It depends. For most cases I personally prefer 1) where the factory is 
only a real factory for creating components and therefore passes everything
on to the Source object.

Solution 2) can be/is used where it is possible to reuse concrete Source
implementations. This means for example two different factories use the
same Source implementations and therefore create the necessary parameters
and pass them on.
