I have a Harmon Kardon HK3480 driving a pair of polk audio rti8's. IF I were to get a Rotel RB 1070 amp...will I be getting any significant change in sound? Reason I am asking is because I know both units are respectivly known for their specs and quality of parts. And these two models have roughly the same wattage outputs.
