RE: Kinergetics KBA-75

I am hoping someone can tell me what the two sets of RCA jacks on this amplifier are for. There are two RCA's on each side labeled input...are they both the same?
I'm pretty sure they are to run balanced interconnects without having to use the XLR connector. Simaudio uses the same setup on the W5.
Do you stil have this amp? What do you think of it? What have you compared it to?
