Go with the Pass amps for sure. I have owned the Monarchy SM 70 Pros, and while they are good amps, they are not in the same league and have some issues. They each require an aftermarket power cord to sound their best and they have too much gain for the voltage input ( especially in balanced operation). I was using the Aleph P preamp with the monos and there was not enough low volume control. In other words the volume was too high even at one click up! I am now using a Pass Aleph P into a Aleph 3 into a pair of Sonatinas (Avalon style, 93db @ 8 ohms) and have plenty of gain and control. The Monarchy amps would be better with less efficient speakers or a lower gain preamp.
