Magico A3 vs. Wilson SabrinaX

I listened today to the Totem Metal 2 - very nice speaker. Also to the Sonus Faber NOva V: Impressive, but most likely need to be well out of back wall.
I would think that the Totem Metal V2 are comparable to the SabrinaX to a degree - Anyone with a similar experience for these 2 speakers?

The notion of impedance is something I have a hard time to understand. In my mind, a lower impedance means a higher output (more dynamics): Am I getting that completely wrong?In other words, If I have a 6 ohm speaker, sensitivity at 91db, then I assume that a 4 ohm with a sensitivity of 88db should be fine to run with the same amp (here a XA25 that you all know). I’m not a sound engineer for sure!!
As a result, I believe that I could run the Wilsons SabrinaX without too much trouble, for instance. Thoughts, guidance?

The Wilsons don’t hold a candle to the Magicos, but you need a trained ear to get it. They will not jump on you like some other speakers, but they will be a much better companion for the long run.
