplification solution for a high-end stereo system, this Luxman is an excellent place to start.

Faces tough competition

Mark Levinson is one of the most prestigious brands in the high-end amplification space. The firm helped establish the era of high-end hi-fi in the 1970s, and is still one of its leading proponents.

So the No.5805 has quite some legacy to live up to. It's the company's entry-level model (not that you'd know it, from the price tag), and is pretty well equipped on both the analogue and digital front: you get three analogue line-level inputs, including a balanced XLR, alongside a quartet of physical digital connections. There’s a choice of USB, coax and a pair of opticals and a nod to wireless modernity in the form of aptX HD Bluetooth.

Its sound doesn’t grab the attention as firmly or as quickly as some rivals in this list, but over time you can't help but fall for its many charms. The amp's presentation is refined, insightful and dynamic, while the feature set is admirably broad and useful. If you’re in the market for a premium integrated amplifier then the No.5805 is definitely one to consider.

How we test stereo amplifiers

We have state-of-the-art testing facilities in London, Reading and Bath, where our team of experienced, in-house reviewers test every bit of hi-fi and AV kit that passes through our door.

What Hi-Fi? is all about comparative testing, so we listen to every stereo amplifier we test against the current leader in its class to gauge how it compares to the competition. We keep What Hi-Fi? Award-winning products in our stockrooms so we can always pit new products against ones we know and love. We do our best to review as many new models in as many markets as possible, ensuring our contextual knowledge is the best it can be. And we encounter even more during our What Hi-Fi? Awards judging, where we listen to every amplifier manufacturers submit.

We are always impartial in our testing and ensure we hear every product – including stereo amps – at their optimum. So we'll use different partnering products – those in our high-end reference system as well as more price-comparable ones – as well as try plenty of different types of music. Naturally, we 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.
