Best stereo amplifiers 2021
Stereo 5w audio amplifier board 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, is now no longer the norm.
With laptops, smartphones and streaming services becoming ever-more popular music sources, the integrated amplifier has moved with the times. Many now contain built-in digital-to-analogue converters (DACs), phono stages for turntables, USB connections and Bluetooth streaming functionality. Some even have network streaming integrated.
We’ve rounded up a wide selection of the best integrated amps on the market, offering a vast selection of features across a range of prices. We’re confident there should be something to suit all budgets and requirements, and get your music system singing.
The new 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.
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 apart from this, 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, 5w audio amplifier board full-bodied and balanced, with a pleasing spaciousness. Another quality hi-fi amplifier from Marantz.
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 2019 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.
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. It’s a whole lot of fun to listen to. In terms of stereo speakers, we’d look to partner the Rega with something like the Elac Debut 2.0 B6.2 or Bowers & Wilkins 606.
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 in 2020.
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, earning a well-deserved five stars, and picking up a 2019 What Hi-Fi? Award 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.
