Coincidentally I auditioned the Alexia 2s and the new PMC Fenestria back to back yesterday and today. Alexia 2s at a dealer, driven by Naim Statement monos, and Fenestria at the Festival of Sound show in London, driven by AVM 1.2KW monos. There was absolutely no comparison, the Fenestria blew the Alexia 2s, and everything else at the show out of the water. It could be the room or setup, but the Alexia was in a somewhat treated dedicated listening room, while the PMCs were in an untreated hotel conference room.
Alexias sounded like really nice hi-fi speakers, sounded great on certain instruments and voice. I do think the setup wasn't done 100% properly. The Fenestria, they were simply stunning, my jaw was open for the first 3 songs. It's just a whole wall of music with precise image that wasn't picky about sweet spot, uniform and yet layered presentation, incredibly detailed and balanced with refined yet impactful bass.
If you are looking to spend Wilson Alexia money, please do yourself a favor and audition the Fenestrias.
