I've heard the Sabrina X as well as the Sasha's. Have not heard the PS Audio or the Rockports.
Bought and installed the A5's about a month ago. So far, they sound amazing! For those that have not heard this Magico, it is not the least thin sounding or bright, like previous models from this manufacturer. If anything, it is a bottom up speaker with a slightly warm tonality. Except it has incredible detail and disappears in the room,
I like it better than the Sasha's, never mind the Sabrina X.
A little back round: I've owned various Wilson's near 30 years, so I am a Wilson fan.
Currently also have a Joseph Audio Pulsar 2 Graphene in a second system, also a great speaker and better IMO than the Wilson's.
