Hi Smjason. I used to own Simaudio Moon I-5 and ran it with an NHT SW3P subwoofer. The NHT has only line level inputs, so I used the pre-outs on the back of the I-5 to feed the subwoofer amp. I had no impedance matching or gain problems at all between these two components.
I don't know what kind of output options the Velodyne has, but if you do decide to go with a REL I would follow the advice of the previous posters and connect the I-5 via the amp/speaker binding posts instead of the pre-outs. I think REL recommends this method over line level.
Good luck.
