Behringer
Personally, I think if you have the money to buy the original name high end products, you are going to do that if nothing else to impress your potential clients by using the names in your studio equipment list.
If Behringer are making the same product for a fraction of the cost, then it is for the people who have home studio's that can't afford the big name gear.
I don't think that API, NEVE, Nuemann, Avalon etc . and all the big name guys have lost any business because of the Chinese companies that rip them off and sell for a fraction of the price, (although I don't know this for a fact).
The budget studio owner doesn't have the money to buy a bunch of big name gear to start with, so they will buy cheap gear, and as I said before, if you have a huge account, you're going to buy Neumann, API etc. anyway.
I think Behringer are a good product at a cheap price.
If you have a good pair of ears, you can get cheap gear to sound every bit as good as high end gear, and if you don't have the ears, you can have an SSL in your basement, Urei pre's 480 XL etc. and turn out a bad product.
