I was comparing the pre's to the pre's I'd previously used in my schools Soundcraft mixer, the Mackie mixer and the Phonic.
That Phonic......... worse than the Behringer.
I thought the Mackie was the best of them all, but in terms of cost to quality it was way too expensive, in Britain at least.
The Soundcraft was good and probably what I'd upgrade to next.
Don't take my opinion as amazing though - I'm just a physics student with a strong interest in music and recording.
