Magico A3 vs. Wilson SabrinaX

When I demoed the Magico A3s, for a long period in a good room with good amplification, one of the main off-putting aspects to me was a lack of dynamic life.  They were the epitome of the audiophile speaker that disappears, has excellent tone and detail, but just did that sort of leaving the musicians "sitting there" behind the speakers in a 3D way but without the sense of dynamic excitement.


I came home and played the same tracks on my Thiel 2.7s, which are lower sensitivity and hooked up to lower powered amps than the Magico were, and the sound that was flat on the Magicos leapt to dynamic life on the Thiels.   



FWIW...which isn't too much as it's only one guy's experience. 

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.

What's sad is that no one got my ebm tribute............
