Great news! Happy to help! 

And good to have further evidence of the Proprius's compatibility with REL's 3-wire connection, despite REL's general concerns with monoblock amplifiers.

My current amps are dual stereos bridged to mono - one of the cases that REL's advice is most concerned with, because of the way the bridging is implemented. In this mode you connect speaker +ve to right amp +ve and speaker -ve to left amp +ve (!), and the left channel plays the inverse of the right. There is no speaker connection to the amp -ve terminals, which stay at 0v.

This also works absolutely fine with the 3-wire connection for a single REL, provided that the black wire goes to 0v (either left or right amp -ve of either amp, so basically any black-coloured speaker terminal). Connecting it to the same -ve that the speakers see would be a potentially damaging error, because it isn't 0v in this configuration.
