  Given a quiver, a fixed dimension vector, and a positive integer n, we
construct a functor from the category of D-modules on the space of
representations of the quiver to the category of modules over a corresponding
Gan-Ginzburg algebra of rank n. When the quiver is affine Dynkin we obtain an
explicit construction of representations of the corresponding wreath-product
symplectic reflection algebra of rank n. When the quiver is star-shaped, but
not finite Dynkin, we use this functor to obtain a Lie theoretic construction
of representations of a "spherical" subalgebra of the Gan-Ginzburg algebra
isomorphic to a rational generalized double affine Hecke algebra of rank n. Our
functors are a generalization of the type A and type BC functors from
arXiv:math/0702670 and arXiv:0801.1530 respectively.
