I have owned a 4BST for about two years and heard it in a few applications, but not the B&Ws. However, it is extremely smooth for a solid state amp and offers tremendous bottom end control and pitch. If you are considering affordable solid state, it is hard to beat. I am presently using the amp to drive 18 inch sub-woofers and it is just shy of some other amps I have on hand which cost considerably more. I am considering selling mine, but haven't been sure enough to advertise it yet. It is the only reasonably priced piece in my system and holds its own quite well. I'm not sure what else you could find for the money which would be a better overall amp. Best of luck and let me know if you are interested.
