Quad 3 review

When Quad unveiled a reimagined version of its 1960s 33/303 pre/power amplifier duo in 2023, it proved so popular that an integrated version was highly requested. And so the Quad 3 stereo amplifier was born two years later.

Unlike the 33/303, the integrated Quad 3 isn’t a revived version of an original classic. It’s a completely new and thoroughly modern amplifier designed for today’s demanding customers and their varied listening habits, albeit with a charmingly retro-inspired look.

Build & design

There’s no getting past the eye-catching facade of the amp, so we’ll start there.

The Quad 3’s design takes inspiration from the modernised 33 preamp – the compact size, the controls, the orange-backlit LCD display – while the curved contours are derived from the older, 1950s-era Quad 22 preamp/control unit.

The matte silver fascia is minimally designed and is punctuated with that bright, punchy orange display strip, while the rest of the body sports a dark grey finish.

It’s a nicely made unit and we particularly like that compact size. It sits in between the full-size, bulky Arcam A15+ and the even more compact and tidy Rotel DX-5, and we can see the Quad’s dimensions fitting into many spaces that larger hi-fi wouldn’t.

The front panel of the Quad 3 is adorned with rotary controls mounted flush to the unit, and a larger volume control dial with orange LEDs surrounding it to denote the volume level. The volume dial is nice to use, and we like the way LEDs of varying brightness appear for each volume step.

In fact, it reminds us of a similar design we encountered on the five-star Mission 778X amp. Considering Quad and Mission are owned by the same company, it’s not a huge surprise to see shared designs, and it’s one we’re happy to see repeated on the Quad 3.

The smaller rotary dials are for selecting source, adjusting the balance and bass (up to +3/-3db) and, most notably, the tilt control. This tilt control can trace its origin back to the Quad 34 preamp from 1982, and we find it a subtler way to adjust tone. Instead of separately adjusting treble or bass (as you’ll find on many conventional amps), tilt control allows you to adjust both ends of the frequency range together, pivoting at around the 700Hz mark.

So for a ‘cooler’ sound, you can lift the treble which automatically reduces the same amount of bass (again, in +1/-1db increments), while those wanting a ‘warmer’ tone can go the opposite way, like a see-saw. We think it’s worth playing around with to suit the rest of your system.

Once we get past the rather lovely looks and start using the unit, we start to encounter a few niggles and issues. Firstly – and most egregiously – we wish the text on the display was stronger and had better contrast, as the thin font can be hard to read up close, let alone from afar or at an angle.

The control dials can be a little fiddly to navigate, too. Some on the team preferred using the entire surface of the dial to move it, while others felt it was more natural to adjust it via the bottom lip of the dial that overhangs the display. A little indentation or mark on the dials would perhaps help guide us to the zero point.

The amp comes with a button-laden remote that is useful and responsive, but it feels a little cheap compared with the amplifier itself and with the more svelte, slimline remotes supplied with the Rotel and Arcam rivals.

We wish the button layout was just a little more intuitive, too, especially for changing volume, and that there were dedicated buttons for each input. The source up/down button to change the inputs from afar is pointless when you can’t read the input chosen on the display – and that’s at full brightness/contrast levels.

We find using the source dial on the unit easier to use when switching inputs, but that requires having the amp positioned close to your listening position and within reach.

Features & connectivity

Whereas the modernised 33 preamp is all-analogue, the Quad 3 integrated is a fully 21st-century hi-fi product with multiple digital inputs available. You get optical, coaxial and USB type-B inputs, and even an HDMI ARC input for using the Quad 3 with your TV system. It also has Bluetooth with aptX HD codec for easy streaming from your mobile devices.

On the analogue side, you get two pairs of RCA line level inputs, and moving magnet phono input for connecting a turntable directly. And finally, it has a dedicated headphone amplifier circuit with a 6.3mm headphone jack, just under the front panel.

In short, you can connect just about any source to the amp, and we’re impressed by just how much Quad has managed to fit into this compact amp.

Under the hood, the Quad 3 features Class A/B amplification with a beefy 235VA ultra-low-noise toroidal transformer. The amp has a claimed 65 watts of power into 8 ohms, which rises to 100 watts into 4 ohms – which is perfectly fine for this kind of amp and should be able to drive most price-compatible speakers. We found it had no trouble driving our reference ATC SCM50 speakers during testing.

On the digital side, the Quad 3 makes use of the ESS Sabre ES9038Q2M DAC chip, with special care taken over the clocking circuit to minimise jitter and the power supply circuit to further enhance the DAC performance.

