So far 5 stars...

I have only had this guy for a few weeks, but so far it is sweet! I haven't had any time to really record stuff with it yet, but I have done a few soundchecks... It sounds totally crisp and clean! I will continue this review after I have used it a bit more!

effective and versitile

had a slight issue with the power input socket when I first got it but the guys at focusrite set me straight and treated me well. I use this thing every day in conjunction with 18i20 with ease and the mixing allows for excellent submixes and headphone mixes for small recording situations

Versatile interface with impressive preamps and headphone mixes

I was in search of an interface that provided separate headphone mixes, and more than one. I also heard countless time about how solid Focusrite's pres are. They don't disappoint! This is the soul of my studio.
