Focusrite Clarett 4 Pre
Pros +High quality preamps +Added ‘air’ feature for versatility +More connectivity options |
Cons –Pricier than the Scarlett series –No Splice subscription included |

The Focusrite Clarett 4 Pre is almost identical to the Scarlett 18i8; the big brother of the Scarlett 2i2 that you read about earlier. Both have 4 mic/instrument inputs, 2 headphone outputs, 4 line inputs, 4 line outputs, MIDI, optical, and SPDIF I/O. The Clarett also comes with exactly the same large range of plug-ins, emulations, instruments, and DAWs to keep you busy in the studio. Both also feature the added ‘air’ mode, giving you the diversity of two preamp sonics in one audio interface.
So, what’s the difference? Well, it’s all in the components and preamps. The Clarett has superior ones which bring out more high-end detail and colour with minimal distortion. You also get increased headroom, better noise handling, and superior latency management. So, if you’re recording a lot of instruments at once, you’re less likely to experience any time issues.
So, is it really worth the extra money? If you really want better quality audio, then yes. That’s not to say the Scarlett sounds bad in any way, shape or form; but with the Clarett you just get that little bit extra. You get a richer, detailed sound, with more colour and character. If you can push your budget that bit further, it’s definitely worth investing in an interface from the Clarett series, over the Scarlett series.

Universal Audio are a very reputable, established company with a solid line of audio recording products. Their Audio Apollo is a very user friendly and time saving interface, as it has a number of touch controls, giving it the feel of an analogue device. The buttons have a variety of functions and shortcuts, for quicker workflow in your studio, and the convenient large knob in the middle controls monitor and preamp levels.
The Apollo Twin features standard ins/outs, plus an optical in, allowing you to expand your recording ability to 64 channels, by connecting to other audio interfaces. Perfect if you want to develop your studio later on. The colourful and vibrant LEDs are used for monitoring gain levels and volume, making it convenient for you to visually see what you’re hearing.
Another justification for the higher price, is the supreme audio quality. The Unison preamps deliver excellent dynamic range with minimum distortion. The preamps also can be used in conjunction with the enormous range of award-winning UAD plug-ins that are included with the interface. The library has a selection of vintage EQs, compressors, amps, reverbs and tape machines, from massive companies such as Neve, Studer, Manley, API, Ampex, Lexicon, Fender and more.
The combo of these preamps, and the vintage UAD plug-ins, allow you to bring your music forward into a rich, sonically complex analogue sound. Yes, it’s a little more expensive, but if you’re looking for a lush sound, sleek style with expansion possibilities, then this is the perfect interface for you. UA also offers the Apollo Solo with less inputs for a lower price tag if you’re on a budget.

If you’re a Mac user and want something sleek, programable, with a touch-based interface, look no further than the Apogee Quartet. This elegant, aluminium audio interface is incredibly stylish and works effortlessly with Mac devices, including iPads and iPhones.Windows users, don’t stress though, the Apogee One, Duet, & Quartet are now compatible with Windows 10.
The Apogee Quartet features attractive OLED screens that display levels, meters and pertinent information, speeding up your workflow. The touch buttons give you an audio interface that you can interact with, allowing for quick hands control for functions such as select, dim, gain, volume, or you create custom shortcuts with the ABC buttons.
Ok, so it looks fancy and has some nice features, but why else the high price tag? Well, underneath the elegant aluminium are some killer preamps and components. Offering flawless audio quality, that is clean, crisp, detailed and warm. You won’t find that kind of audio quality on cheaper devices.
If you don’t need as many inputs as 4, but still want this highly functional and stylish interface, Apogee offer two smaller models. Apogee One features 1 mic and 1 instrument input, and Apogee Duet features 2 mic and 2 instrument inputs. They are all expensive interfaces, but well worth it if you’re looking for something unique and sophisticated that speeds up your workflow.
Apogee Ensemble
Pros +Attractive design +Lots of I/O options +Plenty of buttons & knobs |
Cons –Expensive –No cable supplied –Less line inputs –No DAW(s) or software included |

Unlike the Apogee One, Duet, & Quartet, the Apogee Ensemble is unfortunately not currently compatible with Windows. Sadly, Windows users will have to give this one a miss. This doesn’t stop this interface from being an absolute beast though! For Mac users this is the ultimate choice but only if you can afford it, because it certainly isn’t cheap.
So, what does the Apogee Ensemble bring to the table, that makes it so expensive? 6 line inputs, 8 mic inputs, 2 dedicated guitar inputs/outputs, 2 headphone outputs, monitor outputs, analog sends/returns, 2 optical inputs/outputs, an SPDIF and world clock I/O configuration. They have also included a built-in talkback mic, input/assignable buttons, and controller knobs for volume.
Phew… that was a lot to write. Needless to say, you have an enormous amount of options and flexibility with this interface. You have two thunderbolt connections, one to connect to your computer, and the other can be connected to another Apollo Ensemble, or Element device. The thunderbolt connectivity gives you the lowest latency of any audio device, according to their website.
At this price the sound quality is flawless. The preamps feature Apogee’s Advance Stepped Gain Architecture, which optimise superior bandwidth, ultra-low noise, and non-existent distortion. You also get Apogee FX Rack plug-ins featuring EQs, compressors, limiters, effects and more.
This is THE interface for pros working with Mac devices. Once you’ve bought this interface, you won’t need another one unless you want to expand your I/O capabilities massively. It’s pricey, but your studio will thank you for the long-term investment. It does however lose some points as no DAW(s) or software is included. It would also be nice if Apogee made it compatible for Windows.

The Universal Audio Apollo 8 is certainly not cheap, but if you have the budget, and really want to have one of the best quality audio interfaces, this may be the one for you. The Unison preamps give this digital audio interface a classic analog sound, by emulating sought-after tube and solid-state preamps, true to the sonic characteristic of the original hardware.
This is achieved by using Apollo’s Console software, simply add a plug-in on your input channel, and you have instant access to the world’s most recorded preamps from Neve, SSl, Manley and more. You also get access to a lot of EQ units, compressors, vintage amps, reverbs and tape machines.
The Apollo 8 really looks the part, with its sleek, stylish appearance, and robust build quality. In fact, you may even get distracted by admiring it in your studio, as it catches your glance. The bright LEDs on the front of the interface also make for effortless monitoring, that is pleasing to the eye.
All of the Apollo devices can be synced together, so if you already own an Apollo Twin, 8, 8p, or 16, you can combine them adding more I/O options. This a highly professional level audio interface for those with a bigger budget, and if you want access to a sublime collection of classic analog hardware, emulated by the UAD plug-ins.
Don’t Overthink it!
Choosing an audio interface is not easy, but I hope that this guide on the best audio interfaces has given you a clear idea. Ultimately, one of the most important factors for you is likely to be price.
Studio gear can eat into your budget pretty quickly, but it is easier and cheaper than ever before to build your own studio without breaking the bank. As most of the audio interfaces listed above come with bundle packs, you will be in a great position from the get-go to record and mix your music on a pro level.
Don’t overthink too much which one to purchase. They all serve the same basic function of getting audio in your computer. All of the products in this list have a renowned reputation for longevity, reliability, and quality. So, whichever you choose will serve you well.
