You can consider the Clarett 8pre as a "premium" version of the Scarlett series.

The Clarett range features upgraded preamps with a different sonic quality, additional headroom, a more sophisticated implementation of the ISA "Air" mode, and reduced latency with newer technologies making their appearance.

The primary reason users love the Clarett series is the upgraded preamps carried over from Focusrite's iconic ISA series. Many users note that the preamps alone are worth the cost of the entire unit and that the functionality as an audio interface is only a bonus.


Was expensive for some users and some feel like it's a matter of diminishing returns as only the keenest ears can notice the difference between the 8Pre and Focusrite's Scarlett 18i20.


The Clarett series is the Scarlett series taken to the next level by integrating Focusrite's top tier ISA series preamps into an audio interface. Get it if you're a fan of getting great sound straight from the input.
