Universal Audio is one of the most respected names in audio. They got into the home studio interface game a few years ago with the ever-popular Apollo series. 

The Twin X DUO’s performance is comparable to UA’s rackmount Apollo X audio interfaces but does away with extraneous features like 5.1 surround monitoring and +24dBu operation.

As a result, you get a streamlined desktop design that’s tailor-made for project studios. You can also track and mix with spot-on emulations of tried-and-true studio classics, thanks to UA’s powerful DUO Core processor. The Apollo Twin X is our most versatile choice. 


  • 10-in/6-out Thunderbolt 3 audio interface with onboard UAD-2 DUO Core processing
  • World-class AD/DA conversion for ultra-pristine signal path with 127 dB dynamic range
  • 2 Unison preamps to track through models of the industry’s most legendary hardware

This fantastic interface also comes with UA’s LUNA software, for a tightly integrated recording, editing, and mixing environment, with full software-based control over your interface’s parameters.

(Check out our full review of LUNA here!)

As far as the preamps, Apogee’s Advanced Stepped Gain Architecture ensures clean, low-distortion results, with up to 75 dB of gain.

On top of that, the Alloy Mic Preamp emulations employ both analog circuitry and digital processing to create some of the most authentic modeling available, including a Solid State Class A sound inspired by the legendary British console and a gently overcooked American tube sound.

If you’re a Logic X user, you’re going to love this interface as it allows you to take full command from directly within Apple’s software. This is thanks to Apogee’s DualPath Link.

DualPath allows you to dial in your sound l, without printing the effect. You can also save your plug-in settings, so you have the option of adjusting the effect parameters later during the mixing phase.

Using the Symphony Desktop and Logic Pro X together allows you to work with just a single window in the DAW.

Additionally, the Symphony Desktop comes with the Bob Clearmountain-tweaked ECS Channel Strip plug-in. In short, it is hard to beat the sheer quality and functionality of the Symphony Desktop.

The Scarlett 2i2 also features innovative halo indicators that ensure you’re getting a proper signal level for recording.

This is especially useful if you’re starting out with recording. If the halo is red, your signal is clipping, and you should back down your gain. The halo will momentarily turn amber as the level returns to a happy level.

If portability is a must, we’ve got good news: the 3rd Gen Scarlett interfaces can now be used by iPad Pros with USB-C ports. Simply plug in, open your music-making app of choice, and record to your heart’s content just like you would at home. It’s as effective and simple as it gets.
