I have the N804's and they are very good speakers with classical, they are outstanding speakers with jazz and pop, and they are good (not great) with rock. I push my speakers with Levinson and I feel that Krell would be as good. It all depends on your taste. All in all you will not go wrong with the combo you've asked about. Peace and Good Listening,Pat. A Proud Vet!!!!!!!! God Bless America!