File compatibility is extensive: you get hi-res audio support up to 32-bit/768kHz PCM and full MQA decoding, while DSD512 files can be played natively via the USB input.

There are five filters available to you when using the digital inputs. The default mode is ‘linear slow’ and is the one we settle on as it sounds most natural out of the five options – to our ears, it offers greater subtlety, more dynamism and a better sense of space than the others.

You can access those filters through the menu – here’s where the remote comes in handy – and you’ll also find options to change the brightness of the display (you can turn it off if the orange backlight is too piercing), adjust the text contrast (we recommend leaving it at maximum), choose gain settings, set auto standby and more.

During our testing, we used a variety of sources, including the Naim Uniti Atom Headphone Edition music streamer, the Cyrus CDi CD player, the Rega Planar 3 RS Edition turntable, and an iPhone 16 for Bluetooth. We used price-compatible speakers in the form of the Epos ES-7N standmounts and the PMC Prodigy 5 floorstanders, and we also plugged the Quad into our trusty ATC SCM50s to see how it would fare with more demanding speakers.

Sound

We kick off our listening with a mix of Kendrick Lamar, Alt-J and Waxahatchee, and are met with an immediately likeable presentation that sounds clear and detailed, with a lively sense of energy.

Songs flow in a smooth, fluid manner, while basslines are fairly zippy and nimble – before long, we find ourselves tapping along to songs as we run through our library of tracks. There’s enough punch and verve at hand, too, making it appealing to listen to.

While the scale of sound isn’t as large as more powerful rivals, the Quad 3 is a dab hand with the undulating dynamics of a track. Instruments are layered in a breathable soundstage that has decent depth, with enough in the way of detail that the varying tones and textures of each instrument are clearly conveyed.

Play Eminem’s The Way I Am and the Quad 3 proves it’s no shrinking wallflower; there’s plenty of snap and attack to his singing, with lyrics coming through with ample bite and attitude. The more we listen, we realise the 3’s midrange is the star – from Alicia Keys’ stunningly raw vocals on Fallin’ to Waxahatchee’s crystal-clear, melodious singing, voices are laid bare with a great deal of nuance and expression.

Voices are projected clearly and upfront through the amplifier, and, regardless of the input or source, the Quad 3 does a lovely job in communicating the emotional core of a song. At this level, the stop and start of notes could be more precise and another helping of subtlety and insight would flesh out those instruments and natural tones even further, but the Quad 3 combines the essentials together in a way that sounds cohesive and flows well.

We find the Quad is transparent enough to convey the different recording qualities, too, with the difference in recording eras easy to discern whether we’re playing Nina Simone’s Sinnerman or Dead Prez’s Hip-Hop.

Compared with its price rivals, the Quad 3 isn’t quite the last word in scale, detail and precision. When the sax takes centre stage in Dave Brubeck’s Take Five, for instance, the piano section gets subsumed into the rest of the instrumentation, and isn’t as well-projected as through its rivals.

The pricier and less powerful Rotel DX-5 (£1399 / $1699 / AU$2199) is clearer, crisper, and has tauter bass overall; while the less costly but more powerful Arcam A15+ (£1199 / $1099 / AU$2295) conveys the sweeping, orchestral might of the Jurassic Park Theme with greater muscle, authority, scale and detail.

None of that takes away from the Quad’s full-bodied tone and smoothed-edged presentation, which is a big part of what makes its sound so likeable and enjoyable to listen to in the first place.

That sonic character is consistent through the digital and analogue inputs, which is commendable. The phono stage is of good quality, exhibiting that same midrange fidelity when we play Olivia Rodrigo’s GUTS record on the Rega turntable, although more dynamic prowess wouldn’t go amiss.

The headphone amplifier is also of fine quality, with a great amount of clarity and detail making for an involving and intimate listen. Pair with a solid pair of wired headphones – we used Grado’s SR325x and Beyerdynamic T1 Gen 3 – and it’s a terrific way to enjoy the Quad 3.

The only downside is Bluetooth, which has a noticeable drop in resolution and squashed dynamics, resulting in a very diminished, lifeless performance. While convenient to have, we’d avoid using Bluetooth – it’s not up to the standard of the rest of the Quad 3’s inputs.

Verdict

Quad’s meld of modern and retro has resulted in a characterful, enjoyable amp that, while not troubling the class-leaders at this premium level, has plenty of visual appeal and stands out from the crowd.

The generous spread of connections is impressive for such a compact design, and despite some usability quirks, the Quad 3’s fluid, punchy presentation with its particular talent for voices is worth an audition.
