Couldn't quickly find the RM5SE manual online, but if it has the same RCA output configuration as the 5.1, you can use any good quality RCA interconnect. You don't have to have an integrated ground lead in the IC as any insulated conductor will do (e.g. doorbell wire). I like my Cardas Golden Reference phono IC, but that is a specific configuration, custom length DN to RCA cable required for my installation. Set me back about $475 if I recall correctly.
