Well I also have Monarchy SM70 Pro's and I agree with all that the posters above say, except the non-recommendation for running them single ended. I wouldn't know about balanced operation, but they are just wonderful running single ended in my system.
I have to say I didn't like the result running the amps as bridged monoblocks, though I really wanted to. Hard to explain, but they sounded rather 2 dimensional and midrangy each time I pushed the volume as monoblocks.
Vertically bi-amped though is a completely separate animal (running both amps in stereo mode) and they sound very good, and even quite transparent partnered with my tube preamp.
Highly recommended!
