Use Interfaces and Small Classes - Seemann

Lots of small classes sounds just fine :)

Particularly if you let each class implement an interface and have the different collaborators communicate through those interfaces instead of directly with each other, you should be able to achieve a so-called Supple Design (a term from Domain-Driven Design) with lots of loose coupling.
