I cant share a great deal of experience here , but I can say this I own a saffire pro 40 and used the behringer ada 8000 for the adat expansion . I recently bought a second pro 40 because heck , I love the pres on that thing , and I can use both together to get my 16 channels . I can even use the adat on both expand that further . If you like your 18 i 20 , what ' s stopping you from getting a second one for expansion ? <| sep |> Glad you like being a prick ! <| sep |> Yeah I was going to point that out but I just figured he misspoke . Either way though , it ' s generally a lot easier to persuade people when you actually know what you ' re talking about , and it seems like Colin struggles in that regard . <| sep |> the b side probably is , that ' s too good of an idea to pass up
