Mani 2's with the right amp, and in the right room is a better speaker.
The same can be said about the M-1. My first real a-ha moment in audio was at a dealer that had M-1 Si vertically biamped with a pair of Krell KSA-250s in a large room. I have heard a number of 2 way monitors, and none are capable of doing what those speakers did in that room with those amps. I don't know that he has the right amp for either speaker as both are power hungry. The Mani is probably the better fit for that room. The Mirages need a big room with the ability to get them well out from the front wall.
