A bit late here, but...
I’m running Wilson Sophia 3s with the Pass XA25. The Sophia’s are ~87db/1W efficiency. They are made easy to drive (nominal 4Ohm impedance), but not all that efficient. I’ve had the XA25 since last Summer.
90 - 100 db is about the loudest I’d listen to, so the Pass is barely loafing most of the time at 1 - 3 watts or so. (I thought I needed high-power too until I actually tried the XA25, thanks to Reno Hi-Fi’s trial period.)
I can turn it up louder than I want to listen to it without any noticeable compression, soundstage collapse, or clipped transients or dynamic swings.
I posted some comments on my experience with the XA25 on other threads (you can search my threads or for XA25). It’s keeper for me.
