I like Revel, but the Salon2 isn't a very kind speaker for some amplifiers. Soundstage is exceedingly wide and deep, but just shy of being as finely drawn out on the stage. It has stood up amazingly well over the test of time, but well set up you would likely enjoy the sound.
Very little is known about the Magico A3, but from what has been said thus far, it seems that certain updates might make it a bit more forgiving over previous Magico designs. It also has a fairly small footprint and is a sealed design that seems to be able to reach fairly low in bass response. I'm sure some concessions will surface, but no one truly knows for now. One thing for sure, it won't win any beauty contests.
